XCMG XCA350U

The XCMG XCA350U is a robust 350 US ton all-terrain crane designed for demanding lifting applications across various industries, such as construction, infrastructure, and energy projects. Its primary lifting structure comprises a 7-section, U-shaped cross-section telescoping boom, which extends from 49.2 feet to a maximum length of 262.5 feet. For added reach, the crane is equipped with a lattice jib that can be extended from 37.4 feet to 129.3 feet, with offset angles of 0°, 20°, and 40° to provide greater flexibility in lifting operations. The crane also supports a Y-guy super-lifting device, which enhances lifting capacity and reduces boom deflection during heavy lifts.

The XCA350U is powered by a Daimler OM473LA.E4-2, in-line six-cylinder diesel engine that produces 576.6 horsepower and 2,028.3 lb-ft of torque at 1,300 rpm. The engine complies with EPA Tier 4F/EU Stage 4 emission standards, ensuring reduced environmental impact while delivering strong performance. The crane’s fuel tank capacity is 118.9 gallons, allowing for extended operational periods. An auxiliary Daimler OM936LA.E4/3 engine is used for the superstructure, delivering 281.6 horsepower for dedicated lifting tasks.

The crane is equipped with a ZF electronic-controlled transmission system featuring six forward gears and one reverse gear, providing smooth operation across a variety of terrains. The crane’s high-strength axles, supplied by KESSLER, offer reliable performance with pneumatically controlled drum brakes. The hydro-pneumatic suspension system provides automatic leveling and shock absorption, with adjustable stroke to optimize stability for both on-road and off-road conditions.

The XCA350U’s outriggers are arranged in an H-shaped configuration and can be extended to four positions: fully retracted, half-extended, 75% extended, and fully extended. Hydraulic controls and pressure detection systems ensure safe and stable setup on different job sites. The crane’s advanced hydraulic system features a twin-variable displacement pump that powers all key functions, such as hoisting, slewing, and telescoping. This system allows precise and efficient load handling, even at low speeds, with stepless speed regulation for smooth crane movements.

Safety is a critical aspect of the XCA350U’s design. It comes with a dual-circuit air pressure braking system, auxiliary engine retarder brakes, and various electronic safety devices, including a load moment indicator (LMI), hydraulic balance valves, and anti-two block systems to prevent rope over-winding. The cab design further enhances operator safety and comfort, featuring large arc glass windows for better visibility, a 20° tiltable structure for high-angle lifts, and a fully adjustable seat with climate control. A 10.4-inch touchscreen display provides real-time monitoring and control of crane operations.

The crane’s slewing system features a four-point ball contact ring with a planetary gear reducer, allowing for 360° continuous rotation. Power control and free slewing modes are available to optimize crane positioning and operation during complex lifts. Additionally, the XCA350U supports multiple steering modes, including all-axle steering and crab steering, to improve maneuverability on tight or rough job sites.

Overall, the XCMG XCA350U combines significant lifting power, advanced technology, and versatile configurations to meet the demands of heavy lifting projects in challenging environments.
