Safety requirements for using concrete pump:

(1) The particle size of the gravel, the cement label and the mix ratio shall meet the requirements of the mechanical performance of the pump according to the requirements of the manufacturer's instructions.

(2) The parking brake and locking brake of the pumping equipment should be used at the same time. The tire should be wedged tightly, the water supply should be normal and the water tank should be filled with clean water. There should be no debris in the hopper, and each lubrication point should be lubricated properly.

(3) The bolts of the various parts of the pumping equipment shall be fastened, the pipe joints shall be tightly sealed, and the protective devices shall be complete and reliable.

(4) Operate the beginning of each part, and adjust the handle, handwheel, control rod, cock, etc. should be in the correct position. The hydraulic system should be normally leak-free.

(5) Ready to clean the tube, cleaning supplies and other related devices. Before working, you must first lubricate the pipes with the cement mortar formulated according to the regulations. Unrelated personnel must leave the pipeline.

(6) The legs should be fully extended and fastened, and the feed bar must not be started before being fixed. The boom can be turned after the boom is raised. The boom should extend in sequence. It is forbidden to use the spreader to lift or drag the object.

(7) Never move the body when the boom is fully extended. When it is necessary to move during operation, the upper boom should be folded and fixed. The speed of travel should not exceed 10km/h. Distributing rods shall not use piping that exceeds the specified diameter, and the attached hoses shall be anti-seize safety ropes.

(8) Various instruments and indicator lights should be monitored at any time, and when they are found to be abnormal, they should be adjusted or processed in time. In the event of a blockage in the delivery pipe, the converse should be carried out to return the concrete to the hopper and, if necessary, to remove the blockage.

(9) When the pumping system is under pressure, no piping and hydraulic piping may be opened. The safety valve of the hydraulic system must not be arbitrarily adjusted. The accumulator can only be filled with ammonia.

(10) After the operation, all the concrete in the hopper and the pipeline must be output, and then the pump, hopper, and pipeline must be cleaned. When flushing the pipeline with compressed air, no person shall be allowed within 10m in front of the outlet end of the pipeline, and metal foam baskets and gravel pellets shall be collected using a metal net basket.

(11) It is forbidden to flush the distributor pipe with compressed air. The folding and shrinking of the distribution bar must be performed in sequence.

(12) All parts of the operation switch, adjustment handle, hand wheel, control sweat, cock, etc. should be reset. Hydraulic system unloading.

The construction of pumped concrete is a complex task. It is necessary to continuously summarize experience, improve processes, and improve the level of construction in order to reduce construction costs.
