QRY50 tough terrain crane is a sort of telescopic growth and swing kind crane which travels with tire type chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting portion, composed of the telescopic boom, jib, major winch, aux. winch, luffing system, counterweight, swivel desk, and so forth. The undercarriage is composed of the suspension and wal ept part. The superstructure and the undercarriage are related by the slewing bearing.
one. Entrance-wheel steering, rear-wheel steering, four-wheel steering and crab steering, all-wheel drive, off-highway
Performance, suited for off-freeway vacation.
two. The axle adopts KESSLER+CO (Germany), with axle differential lock.
3. The gearbox adopts ZF model or Dana model (Optional)
four. The brake system is imported from American Mico company
5. Completely prolonged outriggers operation, with semi-stretch outriggers operation, without outriggers operation and traveling with load operation can be understood.
six. Suited for slim area journey and operations little turning radius sturdy maneuverability.
seven. Secure and reputable handle method, two seats or one seat can be optional, all-directional lifting operation, tremendously increased the capacity of the entrance lifting.
8. The crane has very good targeted traffic-potential, dynamic overall performance and mobility, and is able to run in every single route and journey although hoisting without outriggers. The product is broadly utilised in weighty lifting operations, short distance transfer, narrow-internet site lifting operations for design sites, outside oilfields, warehouses, freight yards, logistics basses and other web sites.
Basic safety unit:
Basic safety unit includes torque limiter, swing desk lock device, winch in excess of-winding and more than-relaxation protect gadget, outrigger lock system, outrigger bidirectional hydraulic lock, rear axle steering lock and rear wheel return detector, emergency steering electricity device, gradienter, hydraulic system overflow valve, balance valve.
1) Torque limiter
Detecting operate:Detect the angle of the growth routinely.
Display purpose: Present functioning information such as genuine load,dealing with radius,boom angle.
Caution function:When the genuine load exceeds rated lifting load,Torque limiter will give an alarm and end the
2) Swing table lock unit
During the driving method,a plug device is employed to join the swing table and the provider to hold the steering parts (swing table, boom) from swing induced by inertia.
3) Winch in excess of-winding defend gadget
When the load reaches a certain peak,torque limiter will cease the falling and indicating light on the instrument
panel will be on.
four) Winch more than-peace shield device
When only 3 laps of rope is still left on the winch,torque limiter will cease the slipping and indicating light on the
instrumentation board will be on.
five) Outrigger lock system
During the driving process,a plug gadget is utilized.By plugging the outrigger,the device deeps it from extending.
6) Outrigger bidirectional hydraulic lock
Outrigger bidirectional hydraulic lock is employed to insure the horizontal and vertical cylinder will not
automatically retract when outriggers are in the extending point out .
seven) Rear axle steering lock and rear wheel return detector
During the driving process,only entrance axle steering is needed and the rear need to be returned aligned.For this
reason a lock system is utilized and indicating light-weight on the instrumentation board shows the status.
8) Emergency steering power system (crisis pump)
If there is an emergency that the motor can not be commenced, the crane can be dragged by other cars. The
emergency pump is driven by battery and provides electricity to energy cylinder.
