Choosing a truck mounted crane is rarely as simple as deciding how many tons you need.
Two cranes with a similar rated lifting capacity can perform very differently once boom length, working radius, chassis configuration, outrigger design, hydraulic system, jobsite access, and daily transport requirements are taken into account.
That is why understanding the different truck mounted crane types is an important first step for contractors, equipment distributors, construction companies, utility operators, logistics companies, and industrial buyers.
A truck mounted crane combines lifting equipment with a road-going vehicle, allowing one machine to travel between jobsites and perform lifting work without relying on a separate crane carrier. Depending on its configuration, it may be used for construction materials, machinery installation, utility maintenance, logistics handling, municipal projects, power infrastructure, and many other applications.
This guide explains the main types of truck mounted cranes, how they differ, where each configuration fits best, and what buyers should compare before requesting a quotation.

What Is a Truck Mounted Crane?
A truck mounted crane is a lifting system installed on a truck chassis or purpose-built vehicle platform.
The truck provides mobility, while the crane provides the lifting function. Depending on the machine design, the crane may be installed behind the cab, toward the rear of the chassis, or integrated into a specialized crane vehicle.
Most modern truck mounted cranes use hydraulic systems to control boom lifting, extension, rotation, outriggers, and other movements.
For buyers, the biggest practical advantage is mobility. Instead of transporting a conventional crane separately, a truck mounted crane can move between worksites under its own power, set up its stabilizers, complete the lift, and then travel to another location.
This makes the equipment particularly useful when lifting tasks are spread across multiple locations.
Typical applications include:
- Construction material handling
- Equipment installation
- Utility and power projects
- Road and municipal maintenance
- Machinery relocation
- Logistics and warehouse operations
- Steel structure installation
- Pipeline projects
- Water conservancy construction
- Emergency and maintenance work
However, not every truck mounted crane is designed for the same job. Understanding the different configurations is therefore more useful than comparing only maximum tonnage.
What Are the Main Truck Mounted Crane Types?
There is no single universal way to classify every truck mounted crane. Buyers normally compare them according to boom structure, lifting capacity, chassis design, installation position, and intended application.
For practical procurement purposes, the most useful classifications include:
| Truck Mounted Crane Type | Main Feature | Typical Use |
|---|---|---|
| Telescopic Boom Truck Mounted Crane | Straight hydraulic boom with extendable sections | Construction, utilities, equipment placement |
| Knuckle Boom Crane | Articulated folding boom | Loading, logistics, compact-site work |
| Light-Duty Truck Mounted Crane | Lower lifting capacity and compact vehicle | Municipal work, maintenance, light materials |
| Medium-Duty Truck Mounted Crane | Balance of capacity, reach, and road mobility | General construction and industrial work |
| Heavy-Duty Truck Mounted Crane | Higher lifting capacity and larger support structure | Infrastructure and heavy equipment |
| Cargo Truck with Crane | Crane combined with a cargo deck | Self-loading and material transport |
| Specialized Truck Crane | Vehicle designed mainly around lifting performance | Higher-duty lifting projects |
The right choice depends on what the crane needs to lift, how far the load must travel horizontally, how high it must be placed, and how frequently the vehicle needs to move between worksites.
Telescopic Boom Truck Mounted Cranes
The telescopic truck mounted crane is one of the most common configurations used in construction and industrial lifting.
Instead of folding through articulated joints, the boom consists of several sections that extend outward from one another. Hydraulic cylinders and extension mechanisms allow the operator to increase the boom length when additional reach is required.
This configuration provides a relatively straightforward lifting path and can offer considerable vertical reach.
Telescopic cranes are commonly used for:
- Construction materials
- Steel structures
- Equipment installation
- Utility poles
- Electrical equipment
- Municipal projects
- Machinery handling
- Infrastructure construction
Boom section count is an important consideration.
A crane with more telescopic sections can potentially provide greater reach while keeping the retracted boom relatively compact. However, the buyer should never compare boom length alone.
The more important question is:
How much capacity remains at the working radius you actually need?
For example, Sitong’s 8 Ton Dongfeng Truck Mounted Crane provides one reference point for buyers evaluating mid-capacity telescopic configurations.
For projects requiring significantly more capacity, Sitong also offers a 20 Ton Truck-Mounted Crane with an eight-section telescopic boom.
The correct configuration depends on the lifting task rather than the longest available boom.
Knuckle Boom or Articulating Truck Mounted Cranes
A knuckle boom crane uses multiple articulated boom sections connected through hydraulic joints.
Because the boom can fold into a compact position, this design is often associated with cargo handling, loading and unloading, utility work, recycling, forestry, marine operations, and jobs where working space around the truck is limited.
Compared with a straight telescopic boom, an articulating boom can offer useful maneuverability around obstacles.
For example, operators may need to place loads beside a structure, behind an obstruction, or into an area where a straight lifting path is difficult.
Typical advantages can include:
- Compact folded dimensions
- Flexible load positioning
- Good close-range handling
- Efficient loading and unloading
- Useful operation around obstacles
But a knuckle boom is not automatically better than a telescopic boom.
A telescopic crane may be more suitable when the priority is long vertical reach and straightforward boom extension, while an articulating crane may be attractive when compact folding and load positioning are more important.
For safety and technical guidance relating specifically to articulating boom cranes, buyers operating in markets that use North American standards can refer to ASME B30.22.
Light-Duty Truck Mounted Cranes
Light-duty models are generally chosen when extreme lifting capacity is unnecessary and vehicle maneuverability matters more.
These cranes can be useful for companies handling relatively lighter materials while traveling frequently through urban areas, industrial parks, service roads, or smaller construction sites.
Common jobs include:
- Building materials
- Small machinery
- Landscaping equipment
- Municipal maintenance
- Utility components
- Maintenance tools
- Light steelwork
A smaller truck mounted crane can also require less operating space than a larger heavy-duty machine.
However, buyers should resist the temptation to choose the smallest crane that can theoretically lift the load.
If the actual job requires lifting at a longer working radius, the available lifting capacity can be much lower than the maximum capacity stated in the model name.
A 5-ton crane, for example, does not necessarily lift five tons at every boom length and radius.
Maximum rated capacity generally applies only under defined operating conditions.
This is why the crane’s load chart should always be reviewed before purchase.
Medium-Duty Truck Mounted Cranes
For many contractors, medium-capacity equipment provides the most practical balance between lifting capability and transport flexibility.
Configurations around this part of the market are commonly used for construction, utilities, industrial maintenance, machinery installation, infrastructure work, and general material handling.
Sitong’s current truck-mounted crane range includes several configurations in this area, allowing buyers to compare different chassis and crane combinations.
A medium-duty machine may be appropriate when you need:
- More lifting margin than a compact crane
- Useful boom reach
- Road travel between multiple jobsites
- A manageable overall vehicle size
- Versatility across different lifting jobs
For example, an 8-ton configuration may suit a contractor whose daily workload involves building materials and medium machinery, while a 12-ton machine may provide greater capacity and working range for more demanding projects.
The important point is that tonnage alone should not determine the purchase.
The complete operating envelope matters.
Heavy-Duty Truck Mounted Cranes
Heavy-duty truck mounted cranes are designed for larger loads, greater lifting heights, heavier-duty structures, and more demanding working conditions.
These machines may be used in:
- Large construction projects
- Infrastructure installation
- Heavy machinery handling
- Power projects
- Industrial facilities
- Large structural component installation
- Water conservancy projects
As crane capacity increases, supporting systems become increasingly important.
Buyers should pay close attention to:
- Chassis strength
- Axle configuration
- Crane subframe
- Outrigger design
- Hydraulic capacity
- Slewing system
- Boom construction
- Overall vehicle dimensions
- Ground bearing requirements
Sitong’s 20 Ton Truck-Mounted Crane provides an example of a heavier configuration. It uses an eight-section telescopic boom and a larger outrigger system intended to support higher-capacity work.
Moving up to a heavier crane should be based on actual project requirements rather than simply purchasing the largest machine available.
A larger crane also requires more space, stronger ground support, different transport considerations, and potentially higher operating costs.
Cargo Trucks With Mounted Cranes
One of the most useful truck mounted crane types for logistics and material transport combines a hydraulic crane with an open cargo platform.
The vehicle can carry its own materials and use the mounted crane to load or unload them.
This can reduce dependence on separate forklifts, loaders, or lifting equipment at every destination.
A typical work cycle might look like this:
Load → Transport → Arrive → Deploy Outriggers → Lift → Unload → Travel to Next Site
This configuration can be especially useful for:
- Construction material delivery
- Utility equipment transport
- Pipe handling
- Precast components
- Machinery delivery
- Steel structures
- Landscaping materials
- Municipal equipment
For companies that repeatedly deliver heavy materials to sites without permanent lifting equipment, combining transportation and lifting in one vehicle can improve operational flexibility.
However, buyers must consider the interaction between the crane, chassis, and cargo capacity.
Adding a larger crane does not automatically make the vehicle more useful if crane weight reduces the practical payload too much.
The complete truck should therefore be selected as an integrated system.
Truck Mounted Crane vs Truck Crane: Are They the Same?
The terminology can be confusing because names vary between countries, manufacturers, and equipment markets.
“Truck mounted crane,” “crane truck,” “lorry crane,” and “truck crane” are sometimes used interchangeably.
But in purchasing discussions, they can describe somewhat different machine concepts.
A truck mounted crane often refers to a crane installed on a commercial or modified truck chassis. Depending on the configuration, the vehicle may also retain a cargo deck for carrying materials.
A dedicated truck crane, by contrast, may be designed more specifically around lifting work, with less emphasis on carrying cargo.
A simplified comparison looks like this:
| Factor | Truck Mounted Crane | Dedicated Truck Crane |
| Main role | Transport + lifting or mobile lifting | Primarily lifting |
| Cargo capability | Often available | Usually less important |
| Road mobility | High | High |
| Typical jobs | Materials, utilities, logistics, construction | Construction and heavier lifting |
| Vehicle configuration | Commercial or specialized truck chassis | More crane-focused carrier |
| Job flexibility | Very high | High |
Terminology alone should never be used to make a purchasing decision.
Instead, compare actual specifications, load charts, chassis, boom design, and application.
How Lifting Capacity Changes Between Crane Types
Maximum lifting capacity is one of the first figures buyers notice, but it is also one of the easiest specifications to misunderstand.
Suppose a crane is marketed as a 12 ton truck mounted crane.
That does not mean it can lift 12 tons throughout its entire working range.
As the working radius increases, available capacity normally decreases.
Sitong’s 12 Ton Truck-Mounted Crane demonstrates this clearly in its published performance table. Its rated capacity varies substantially depending on boom configuration and working radius.
This relationship is fundamental to crane selection.
Before choosing among different truck mounted crane types, determine:
Load Weight
How heavy is the actual object being lifted?
Include lifting accessories and rigging where required.
Working Radius
How far horizontally will the load be from the crane’s center of rotation?
Required Height
How high must the load be placed?
Boom Configuration
How much boom extension is needed?
Operating Area
Will the lift occur over the side, rear, or another permitted working zone?
Outrigger Configuration
What outrigger position is required by the manufacturer’s load chart?
Official crane regulations also emphasize the importance of manufacturer load charts. OSHA’s requirements for truck cranes, for example, address clearly visible load rating information for operators. Buyers working in the United States can review the relevant OSHA truck crane requirements.
Choosing Truck Mounted Crane Types by Application
A crane that performs well for a logistics company may not be the best choice for a power contractor.
The work should determine the machine.
Construction and Infrastructure
Construction teams often need good vertical reach, useful lifting capacity, frequent repositioning, and the ability to travel between sites.
Telescopic truck mounted cranes are commonly well suited to these requirements.
Sitong provides additional information about lifting equipment used for construction and infrastructure applications.
Power and Utility Projects
Power infrastructure projects may involve:
- Transformers
- Utility poles
- Switchgear
- Cable equipment
- Maintenance components
These applications may require reach as much as raw lifting capacity.
A crane that can safely place equipment at the required radius is more useful than one with a higher headline capacity but insufficient working range.
Logistics and Warehousing
For logistics work, repeated loading and unloading may make a cargo truck with a mounted crane particularly attractive.
Cycle time, control smoothness, cargo deck arrangement, and overall vehicle maneuverability become important selection factors.
Manufacturing and Industrial Facilities
Industrial buyers often need cranes for machinery installation, maintenance shutdowns, equipment movement, and component handling.
Accurate load placement may be more important than maximum speed.
Municipal Projects
Municipal operations may involve road maintenance, drainage equipment, landscaping materials, lighting systems, and public infrastructure.
Compact vehicle size and frequent road travel can be important.
Water Conservancy Projects
Water infrastructure sites may involve uneven access, larger components, and challenging ground conditions.
Buyers should consider vehicle mobility, outrigger support, and jobsite access alongside lifting capacity.
Telescopic Boom Length vs Working Radius
Longer boom reach is attractive on a specification sheet, but boom length should never be evaluated by itself.
The most useful question is not:
“How long is the boom?”
It is:
“What can this crane safely lift at my required radius and height?”
Imagine two machines:
Crane A offers a longer maximum boom.
Crane B has a slightly shorter boom but provides more useful capacity at the radius where your normal lifts occur.
For your actual project, Crane B may be the better machine.
This is why professional crane purchasing should begin with the real lift geometry.
Prepare a simple operating profile showing:
- Typical load
- Maximum load
- Pickup radius
- Placement radius
- Required height
- Ground conditions
- Available setup area
Send this information to the manufacturer when asking for a recommendation.
It allows the supplier to compare the relevant portion of the load chart instead of guessing based on tonnage.
Why Chassis Selection Matters
The truck chassis is not simply a platform underneath the crane.
It affects the entire machine.
Important factors include:
- Gross vehicle weight
- Axle distribution
- Wheelbase
- Turning radius
- Road speed
- Ground clearance
- Braking
- Tire configuration
- Engine output
- Transmission
- Spare parts availability
- Local road regulations
A truck mounted crane that spends most of its time working within a factory complex may require a different chassis from a machine that travels hundreds of kilometers between jobsites.
Buyers importing equipment should also check local vehicle registration and road regulations before confirming a chassis.
A crane may meet the lifting requirement but still be inconvenient if its axle loading, dimensions, emissions configuration, or vehicle documentation does not fit the destination market.
This is one reason early technical communication with the manufacturer is important.
Outriggers and Stability: A Critical Difference Between Configurations
Every lift creates forces that must be transferred safely through the crane, carrier, outriggers, and supporting ground.
As lifting capacity and working radius increase, stability becomes increasingly important.
Different truck mounted crane types may use different outrigger arrangements, spreads, and extension systems.
A buyer should understand:
- Maximum outrigger spread
- Required deployment positions
- Outrigger pad dimensions
- Ground bearing requirements
- Whether partial extension is permitted
- Whether load charts change with outrigger configuration
The ground must also be capable of supporting the imposed loads.
Soft soil, trenches, underground services, recently filled ground, slopes, drainage systems, and slab edges can all affect setup planning.
For U.S. projects, OSHA crane operating requirements provide useful official reference material covering manufacturer procedures and rated capacities. See OSHA 1926.1417.
Regardless of market, operators should follow the crane manufacturer’s instructions, applicable local regulations, and the approved lifting plan.
How to Choose the Right Truck Mounted Crane Type
When buyers contact a crane supplier, asking only:
“How much is a 10-ton truck mounted crane?”
usually does not provide enough information for a useful recommendation.
A better purchasing inquiry answers the following questions.
What will you lift?
Provide both the normal load and maximum expected load.
How far from the truck will the load be?
Working radius has a major effect on usable lifting capacity.
How high does the load need to go?
This determines boom reach requirements.
Will the vehicle also transport cargo?
If yes, cargo deck length and remaining payload become important.
What roads will the truck use?
Consider highway travel, city streets, rough access roads, industrial yards, or off-road construction areas.
How much space is available for outriggers?
Confined sites can limit the machines that are practical.
What are the ground conditions?
Concrete, asphalt, compacted gravel, soft soil, and construction fill require different setup considerations.
How often will the crane operate?
A machine used several times a month may have different priorities from one making dozens of lifts per shift.
What regulations apply in the destination market?
Vehicle rules, emissions requirements, crane standards, operator requirements, and registration procedures vary by country.
Providing these details allows the manufacturer to recommend a machine around your actual work rather than around a catalogue number.
Common Mistakes Buyers Make When Comparing Truck Mounted Crane Types
One of the most common mistakes is comparing cranes based entirely on price.
Two machines that appear similar can differ in boom construction, hydraulic components, chassis, outriggers, controls, service access, and working range.
Another mistake is choosing entirely by maximum tonnage.
Maximum capacity tells only part of the story.
Buyers also sometimes focus excessively on maximum lifting height. A crane may provide impressive reach but insufficient capacity at the radius where the customer’s heaviest lifts occur.
Ignoring the chassis is another costly mistake.
The crane and truck must work as one system.
Finally, buyers should avoid assuming that the same crane configuration is ideal for every industry.
A construction contractor, logistics fleet, electrical utility, and machinery installer can all need different characteristics even if their maximum load weights are similar.
A Practical Truck Mounted Crane Selection Table
The following framework can help narrow your options before contacting a supplier.
| Your Main Priority | Configuration to Consider | Key Specification to Verify |
| Frequent urban lifting | Compact truck mounted crane | Overall size and turning radius |
| Long vertical reach | Telescopic boom crane | Load chart at required radius |
| Loading and transporting cargo | Cargo truck with crane | Crane weight vs usable payload |
| Heavy construction | Heavy-duty truck mounted crane | Capacity, chassis and outriggers |
| Working around obstacles | Articulating/knuckle boom crane | Boom geometry and work envelope |
| Utility maintenance | Telescopic or articulating crane | Reach, mobility and setup space |
| Machinery installation | Medium/heavy telescopic crane | Fine control and capacity at radius |
| Multiple jobsites per day | Road-mobile crane truck | Travel efficiency and setup time |
This table is only a starting point.
The final machine should always be matched to a real load chart and actual operating conditions.
FAQ
What is the most common type of truck mounted crane?
Telescopic boom truck mounted cranes are widely used for construction, utility, industrial, and infrastructure lifting because they combine road mobility with useful vertical and horizontal reach.
Is a truck mounted crane the same as a mobile crane?
A truck mounted crane is a type of mobile lifting equipment, but “mobile crane” is a broader category that can include all-terrain cranes, rough-terrain cranes, crawler-related mobile equipment, truck cranes, and other configurations depending on the classification used.
What size truck mounted crane should I buy?
Choose the crane according to load weight, working radius, required height, chassis requirements, jobsite access, and duty cycle. Do not select capacity from maximum tonnage alone.
Is a telescopic crane better than a knuckle boom crane?
Neither is universally better. Telescopic cranes are often attractive for vertical reach and straightforward lifting, while knuckle boom cranes can provide compact folding and flexible positioning around obstacles.
What should I send a manufacturer before requesting a quotation?
Send your normal load weight, maximum load, working radius, required lifting height, operating environment, road conditions, preferred chassis, destination country, and expected daily workload. This helps the supplier recommend a more suitable configuration.
Conclusion
Understanding the different truck mounted crane types helps buyers move beyond simple tonnage comparisons.
The right machine is the one that matches the entire lifting task: load weight, working radius, boom reach, chassis, transport requirements, outrigger space, ground conditions, operating frequency, and local regulations.
A light-duty truck mounted crane may be ideal for frequent municipal work. A medium telescopic model may offer a better balance for general construction. A cargo truck with a crane can make sense for companies that transport and unload their own materials. Heavy-duty models are better suited to demanding infrastructure and industrial projects.
The key is to define the job first and select the crane second.
