How do the Small Concrete Pump Truck carry on?
It is necessary for a Small Concrete Pump Truck to carry out dozens of meters jib for transportation when transporting, but most of the time, many construction sites are not large, and there is no need to expand all the arms of tens of meters. In this case, how do we pump the small pump cars?
With the rest of the crane arm stretching ratio, the small pump truck boom because of the special structure of folding, in pump construction boom will only spread out, with the method of adjusting arm bending to realize pump. It is necessary to reduce the length of the brachial boom of the Small Concrete Pump Truck to allow the unfolded arm to adapt reasonably to the demand for short pump construction. The long distance pump is chosen to use all the arms, and the short distance pump is chosen to use a part of the arm. According to the pumping distance selection method of arm frame, can not only play a pump pumping capacity of existing car, but also for short distance pumping construction, according to the need to select the part of the arm, the height of arms is reduced effectively, reduce the length of the pipeline, but also can save money.
The characteristics of the short pump delivery technical scheme of the small pump car are that the mechanical movement process of the boom recovery is more coordinated with the working process of the pipe switching mechanism. In the long distance pumping, the pipe is switched on the arm frame before launching, and then all the arms are carried out. The end gear 16 of the pipe switching mechanism and the end chain gear 15 are only meshing or separating, and the transmission relationship remains unchanged. When a small pump is pumped in a short distance, the pipe is switched on the arm frame before launching, and then only a part of the end arm can be carried out for pumping construction.
