QRY sequence of rough terrain crane is a type of telescopic increase and swing variety crane which travels with tire kind chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting portion, composed of the telescopic growth, jib, main winch, aux. winch, luffing system, counterweight, swivel desk, etc. The undercarriage is composed of the suspension and wal ept portion. The superstructure and the undercarriage are linked by the slewing bearing.
Primary attributes:
one) Entrance-wheel steering, rear-wheel steering, four-wheel steering and cab steering, all-wheel generate, off-street performance, suitable for off-freeway vacation.
2) All operations can be prolonged outriggers, semi-stretch outriggers work, all reduced outriggers function, outriggers work and do not flight visitors load.
three) Suited for narrow room vacation and operations modest turning radius robust maneuverability.
4) Protected and trustworthy management system, two-seats, all-directional lifting procedure, greatly enhanced the capacity of the front lifting operation.
5) The crane has good visitors-capacity, dynamic efficiency and mobility, and is ready to function in every single route and journey although hoisting without outriggers. The item is broadly used in hefty lifting functions, quick-length transfer, slender-site lifting functions for construction web sites, out of doors oilfields, warehouses, freight yards, logistics basses and other web sites.
Safety device:
Basic safety unit involves torque limiter, swing desk lock device, winch over-winding and more than-rest safeguard unit, outrigger lock system, outrigger bidirectional hydraulic lock, Rear axle steering lock and rear wheel return detector, crisis steering electricity system, gradienter, hydraulic method overflow valve, stability valve.
one) Torque limiter
Detecting function: Detect the angle of the boom routinely.
Display perform: Display operating details these kinds of as actual load, handling radius, increase angle.
Caution perform: When the true load exceeds rated lifting load, Torque limiter will give an alarm and end the operation.
2) Swing table lock system
During the driving process, a plug unit is employed to link the swing table and the carrier to maintain the steering components (swing table, increase) from swing triggered by inertia.
3) Winch above-winding protect unit
When the load reaches a particular top, torque limiter will quit the slipping and indicating mild on the instrumentation board will be on.
4) Winch more than-rest shield system
When only 3 laps of rope is still left on the winch, torque limiter will end the falling and indicating gentle on the instrumentation board will be on.
5) Outrigger lock system
During the driving prStandard Torq-Tenders are bidirectional. Torque benefit remains the same no matter of rotation. If specified, the torque limiter can be configured at the factory to release at different torque ratings for diverse rotational directions. When employed as a coupling, the Torq-Tender fulfills two functions: 1) A flexible shaft coupling 2) a mechanical torque limiter.ocess, a plug unit is utilized. By plugging the outrigger, the device deeps it from extending.
six) Outrigger bidirectional hydraulic lock
Outrigger bidirectional hydraulic lock is used to preserve both horizontal and vertical cylinder kind retraction.
7) Rear axle steering lock and rear wheel return detector
During the driving approach, only front axle steering is essential and the rear ought to be returned aligned. For this purpose a lock device is utilised and indicating light on the instrumentation board displays the position.
8) Unexpected emergency steering power gadget (unexpected emergency pump)
If there is an unexpected emergency that the motor are not able to be began, the crane can be dragged by other vehicles. The unexpected emergency pump is pushed by battery and provides electrical power to electricity cylinder.
