The XCT90U is a 90Ust hydraulic truck crane newly developed for the North American market. It features a compact structure, good travel performance, great lifting capacity, and a wide scope of operations. The power platform is based on the US-made Cummins engine, which complies with the EPA13 emission standards. The torque limiter system satisfies the world's most stringent EN13000 torque limiter control requirements, ensuring its reliable safety performance.
Lifting Performance: The five-section U-shaped arm has a length range of 39.4-147.6 ft. The fully extended arm is longer than the industry average by 3.3 ft, providing performance greater than other manufacturers by 5%-10%.
With the dual-cylinder telescopic rope arranging system, it takes 140 seconds for the Boom to be fully extended, which is highly efficient and shortens job preparation time.
The electric load-sensitive multi-way valve, with smoother linear gradient of throttle opening, provides precise flow control, smooth operation, and good micro-mobility.
The pump control swing system is equipped with the US Eaton electronic proportional displacement pump, providing good swing micro-mobility and smooth movement.
Safety and Reliability
The multi-mode unloading control strategy complies with 62 EN13000 safety requirements and ensures comprehensive operation safety.
The high-performance lifting system, coupled with the proprietary auxiliary fuel supply system, ensures the lifting system stability and reliability and effectively prevents motor stall.
Safety features such as swing brake pressure test, accumulator pressure-holding, and low-pressure alarm effectively enhance operation safety.
The working lights and 3-color warning lights adopt LED light source to ensure the safety of other people on the work site.
Ease of Use
The centralized pressure measurement and display system provides real-time monitoring of system pressure so that any faults are detected and dealt with in a timely manner.
The optimized combination of cover panels facilitates removal and installation and enhances the serviceability of key elements or wearing parts.
The hydraulic system assists the mounting of the combined counterweight system, greatly improving convenience and efficiency.
The slide-door control cab and the front and side pedals inside are extremely user-friendly.
The deluxe cab provides extra-large storage room, and the air suspension heated seat, electric heated rear-view mirrors, and all-in-one AC system improve ride comfort.
