The crane hook handling precautions

1 reverse speed
Dongguan crane speed reversal is refers to the reverse driving device, sling up an additional component in the maximum operating speed of the reverse speed. High velocity inversion, although progress crane operation power, but in the inversion motion in a return of Wai Zhuan moment of inertia also, of crane safe operation unlucky. Therefore, in heavy work, the driver should according to the specific circumstances of the job site and a hanging component, correctly pick choose suitable reverse speed.
2 amplitude
The range velocity is the velocity of the head of the boom. The variable amplitude speed has little effect on the output power of the crane, but it has a great influence on the operation balance and safety of the crane. Therefore, the operator should take the low amplitude rate when the crane is used in the operation.
3 elastic velocity of boom
A crane with a hydraulic flexible boom structure can be used to lift up the height of the lifting height and the fluctuation of the job. But in the lifting operation, the flexibility of the crane, the stability and safety of the crane, the driver is necessary to strictly comply with the operating rules and the use of lower elastic speed.
Usually the arm extended speed roughly within 6~10m/min. Because of the size effect of cylinder two chamber is not the same, some extended speed faster than the retracted.
4 leg speed
With a hydraulic support legs of the crane, the hydraulic support legs, the speed of the time to show that its hydraulic support legs, stretching speed is usually between 15~50s.
