XCT12L3

It is designed to mainly aim at domestic market, and to take international market requirements into consideration. It is mounted on a self-made special chassis, which is suitable for driving on a wide range of roads.

It has high lifting height, powerful lifting capacity and high working efficiency.  It is widely used for the lifting operations in general engineering projects, such as construction site, urban renewal, communication and transportation, ports, bridge, oilfields and mine, and complex working environments.

It is mounted on a two-axle truck crane chassis. Four-section boom with octagonal profile, a lattice jib, built-in double independent winches, new energy-saving power system, fixed counterweight and new energy-saving hydraulic system are available. The crane has newly designed XCM-G G1 appearance of Truck Crane, luxurious full-dimension driver‘s cab and XCM-G man-machine interactive system with the level of a car. Its performance takes the lead in the industry. It is more intelligent, energy-saving and user friendly to operate.

 

(1)   High performance

The four-section boom with octagonal profile is made of high strength steel. The boom can be extended up to 30.5 m, which is 1.6 m longer than the competitive products in the same class in the industry. The boom cross-section is optimized to reduce the boom torsion  and side bending during lifting operations; plug-in sliders are used to effectively increase the overlapping length of adjacent boom sections, resulting in improved lifting capacity; compact boom tail structure is designed to enhance the telescoping rate of each boom section, leading to enlarged boom length; H-type outriggers have span of 4.57 m × 5.5 m, significantly improving crane's stability; the lifting capacity of the crane is 10% higher than the highest level in the industry.

A high precision pressure shut-off valve is added to prevent pressure shock during lifting operations, to eliminate winch shaking while lowering the hook in case high temperature of hydraulic oil, greatly improving the reliability of lifting operations. A large displacement motor, combined with an oil-refilling circuit specialized for the winch and precise brake control, contributes to the response speed in millisecond and protection against winch speed out of control and prevents the load from sliding down while starting second lift.

(2)   Intelligent

The latest controltechnology platform is adopted to perform intelligent crane operations and travel control, such as automatic planning of working conditions, parameter indication such as engine rotation speed, language selector and constant speed cruise.

(3)   Energy-saving

New energy-saving hydraulic system is designed, such as the open winch hydraulic system consisting of variable displacement pumps and constant displacement motors, and the slewing hydraulic system consisting of a constant displacement pump and a low speed large torque motor with mature slewing buffering technology adopted. The external-controlled boom gravity falls results in improved lowering speed from a larger boom angle, which leads to 30% increase in the working efficiency. In addition, the radiator core fins are optimized, resulting in 10% improvement in cooling performance and 25% reduction in energy consumption for cooling.

The new power system consists of a new energy-saving engine and a transmission with synchronizer and over drive contributes to strong driving performance, high load-bearing capacity and better stability, resulting in perfect combination of high power performance and low fuel consumption, i.e.16% reduction in comprehensive fuel consumption, 12% increase in Max. travel speed

(4)  Appearance and ergonomics

The crane has newly designed XCM-G G1 appearance of Truck Crane, which looks more sturdy and elegant. The entire crane has been ergonomically improved. The full-dimension luxurious driver's cab improves driver's comfort. New designed aluminum deck presents aesthetic.

Covering door, made of new composite material, and bottom plate and handrail, made of aluminum alloy material, reduce the weight of coverings by30%~40%.

A portable reeving system is installed to reduce the reeving time from 35 min to 18 min due to no need to disassemble wedge socket.

XCM-G man-machine interactive system with the level of a car, i.e. ergonomically designed work space, informative interactive techniques and user friendly man-machine interaction are available.
