QRY series of rough terrain crane is a variety of telescopic increase and swing kind crane which travels with tire variety chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting component, composed of the telescopic growth, jib, principal winch, aux. winch, luffing system, counterweight, swivel table, and so on. The undercarriage is composed of the suspension and wal ept part. The superstructure and the undercarriage are related by the slewing bearing.
Primary functions:
1) Entrance-wheel steering, rear-wheel steering, four-wheel steering and cab steering, all-wheel travel, off-road performance, suitable for off-freeway vacation.
2) All operations can be extended outriggers, semi-stretch outriggers work, all diminished outriggers function, outriggers operate and do not flight site visitors load.
3) Ideal for slender area vacation and operations modest turning radius robust maneuverability.
4) Secure and trustworthy manage program, two-seats, all-directional lifting operation, greatly improved the ability of the entrance lifting operation.
5) The crane has great traffic-capability, dynamic performance and mobility, and is able to function in every direction and travel although hoisting without having outriggers. The merchandise is commonly utilised in large lifting operations, limited-length transfer, slim-website lifting functions for design websites, outdoor oilfields, warehouses, freight yards, logistics basses and other sites.
Safety device:
Protection device contains torque limiter, swing desk lock system, winch more than-winding and in excess of-leisure safeguard gadget, outrigger lock gadget, outrigger bidirectional hydraulic lock, Rear axle steering lock and rear wheel return detector, unexpected emergency steering electricity device, gradienter, hydraulic program overflow valve, stability valve.
1) Torque limiter
Detecting operate: Detect the angle of the growth immediately.
Display purpose: Show functioning info this kind of as actual load, dealing with radius, boom angle.
Caution operate: When the real load exceeds rated lifting load, Torque limiter will give an alarm and cease the operation.
two) Swing table lock device
During the driving approach, a plug device is utilised to hook up the swing desk and the provider to maintain the steering areas (swing desk, boom) from swing induced by inertia.
three) Winch in excess of-winding shield system
When the load reaches a specific top, torque limiter will end the slipping and indicating light-weight on the instrumentation board will be on.
four) Winch more than-peace defend unit
When only 3 laps of rope is still left on the winch, torque limiter will cease the falling and indicating light-weight on the instrumentation board will be on.
5) Outrigger lock gadget
During the driving process, a plug unit is utilised. By plugging the outrigger, the gadget deeps it from extending.
six) Outrigger bidirectional hydraulic lock
Outrigger bidirectional hydraulic lock is used to preserve both horizontal and vertical cylinder kind retraction.
7) Rear axle steering lock and rear wheel return detector
During the driving procedure, only entrance axle steering is needed and the rear need to be returned aligned. For this cause a lock unit is used and indicating mild on the instrumentation board exhibits the standing.
eight) Emergency steering electrical power gadget (unexpected emergency pump)
If there is an unexpected emergency that the engine can’t be started, the crane can be dragged by other automobiles. The crisis pump is pushed by battery and supplies electrical power to energy cylinder.
