The 220t telescopic crawler crane with the best performance in the world.
Seven-section boom of 73 m, 108.2 m maximum length of boom plus jib, widest working range and best lifting capacity; three innovative limit construction techniques, supplying best solution for applications in job sites with confined space and relatively small ground bearing capacity.
Seven-section boom of 73 m, jib of 44 m, 108.2 m maximum combined length is available, longest combined length in its class, comprehensive lifting performance leads by 5% ~ 10% in the industry.
FLEXIBLE, STRONGER CONSTRUCTION ADAPTABILITY
Three innovative limit construction techniques, supply best solution to overcome the engineering construction limitation in extremely harsh environ-ment conditions and create the great convenience for the construction application.
1.0~30°lifting technology, makes the crane ideal for work in ultra-low spaces with a height of 5 m;
2. Narrow track 360°lifting technology, max. width of 4.5 m, better pass ability;
3.Various-counterweight configuration lifting technology, leads to more working
conditions, less ground pressure, more economical to use.
INSTALLATION,REMOVAL AND TRANSPORT, EFFICIENT AND ECONOMICAL
More efficient self-removal function of crawler beam and counter-weight, greatly reduces operating cost;
The machine can be operated by remote control, safer and more convenient;
Transport weight of heaviest single unit is 31 t and transport width is or less than 3 m, compliant with the worldwide transportation regula-tions, leading in the industry.
NEW INDUSTRIAL DESIGN, NEW OPERATION EXPERIENCE
New industrial design, fashionable appearance of operator's cab, a perfect combination of streamlining and strength, presentation of power and vigor, comprehensive ergonomic design and personalized consideration of details,lead to more comfortable operating environment, wider vision, easier maintenance and new operation experience.
Safety Devices
Safety device includes:
XGC220T telescopic crawler crane widely uses mechanical, electronic,hydraulic and other safety and waming devices, in order to ensure the safe operation of machine. The safety devices include: load moment limiter,main/auxiliary winch over-wind protection device, main/auxiliary winch over-release protection device. emergency stop switch, slewing lock device, pilot control switch, closed circuit monitoring system, buzzer, waming light, height mark lamp, anemometer, electronic level meter, block bax function, hydraulic system overflow valve. balance valve, hydraulic lock, and etc.
Lode moment limiter
Detection function: automatically detect boom angle and lifting weight.
Display function: real time display current actual load, working radius, boom angle and wind speed.
Warning function: automatically send out warning and stop crane operation when detecting the actual load exceeds the rated load or boom angle exceeds the limit value.
Main/Auxiliary winch over-wind protection device
When main/auxiliary winch hoists up to the maximum height, height limit detection switch works and an over-wind warning lamp on instrument panel lights on, at the same time, load moment limiter stops crane hoisting up
operation.
Main/Auxiliary winch over-release protection device
When the rope end limiter switch on winch drum detects that only three turns of wire rope are left on the drum, the indicatior lamp on the instrument lights up, at the same time, load moment limiter stops crane hosting down operation. In emergency conditions, press the switch to stop the engine and all the crane movements.
Slewing lock device
Pin shaft type mechanical lock, the crane can be locked over front or back directions.
Pilot control switch
After pressing the switch, the electrical system of liftig operation can be operated normally.
Hydraulic system
Hydraulic system is equipped with hydraulic balance valve, hydraulic overflow valve and two-way hydraulic lock to ensure the stability and safaty of system working.
Tricolor warning lamp
The lamp comprises 3 colors, when crane loading is below 90%,"Green Lamp" lights on to indicate that the crane is nunning in safety area; when crane loading is 90%-100%,"Yellow Lamp" lights on to indicate that the crane is close to the rated lifting load; when crane loading is above 100%,“Red Lamp' and "Yellow lamp" light on at the same time to indicate that the crane is overloaded and in dangerous area, the control system willautomatically cut off the crane movement toward dangerous direction.
