Concrete pump truck is a mechanical device that uses pressure to continuously transport concrete along the end concrete hose. Composed of pump body and delivery pipe. It can be divided into piston type, extrusion type, and water pressure diaphragm type according to its structural form. The pump body is installed on the chassis of the car, and then equipped with retractable or folding fabric rods to form a pump truck.

1) The structural components of the pump truck, such as the boom, support legs, and chassis, may undergo welding seam inspection after a period of time due to local stress concentration, oxidation and corrosion, and the variable load bearing during operation.

2) Cracks in the structure of concrete pump trucks are repairable. Users should promptly detect and handle issues as soon as possible. The load-bearing components such as the arm frame and support legs are made of high-strength steel and cannot be welded, drilled, altered or reduced in strength at will. If cracks occur, please contact the manufacturer in a timely manner for repair.

Welding tips:

Only qualified personnel commissioned by the manufacturer can carry out welding work on important components such as fabric poles, support legs, missing weights, or other components that affect safety operations. This work is inspected by authorized prosecutors.

The cables of the welding machine casing should be directly connected to the parts to be welded. Welding current should not flow through chains, hydraulic cylinders, etc. Closing the spark gap can cause serious damage.

During the welding process, external voltage may damage the email. To this end:

——Disconnect the remote control cable from the control box

——Disconnect all wires connected to the wireless remote control receiver;

——Cover the socket with a protective cover;

——Disconnect the positive and negative leads on the battery.
