The XCMG QY50K5D_3 50 ton truck crane is a heavy-duty mobile lifting machine designed for construction, infrastructure, industrial installation, and other medium-to-heavy lifting operations. With a maximum lifting capacity of 50 tons, a five-section telescopic boom extending to 44 meters, and a maximum lifting moment of 1600 kN·m, this truck crane combines substantial lifting capability with practical road mobility. XCMG describes the model as a compact truck crane suitable for applications including factory construction, urban reconstruction, and regular job-site operations.

Its combination of lifting performance, road speed, compact dimensions, and hydraulic control makes the QY50K5D_3 suitable for contractors and equipment users who need one machine to travel between different work locations while handling demanding lifting tasks.

XCMG QY50K5D_3 at a Glance

The QY50K5D_3 is built around a truck-mounted crane configuration, allowing the machine to travel between work sites without requiring a separate transportation vehicle for every relocation.

The XCMG official product page also lists a 50-ton maximum rated lifting capacity, 44-meter main boom, 1600 kN·m maximum lifting moment, 90 km/h maximum travel speed, and 45% maximum gradeability.

1. 50-Ton Lifting Capacity for Diverse Jobs

The most important characteristic of the QY50K5D_3 is its 50-ton maximum lifting capacity.

This capacity places the crane in a useful range for many construction and industrial lifting operations. It can be used for handling structural components, machinery, construction materials, equipment modules, and other heavy loads when the required load chart and working radius are within the machine's rated limits.

It is important to understand that a 50-ton rating does not mean the crane can lift 50 tons at every boom length or working radius. Actual lifting capacity depends on factors such as:

• Working radius

• Boom length

• Boom angle

• Outrigger configuration

• Counterweight configuration

• Ground conditions

• Load position

Operators should always follow the manufacturer's load chart and operating instructions for the specific lifting condition.

2. Five-Section Telescopic Boom

The QY50K5D_3 uses a five-section telescopic main boom with a maximum length of 44 meters.

This design gives the crane greater flexibility when working at different heights and radii. A shorter boom configuration can be useful for closer, heavier lifting operations, while extending the boom allows the crane to reach farther working positions.

The supplied main boom range is 11.3 to 44 meters, providing operators with multiple boom configurations according to the job requirements.

The official XCMG description highlights the five-section 44-meter main boom as one of the machine's main features.

3. Additional 9-Meter Jib

For applications requiring additional reach or lifting height, the crane can be equipped with a 9-meter jib.

The combination of the main boom and jib expands the machine's working envelope and makes it more useful for tasks involving elevated structures or loads positioned away from the crane's center.

According to available product information, the QY50K5D_3 can achieve a maximum lifting height of approximately 52.2 meters under the specified configuration.

This makes the crane suitable for various building construction and structural installation applications where a standard boom configuration may not provide sufficient vertical reach.

4. 1600 kN·m Maximum Lifting Moment

The 1600 kN·m maximum lifting moment is another important performance indicator.

Lifting moment reflects the relationship between load and working radius. As the working radius increases, the available lifting capacity normally decreases.

For buyers evaluating a 50-ton truck crane, looking only at maximum lifting capacity can therefore be misleading. The lifting moment and load chart provide a better understanding of how the crane performs across different working conditions.

The QY50K5D_3's 1600 kN·m maximum lifting moment provides a strong foundation for medium- and heavy-duty lifting applications. XCMG lists this figure as one of the model's principal specifications.

5. SC9DF340Q6 Engine Provides Strong Road Performance

The truck crane is equipped with an SC9DF340Q6 engine.

The supplied specification lists:

• Engine power: 251 kW at 1900 rpm

• Maximum torque: 1490 Nm

This powertrain is important not only when the crane is traveling between work sites but also when operating in areas with gradients or difficult road conditions.

The maximum travel speed is specified at 90 km/h or higher, while gradeability is listed at 45% or higher.

XCMG similarly identifies the machine's 340-horsepower-class 9-liter engine and 90 km/h maximum travel speed as important features for road mobility.

6. Compact Dimensions Improve Site Access

One of the notable characteristics of the QY50K5D_3 is its compact truck-mounted design.

XCMG states that the machine has an overall height of approximately 3.48 meters and a vehicle width of about 2.65 meters. The manufacturer specifically highlights its suitability for bridges, culverts, tunnels, and narrower roads.

This can be particularly useful for contractors working in urban areas.

Large lifting equipment can sometimes have excellent lifting capacity but become difficult to move through restricted access routes. A relatively compact truck crane can provide a better balance between lifting performance and transportation convenience.

7. H-Type Outriggers for Working Stability

Once the crane arrives at the job site, stability becomes a major consideration.

The QY50K5D_3 uses H-type outriggers, with the supplied outrigger span listed as approximately 6.075 × 7.35 meters.

When properly deployed on suitable ground, outriggers provide a broader support base for lifting operations.

The actual setup still needs to follow the manufacturer's operating procedures. Ground bearing capacity, outrigger positioning, leveling, load chart requirements, and surrounding obstacles should all be evaluated before lifting.

8. Hydraulic System Designed for Precise Control

Lifting performance is not only about capacity. Operators also need to control the load accurately.

XCMG states that the QY50K5D_3 uses proprietary double-pump automatic flow-dividing and combining hydraulic technology, together with multi-stage buffer control. The manufacturer says these technologies improve control and micro-motion performance and support smoother starting and stopping during slewing operations.

This type of control is particularly useful when positioning loads accurately.

For example, during steel structure installation or equipment placement, the operator may need to move the load slowly into a precise position rather than simply raising or lowering it quickly.

9. Suitable Applications

The QY50K5D_3 can serve a variety of construction and industrial applications.

Building Construction

The crane can be used for lifting structural components, machinery, building materials, and other construction loads.

Steel Structure Installation

Steel beams and structural assemblies often require controlled lifting and positioning. The combination of boom reach and lifting moment can make the QY50K5D_3 suitable for many steel structure projects within its rated capacity.

Bridge and Infrastructure Projects

Its compact dimensions and relatively narrow vehicle width can be advantageous when working around bridges, roads, and infrastructure projects.

Urban Reconstruction

Urban construction often presents limited working and transportation space. The QY50K5D_3's compact design can help it access locations where larger cranes may face greater restrictions.

Factory Equipment Installation

Factories frequently need cranes to move heavy machinery, production equipment, and structural components during installation, relocation, or maintenance.

XCMG lists factory construction, urban reconstruction, and job-site rental operations among the model's applicable working conditions.

10. Why Choose a 50-Ton Truck Crane?

A truck crane can provide a practical balance between lifting capability and mobility.

Compared with equipment designed primarily for stationary lifting, a truck crane can travel between locations using its road-going chassis.

For contractors handling multiple projects, this can reduce the logistical complexity associated with moving lifting equipment from one site to another.

The QY50K5D_3 is particularly suited to users who need:

• Up to 50-ton rated lifting capacity

• Long telescopic boom reach

• Additional jib capability

• Strong road mobility

• Compact dimensions

• Wide working coverage

• Precise hydraulic control

• Multi-site operating flexibility

The XCMG QY50K5D_3 50 ton truck crane combines a 50-ton maximum lifting capacity, five-section 44-meter telescopic boom, 9-meter jib, 1600 kN·m maximum lifting moment, and 251 kW engine into a mobile lifting platform designed for demanding construction and industrial applications.

Its compact dimensions, H-type outriggers, strong road performance, and hydraulic control technology make it particularly interesting for contractors working across construction sites, urban projects, infrastructure development, steel structure installation, and factory equipment handling.

For any lifting project, however, the machine must be selected and operated according to the applicable load chart, working radius, ground conditions, configuration, and local safety requirements. The headline 50-ton capacity should always be evaluated together with the actual lifting conditions rather than treated as a universal working capacity.
