Guhe UNIC truck crane adopts the linkage accelerograph to speedup according to moving one operating rod, because the speed changes equably, the crane can be operated easily.
Linkage accelerograph couples the operating rod and truck accelerograph. When pull the operating rod lightly, the crane will work andante; if pull the operating rod more emphatically, the engine will run in high speed and drive the crane work in high speed.
l The general crane, the operating rod and accelerograph operating rod is separated. Before the operator can master the operating technology expertly, it is different to operating the working speed of crane when using two operating rods at the same time.
Working safety of hexagon lifting boom
The hexagon lifting boom can reduce the transversal shake and rock when working. Because of the characteristics of high-intension and small-deadweight, the working ability of crane is advanced greatly.
l Regarding to the hexagon section lifting boom, the contract of two section booms is upper point and lower point, it can restrain the transversal sliding.
l Regarding to the quadrangle section lifting boom, the conract of two section booms is upper side and lower side, it can’t restratin the transversal sliding.
The crane is equipped automatic drawing-in and sending-out system, it can be operated easily by the special operating rod and save the time of starting and ending working and labour.
l The general crane, the lifting hookblock must be fixed by the steel wire line. So, the operator must go to the loading table when starting and ending the crane working.
