XCMG XCT90 Load Chart PDF + Specifications

The XCMG XCT90 hydraulic truck crane is engineered as a high-performance mobile lifting solution in the 90-ton capacity class, integrating advanced structural design, efficient hydraulic systems, and intelligent electronic control technologies. Introduced in the mid-2010s as part of XCMG’s updated XCT series, the crane reflects the manufacturer’s focus on improved lifting performance, operational precision, and energy efficiency.

The crane is mounted on a four-axle truck chassis designed and manufactured by XCMG. The chassis features an 8×4×8 drive and steering configuration, meaning axles 1 and 2 provide steering while axles 3 and 4 handle both driving and steering functions, enabling excellent maneuverability in confined job sites. The chassis frame is constructed from high-strength steel with an optimized load-bearing box-type structure that improves torsional rigidity and durability. Overall dimensions of the crane are approximately 13.99 m in length, 2.78 m in width, and 3.99 m in height, with a traveling weight of about 48 tonnes.

Two diesel engine options are available for the chassis powerplant. One option is the MC11.40-50 engine from China National Heavy Duty Truck Group, delivering 297 kW at 1900 rpm with a displacement of 10.518 liters and torque reaching 1900 Nm between 1000 and 1400 rpm. The alternative is the Weichai WP12.375E50 engine, producing 276 kW at 1900 rpm, with 11.596 liters displacement and 1800 Nm torque within the same speed range. Both engines comply with China V emission standards and are paired with a Fast Gear 10JSD180TB mechanical transmission providing 10 forward and 2 reverse speeds. With this drivetrain configuration, the XCT90 achieves a maximum road speed of 90 km/h and a maximum gradeability of 45%, enabling efficient transportation between work sites.

The crane’s superstructure hydraulic system employs an electric proportional variable piston pump driven by the engine, providing precise control for lifting, slewing, telescoping, and boom elevation. The system uses electro-hydraulic proportional control valves and an air-cooled hydraulic oil cooler to maintain stable operating temperatures. The hydraulic oil tank has a capacity of approximately 840 liters, ensuring reliable performance during continuous lifting operations.

The main lifting structure consists of a six-section U-type telescopic boom fabricated from high-strength structural steel. The boom extends from 12.4 m to a maximum of 58 m, utilizing a single-cylinder pinning telescoping system that allows flexible boom combination and improved telescoping efficiency. Full extension of the boom to its maximum length requires approximately 450 seconds. When combined with the lattice jib system, the crane’s lifting height can reach 75 m, or up to 82 m with optional inserts. The jib itself can be configured in lengths of 10.8 m, 18.3 m, or 25.3 m, with offset angles of 0°, 15°, and 30°, enabling operation in various lifting geometries.

Lifting operations are performed using hydraulically driven planetary gear winches. The main winch delivers a single line pull of 82 kN with a maximum line speed of 135 m/min, while the auxiliary winch provides 71.5 kN single line pull and 105 m/min line speed. Both winches are equipped with balanced valves and normally closed brakes for safe load control. The crane typically uses a 20 mm diameter wire rope, with lengths up to 260 m on the main winch and 180 m on the auxiliary winch.

The slewing mechanism uses a single-row four-point contact ball bearing slewing ring with external gear teeth, driven by a hydraulic motor through a planetary reduction gear. This arrangement allows continuous 360-degree rotation with a maximum slewing speed of about 1.8 rpm. Slewing speed can be infinitely regulated, providing smooth and precise movement during lifting operations.

Stability during lifting is ensured by four fully hydraulic outriggers arranged in a K-type configuration. The outriggers extend to provide a span of approximately 7.95 m longitudinally and 7.9 m laterally, significantly increasing stability during heavy lifts. The outrigger float diameter is 450 mm, and the system is capable of supporting a maximum reaction force of approximately 820,000 N at full lifting load.

The crane is equipped with multiple safety and control systems designed to improve operational reliability. These include hydraulic balance valves, relief valves, two-way hydraulic valves, and an anti-two-block device that prevents over-hoisting of the hook. A Hirschmann Load Moment Indicator (LMI) system continuously monitors load conditions and automatically warns the operator when approaching overload situations. The system also records overload events and provides fault diagnostic functions.

The operator’s cab is fully enclosed and designed for ergonomic comfort, featuring a wide-view windshield, adjustable seat with armrest-mounted joysticks, and well-arranged control instruments. The cab also includes safety glass windows, sun shields, and integrated monitoring displays. The driver’s cab on the chassis side is similarly designed with comfort features such as air conditioning, electric mirrors, and air-suspension seating.

Overall, the XCMG XCT90 combines strong lifting performance, efficient hydraulic technology, and intelligent control features within a highly mobile four-axle truck crane platform. Its capability to deliver a maximum lifting capacity of 90 tonnes, together with long boom reach and excellent road mobility, makes it suitable for a wide range of heavy lifting tasks in construction, infrastructure development, energy projects, and industrial installation work.
