Pay attention to these points during the operation of the concrete pump truck. Only by doing so can the use of the pump truck be safe.

Do not put your hands into the hopper, mixing device, or water tank when the concrete pump truck is running. When the operation is temporarily stopped, be sure to turn off the engine and press the emergency stop button. Before the pump truck enters the construction site and unfolds its outriggers, the handbrake should be pulled down and the wheels should be fixed with wheel blocks. When pouring concrete, all the legs should be fully deployed before the boom can be operated. The boom should be deployed in the order specified in the operation and use of the pump truck.

The vehicle body must be kept horizontal, with the inclination of the front, rear, left and right sides less than 3 degrees relative to the horizontal plane. And only after folding the boom and placing it on the main support of the boom can the legs be retracted. Before moving the boom and unfolding the legs, check whether there are any obstacles around it. Prevent the boom or legs from touching buildings or other obstacles. When the operator cannot observe the entire working area or cannot accurately determine the distance between the extended part of the pump truck and adjacent objects, a guide should be provided to provide guidance.

Construction operation technology

When loading the tanker for the first time, two more bags of cement should be added. After loading the concrete, the conveyor should keep rotating at a slow speed. Before unloading, the conveyor should speed up and rotate for 20 to 30 seconds before unloading.

When pumping concrete to pour the mannequin, there are two pouring sequences: layered pouring and side pile pouring. The end hoses should be moved evenly to control the thickness of each layer of fabric to 20 to 30cm. It should not be poured in piles. When pouring with horizontal pipes, as the concrete pouring direction moves, 1 to 2 people should be considered in the pouring area of each pump truck to watch the distribution boom and direct the distribution, and 6 to 8 workers should dismantle and assemble the pipes, and gradually lengthen or shorten them. , to adapt to the movement of the pouring part.
