QRY sequence of rough terrain crane is a type of telescopic increase and swing sort crane which travels with tire type chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting part, composed of the telescopic boom, 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 linked by the slewing bearing.
Major attributes:
one) Front-wheel steering, rear-wheel steering, 4-wheel steering and cab steering, all-wheel drive, off-road overall performance, suited for off-freeway journey.
two) All functions can be extended outriggers, semi-extend outriggers perform, all reduced outriggers work, outriggers work and do not flight traffic load.
three) Suited for slender area travel and operations small turning radius strong maneuverability.
four) Risk-free and trustworthy manage program, two-seats, all-directional lifting procedure, significantly enhanced the capability of the entrance lifting operation.
5) The crane has good visitors-capability, dynamic performance and mobility, and is ready to function in every single course and journey while hoisting without having outriggers. The merchandise is commonly employed in weighty lifting functions, limited-distance transfer, slender-website lifting operations for building web sites, out of doors oilfields, warehouses, freight yards, logistics basses and other internet sites.
Security unit:
Basic safety unit includes torque limiter, swing desk lock unit, winch more than-winding and over-leisure safeguard unit, outrigger lock unit, outrigger bidirectional hydraulic lock, Rear axle steering lock and rear wheel return detector, unexpected emergency steering energy device, gradienter, hydraulic technique overflow valve, balance valve.
1) Torque limiter
Detecting purpose: Detect the angle of the growth immediately.
Display purpose: Display working info such as real load, managing radius, boom angle.
Caution function: When the actual load exceeds rated lifting load, Torque limiter will give an alarm and cease the operation.
two) Swing table lock gadget
During the driving approach, a plug gadget is utilised to connect the swing desk and the carrier to hold the steering parts (swing desk, increase) from swing brought on by inertia.
3) Winch above-winding protect device
When the load reaches a specific peak, torque limiter will stop the slipping and indicating gentle on the instrumentation board will be on.
4) Winch more than-relaxation shield device
When only 3 laps of rope is left on the winch, torque limiter will stop the falling and indicating gentle on the instrumentation board will be on.
5) Outrigger lock gadget
During the driving approach, a plug device is utilized. By plugging the outrigger, the gadget deeps it from extending.
6) Outrigger bidirectional hydraulic lock
Outrigger bidirectional hydraulic lock is utilised to hold the two horizontal and vertical cylinder form retraction.
seven) Rear axle steering lock and rear wheel return detector
During the driving method, only entrance axle steering is essential and the rear ought to be returned aligned. For this purpose a lock gadget is utilized and indicating mild on the instrumentation board exhibits the status.
8) Crisis steering energy gadget (crisis pump)
If there is an unexpected emergency that the motor can’t be started, the crane can be dragged by other cars. The unexpected emergency pump is pushed by battery and provides electricity to energy cylinder.
