SQ8SK3Q Telescoping Boom Crane
1.Throttle Control System
Changing the form of previous manipulation and throttle operationindividually,Realization of the bilateral handle synchronous and driving throttleacceleration and deceleration automatically, due to the speed change steady,it can easily to carry out the lifting work.
2.End position automatic hookdevice
Maximum savings in preparation time before and after operation, to ensurethat customer’s vehicle could be in a driving state in the shortest time, andprevent crane damage accident caused by hoist swing to enhance the safety ofdriving.
3.Hoisting overwinder device
If a user is negligent or unfamiliar with the operation of lifting hooks,the hoistingoverwinder device will stop hook raise in time, to prevent the safety ofpersonal and property caused by fracture of wire rope.
4.Slewing locking device
Slewing locking device can ensure that the lifting arm does not swaybecause of the centrifugal force during the driving and steering process of thevehicle,to avoid all kinds of accidents caused by swaying.
5.Dual pump converging
The hydraulic system adopts dual high pressure gear pump, multi-way valvehoisting joint to realize the converging, to improve the speed of winch, at thesame time, it can realize the compound action of crane.
6.Torque limiter
It can select torque limitoverload protection device to prevent users because of negligence or unfamiliar with the liftingoperation principle of overload operation, thereby causing the vehicle rolloverand crane damage accidents.
