The position of trailer concrete mixer pump should be in consideration of the site and way of adding material of concrete mixer pump when the concrete is mixed in the site. Then the position of concrete pump should be settled by the height of unloading material and requirement of suitable pump transportation and pipe connection. The procedures are listed in the following four steps:
1. Installment of pump
Put the concrete pump on the ground or stone pier and maintain level. And lock the four legs of the positioning pin and safety pin of the pump to make the tire off the ground or remove the tire.
Make a chute according to the outlet port and hopper of the concrete mixer pump to put material discharged by the pump into the hopper through the chute.
The chute uses angle iron as skeleton and is ironed by steel plate of 1.5mm in depth. Plank is used under the brace for security.
In usual, the hopper should be heightened about 20cm so the concrete will not be dropped with larger hopper. It is because that unloading material of forcing concrete mixer pump should be done one time to make sure the smooth concrete flowing into the pump. If unloaded for several times, more stones will be in the concrete and do harm to the pump. Particularly, the hopper should be higher when the slump is larger. If it is a large-quantity mixer pump, a material-reserved hopper should be made for incessant material supply.
