How to operate the concrete pump truck hose

The hose of the concrete pump truck should also pay attention to the operating skills. If you don't pay attention, it is easy to cause the hose to be blocked or even explode. The following three aspects should be paid attention to during the operation of the hose: 1. When starting or stopping to pump concrete, you should contact the operator of the front hose. The bending radius of the front hose should be greater than 1m, and the operator is not allowed to stand at the outlet of the pipe to prevent the concrete from suddenly spraying out and injuring people.

The delivery pipeline of the small concrete pump truck should be fixed and padded. It is strictly forbidden to bend the delivery hose to prevent the hose from exploding. When the pipeline is blocked, the end of the soft joint will swing rapidly when it is pumped after treatment, and the concrete may be sprayed instantly. The staff should not approach the hose.

1. Never stand at the corner of the building and hold the end hose in your hand. The shaking of the hose or the spraying of concrete may cause the operator to fall from the building.

2. Before the small concrete pump truck pumps concrete, first pump clean water, check each pipe clamp to ensure that the seal is not leaking and then pump the pipeline lubricant. Generally, mortar is used, and cement slurry can also be used. Pour the mortar into the hopper for pressure delivery. When the mortar is about to be pressure-delivered, pour the concrete that meets the requirements for normal pressure delivery. If the mortar is blocked, remove the front section of the pipe, take out the internal dehydration block, and connect the pipe, and it can operate normally.

3. When the small concrete pump truck is running, it is strictly forbidden to put your hands into the hopper or water tank. During the pumping process, the concrete material should be kept above the mixing axis, and it is not allowed to suck empty or pump without material. If the pumping is suspended for a long time, the pump must be turned on every (15-30) minutes, reverse pump 1-2 strokes, and then forward pump 1-2 strokes to prevent the concrete material in the pipe from condensing.

There are also many precautions for the hose of the small concrete pump truck. Remind everyone to frequently check whether the hose safety chain and the boom are firmly connected. When the pump truck is operating, pay attention to prevent the rubber hose from bending and clogging. Safety operation specifications, civilized construction, and safe construction.
