Chapter 2: Quick introduction of QRY20
RT20 rough terrain crane is a type of telescopic growth and swing type crane which travels with tire sort chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting part, composed of the telescopic increase, jib, main winch, aux. winch, luffing system, counterweight, swivel table, etc. The undercarriage is composed of the suspension and wal ept component. The superstructure and the undercarriage are linked by the slewing bearing.
Chapter 3: Main features of QRY20
one. Front-wheel steering, rear wheel steering, four wheel steering and crab steering, all wheel push, off-highway
efficiency, appropriate for off-highway vacation.
2. The axle adopts Meritor axle
3. The gearbox adopts the ept brand name.
4. Service brake adopts Double circuits air bra ept system Par ept brake adopts air bleed bellow bra ept method.
5. Entirely prolonged outriggers operation, with semi-extend outriggers operation, without outriggers operation and traveling with load procedure can be realized.
6. Suitable for narrow room vacation and functions modest turning radius robust maneuverability.
seven. Risk-free and reliable manage method, two seats or one seat can be optional, all-directional lifting operation,
  greatly increased the potential of the entrance lifting.
eight. The crane has great targeted traffic-capacity, dynamic efficiency and mobility, and is able to function in every single route and vacation whilst hoisting with no outriggers. The item is commonly utilized in heavy lifting functions, short distance transfer, slim-web site lifting operations for building websites, outside oilfields, warehouses, freight yards, logistics basses and other websites.
Chapter 4: Basic safety system of QRY20
 Safety system contains torque limiter, swing desk lock gadget, winch over-winding and in excess of-rest defend unit, outrigger lock unit, outrigger bidirectional hydraulic lock, rear axle steering lock and rear wheel return detector, crisis steering electricity device, gradienter, hydraulic technique overflow valve, harmony valve.
1) Torque limiter
 Detecting perform: Detect the angle of the increase instantly.
 Display function: Display operating details such as real load, managing radius, growth angle.
 Caution function: When the genuine load exceeds rated lifting load, torque limiter will give an alarm and quit the procedure.
two) Swing table lock system
  During the driving method, a plug device is used to hook up the swing table and the provider to maintain the steering parts (swing desk, increase) from swing induced by inertia.
3) Winch more than-winding defend device 
  When the load reaches a particular height,torque limiter will stop the slipping and indicating mild on the instrument panel will be on.
4) Winch above-relaxation safeguard gadget
  When only 3 laps of rope is remaining on the winch, torque limiter will end the falling and indicating mild on the
  instrumentation board will be on.
five) Outrigger lock device
  During the driving method, a plug gadget is employed. By plugging the outrigger, the system deeps it from extending.
six) 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 condition .
7) Rear axle steering lock and rear wheel return detector
  During the driving process, only entrance axle steering is needed and the rear must be returned aligned. F820 Sequence The 820 Series has been designed employing the modular theory to accommodate higher-torque, higher- and lower-pace applications with the adaptability to accommodate a broad variety of torque configurations.or this cause a lock device is used and indicating light-weight on the instrumentation board displays the status.
eight) Emergency steering power system (unexpected emergency pump)
  If there is an emergency that the motor can not be started out, the crane can be dragged by other cars. The crisis pump is pushed by battery and supplies power to electricity cylinder.
