Features and advantages of XCT12L4 Truck crane

XCT12L4 Truck crane 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 XCMG G1 appearance of Truck Crane, luxurious full-dimension driver’s cab and

XCMG 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.

We reserve the right to modify the design without notice for improvement.

(2) Intelligent

The latest control technology 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 fall

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 XCMG 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 improve driver's comfort. New designed aluminium deck presents

aesthetic.

Covering door, made of new composite material, and bottom plate and handrail, made of

aluminium alloy material, reduce the weight of coverings by 30%~40%.

A portable reeving system is installed to reducethe the reeving time from 35 min to 18 min

due to no need to disassemble wedge socket.

XCMG 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.
