Features and advantages of XCT55（L type） Truck Crane

XCT55 truck crane is

designed mainly for domestic

market including international

market, which meets the

demands in different areas by

means of variable and selectable

configuration. It is widely used

in many complicated jobsites

such as constructions, urban

renovation, transportation, port, bridge, oil and mining etc.

With four-axle crane chassis, K-shaped outrigger and new single cylinder slotting system,

XCT55 (L type) has six-section boom added with two lattice jibs, concealed double-independent

winches and a combined counterweight. Equipped with new energy-saving hydraulic system, it

adopts intelligent lattice technology supporting multi--jobsite detecting functions, which results

in more convenient operation. With XCMG G-generation brand new design and man-made

interactive system reaching the level of car, XCT 55(L type) takes the lead of the highest

performance in the industry which contributes to more intelligent, energy-saving and humanized.

(1) High Performance

Five-section boom with U-shaped profile optimizing the proportion of height and width is

made of imported high tension steel material which can reduce boom torsion and side-bending.

Inserted sliders may efficiently increase the overlapping length of adjacent boom sections,

eliminating the point contact or line contact between slider and boom while the boom is lifting a

load and avoiding effectively local buckling phenomenon. Compact tail boom effectively

increases the overlapping length and improves the capacity of boom for anti-bending and

torsion-resistant. Single-board boom tip further increases the overlapping length with high

hoisting performance and optimized structural member weight.

New single cylinder slotting telescoping system researched on the latest telescoping theory

contributes to more compact structure with six-section boom of 50m that breaks the limitation of

five-section boom below 50t.

(2) Intelligent operation and convenient safety

Originally designed and intelligent boom technology provides customers comfortable and

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

2015年08月版

intelligent operating experience.

Automatic planning of working conditions: If users enter the information about lifting load

and distance, the system will automatically recommend the.properest working conditions, which

may meet lifting demands.

Automatic compensation of hoisting system: the winch can be spooled in and out

automatically when telescoping and elevating, which can reduce driver’s operation difficulty,

save over 40% of operation time and greatly improve the safety and working efficiency.

Automatic elevating compensation: by controlling elevating angle, the crane can

automatically compensate the elevating change due to boom deflection when hoisting the hook.

Thus, the problem of boom run-out can be solved which can improve the reliability and reduce

hoisting difficulty within operation.

(3) Energy-saving, environment-friendly and economical

New energy-saving hydraulic system includes the lifting hydraulic system consisting of

variable displacement pump and constant displacement motor and the slewing hydraulic system

consisting of constant displacement pump and constant displacement motor with low-speed large

torque. Mature slewing buffering technology is applied. The external-controlled power lowering

boom combined with gravity fall results in increased lowering speed from a larger boom angle,

improving working efficiency more than 30%. New-generation intelligent control hydraulic

system with independent radiator contributes to real-time control of radiator switch as well as the

increased rotary speed of radiator in idling speed of engine. Meanwhile, optimized core radiator

improves more than 30% of heat dissipation capacity and reduces 25% of heat dissipation rate.

With low speed and large torque engines and high ratio, overdrive gearbox as the core of a

new power platform, XCT 55 has a strong driving performance, large quantity of load capacity,

good stability, which can achieve a high dynamic performance with low fuel consumption

reduced by 12% and driving performance improved by 15%.

First released energy recycle technology can recover and reuse the power energy from

braking. The speed can reach 30km/h when starting for 5.3s and grade ability improved by 5%.

（4）High reliability

High-precision variable displacement pump and control valve of electro-hydraulic

proportional equipped with constant winch of large displacement have the ability to prevent the

pressure impact within operation and to eliminate shaking in high temperature which improves

the reliability of lifting operations. A large displacement motor combined with an oil-refilling

hydraulic circuit for winch and precise brake control contributes to the response speed in

millisecond, consequently preventing load sliding down during secondary lifting operation.

(5) Brand new experience of man-made interactive design and appearance

Designed with XCMG G-generation truck crane, the steady and elegant XCT 55 combines

man-made mechanisms that comprehensively promote the humanization matching air suspension

in driver’s cab with low noise. More comfortable driving performance can be achieved equipped

with new deck made of aluminum and more elegant appearance.

Made of new combined material, the hood is shaped from models with good appearance.

The board and assist grip are made of aluminum alloy reducing the hood height by 30%-40%.

New design of virtual dashboard interface makes clear display of vehicle information.

For slewing locking mechanism, it is manipulated by flexible shaft control with which the

slewing can be locked and started in operator’s cab.

XCMG man-machine interactive system with the level of car: working space is designed

according to ergonomics and

13 items of intelligentize and informatization interactive

technology are integrated, which brings more friendly man-machine conversation. Added super

structural passage satisfies the functional demands which can reach the area of winch and boom.
