XCMG 20 Ton XCT20L4 4-section Boom Mobile Truck Crane Lifting
Height 43.2m
XCT20 Truck Crane is an efficient, economic and applicable brand
new product designed on basisof XCMG G generation R&D platform.
With 3-axle self-made special chassis, 4-section boom, built-in
double independent winch and power system with low speed and large
torque, this crane has industry-leading lifting height, lifting
capacity and working efficiency.
Integrated with new energy-saving hydraulic system, mature engine
system of Shanghai Diesel Engine and WeichaiEngine, all covering
walking surface and XCMG man-machine interactive system with the
level of car provides more options for customers and bring more
comfortable driving and operation experience. XCT20 Truck Crane is
widely suitable for construction site, urban renewal, traffic
transportation, port,bridge, oil field, mine field and othercomplex
working environment. It has industry-leading performance.
(1) 360° full slewing operation and powerful lifting performance
Optimized matching of whole crane according to multi-body dynamics
is adopted, reasonable arrangement and optimum appliedforce.
With 4-section 'U'crosssection of boom adopted, boom length is 34m,
jib length is 8.3m, leading in the high level of industry; With 5
jack equipped, 360° full slewing operation is realized.
(2) New energy-saving hydaulic system contributes to smooth
manipulation, perfect fine control and high working efficiency
Exclusive matching throttle with compensation afterwards and
load-sensitive technology results in the higher stability of the
lowest system flow, more reasonable system rigidity, more
outstanding fine control and smoothness. With double pump
confluence of hoisting, elevating and telescoping, the working
speedof main and auxiliary winch can reach135m/min, which improves
the working efficiency greatly. The distribution of flow in
actuators is more optimized when conducting compound movements and
the working efficiency is more outstanding.
(3) Integrated PLC control system contributes to higher reliability
of products and more convenient maintenance
Since the electric system is updated to PLC control system with new
class cable harness ofhigh protection, the circuit branches become
less owing to the cable harness branch design of various passages.
Fault elimination in the bottom layer improves the reliability.
The combination design of controller, display and GPS integration
with waterproof connector clips enhances the system reliability.
With self-diagnosis functions of errorsin control system,the fault
elimination becomes more convenient as well as the maintenance.
