Chapter 2: Brief introduction of QRY20
RT20 rough terrain crane is a kind of telescopic boom and swing variety crane which travels with tire variety 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, etc. The undercarriage is composed of the suspension and wal ept part. The superstructure and the undercarriage are related by the slewing bearing.
Chapter 3: Primary functions of QRY20
one. Entrance-wheel steering, rear wheel steering, 4 wheel steering and crab steering, all wheel push, off-highway
performance, appropriate for off-freeway travel.
two. The axle adopts Meritor axle
three. The gearbox adopts the ept manufacturer.
4. Provider brake adopts Double circuits air bra ept system Par ept brake adopts air bleed bellow bra ept system.
5. Entirely extended outriggers procedure, with semi-stretch outriggers procedure, with no outriggers operation and touring with load operation can be realized.
6. Suited for slim space journey and operations small turning radius robust maneuverability.
7. Protected and reputable control method, two seats or a single seat can be optional, all-directional lifting procedure,
  greatly enhanced the ability of the front lifting.
8. The crane has very good traffic-potential, dynamic overall performance and mobility, and is in a position to operate in every course and vacation while hoisting without having outriggers. The product is widely utilized in heavy lifting functions, limited distance transfer, narrow-site lifting operations for construction web sites, outdoor oilfields, warehouses, freight yards, logistics basses and other sites.
Chapter 4: Protection unit of QRY20
 Safety system contains torque limiter, swing table lock gadget, winch in excess of-winding and more than-leisure defend gadget, outrigger lock unit, outrigger bidirectional hydraulic lock, rear axle steering lock and rear wheel return detector, emergency steering electrical power unit, gradienter, hydraulic method overflow valve, harmony valve.
1) Torque limiter
 Detecting operate: Detect the angle of the growth immediately.
 Display function: Display running details such as actual load, dealing with radius, growth angle.
 Caution purpose: When the true load exceeds rated lifting load, torque limiter will give an alarm and stop the operation.
two) Swing table lock unit
  During the driving process, a plug device is utilized to link the swing table and the provider to hold the steering elements (swing table, increase) from swing induced by inertia.
three) Winch more than-winding shield device 
  When the load reaches a specified height,torque limiter will quit the slipping and indicating gentle on the instrument panel will be on.
4) Winch over-peace shield gadget
  When only 3 laps of rope is left on the winch, torque limiter will end the falling and indicating gentle on the
  instrumentation board will be on.
five) Outrigger lock system
  During the driving method, a plug gadget is used. By plugging the outrigger, the gadget deeps it from extending.
six) Outrigger bidirectional hydraulic lock
  Outrigger bidirectional hydraulic lock is utilised 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 procedure, only front axle steering is needed and the rear need to be returned aligned. For this explanation a lock unit is employed and indicating gentle on the instrumentation board exhibits the status.
eight) Emergency steering electrical power unit (unexpected emergency pump)
  If there is an unexpected emergency that the motor can not be started, the crane can be dragged by other cars. The crisis pump is driven by battery and materials energy to electricity cylinder.
