Product Description

Introduce :
QRY 50 rough terrain crane is a kind of telescopic boom and swing type 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, main winch, aux. winch, luffing mechanism, counterweight, swivel table, etc. The undercarriage is composed of the suspension and walking part. The superstructure and the undercarriage are connected by the slewing bearing.
Main features :
1. Front-wheel steering, rear-wheel steering, four-wheel steering and c r ab steering, all-wheel  drive, off-road  
   Performance , suitable for off-highway travel.
2. The axle adopts KESSLER+CO  (Germany) , with axle differential lock.
3. The gearbox adopts ZF brand or Dana brand (Optional)
4. The brake system is imported from American Mico company
5. Fully extended outriggers  operation , with semi-stretch outriggers  operation, without  outriggers  operation and traveling with load operation can be realized .
6. Suitable for narrow space travel and operations; small turning radius; strong maneuverability.
7. Safe and reliable control system, two  seats  or one seat can be optional , all-directional lifting operation, greatly enhanced the ability of the front lifting .
8. The crane has good traffic-ability, dynamic performance and mobility, and is able to operate in every direction and travel while hoisting without outriggers. The product is widely used in heavy lifting operations, s hort  distance transfer, narrow-site lifting operations for construction sites, outdoor oilfields, warehouses, freight yards, logistics basses and other sites.
 
Safety device :
Safety device includes torque limiter,  swing table lock device,  winch over-winding and over-relaxation  protect device,  outrigger lock device,  outrigger bidirectional hydraulic lock,  r ear axle steering lock and rear wheel return detector,  emergency steering power device,  gradienter,  hydraulic system overflow valve,  balance valve.
1) Torque limiter
 Detecting function:Detect the angle of the boom automatically.
 Display function: Show operating information such as actual load,handling radius,boom angle.
 Caution function:When the actual load exceeds rated lifting load,Torque limiter will give an alarm and stop the  
 operation.
2) Swing table lock device
  During the driving process,a plug device is used to connect the swing table and the carrier to keep the steering p arts  (swing table,  boom)  from swing caused by inertia.
3) Winch over-winding protect device
  When the load reaches a certain height,torque limiter will stop the falling and indicating light on the instrument
  panel  will be on.
4) Winch over-relaxation protect device
  When only 3 laps of rope is left on the winch,torque limiter will stop the falling and indicating light on the
  instrumentation board will be on.
5) Outrigger lock device
  During the driving process,a plug device is used.By plugging the outrigger,the device deeps it from extending.
6) Outrigger bidirectional hydraulic lock
  Outrigger bidirectional hydraulic lock is used to insure the  horizontal and vertical cylinder will not
  automatically retract when outriggers are in the extending state .
7) Rear axle steering lock and rear wheel return detector
  During the driving process,only front axle steering is needed and the rear should be returned aligned.For this
  reason a lock device is used and indicating light on the instrumentation board shows the status.
8) Emergency steering power device (emergency pump)
  If there is  an emergency that the engine can not be started,  the crane can be dragged by other vehicles. The   
  emergency pump is driven by battery and supplies power to power cylinder .
