The core function of a cement pump truck, also known as a concrete pump truck, is to continuously transport concrete to the construction area along a specific pipeline under pressure. Although many people are involved in the field of work related to pump trucks, many pump truck operators do not know how to operate this equipment safely and efficiently. To this end, we will provide a comprehensive operation guide for all pump truck operators on this issue.
The stability of the pump truck outriggers is crucial
It is related to the safe operation of the entire pump truck. Just like the horse stance in kung fu, the stability of the lower body is the key to avoid being pushed over. Therefore, the pump truck operator must ensure that the outriggers can be firmly “stuck” on the ground to ensure the safe operation of the pump truck.
When operating a pump truck, be sure to pay attention to the dangerous area within the rotation range of the outriggers. When unfolding or retracting the outriggers, there is a risk of pinching in this area, so be extra careful to ensure the safety of yourself and the people around you.
Keep communicating with construction personnel to prevent ground collapse
The pump truck must be firmly supported on solid ground. If the maximum pressure of the outrigger exceeds the allowable pressure of the ground, support plates or auxiliary square timbers should be used to increase the support area. Before arranging the outrigger, be sure to communicate with personnel familiar with the situation on the construction site to ensure that there is no sewer under the outrigger. When supporting near potholes or ramps, a sufficient safety distance should be maintained to prevent ground collapse.
Strictly control the deflection angle of the pump truck, not exceeding 3 degrees
After the support is completed, the horizontal deflection angle of the front, back, left and right of the pump truck should be carefully checked to ensure that its maximum deflection angle does not exceed 3 degrees. Usually, during the construction process, the direction in which the boom is extended will be slightly raised to reserve space for sinking after the boom is extended. Modern pump trucks are generally equipped with electronic levels and alarm devices. Once the inclination angle of the pump truck is too large, the alarm will sound an alarm to remind the operator. Before extending the boom, be sure to confirm that the outrigger is firmly supported.
Two-person collaborative operation to ensure safety and efficiency
The operation of the pump truck requires the collaboration of at least two people. One of them is responsible for operating the remote control to control the operation and pumping function of the boom; while the other needs to pay attention to the status of the boom and legs of the pump truck at all times, and monitor the quality of the aggregate entering the hopper. Through effective communication and collaboration, the safety and efficiency of the pump truck operation can be ensured.
A dedicated person is required to direct the tank truck when reversing to prevent collision accidents
During the operation of the pump truck, the reversing link of the tank truck is crucial. To ensure safety, a dedicated person must be designated to direct the tank truck to prevent its tail from colliding with the pump truck.
During the pumping operation, make sure that no one stays under the boom. This is not only to prevent the danger caused by accidental breakage of the boom, but also to avoid sudden shaking of the boom caused by changes in pressure and weight in the pipe, thereby ensuring construction safety.
Problems and countermeasures of pipe blockage in pump trucks
During the operation of pump trucks, pipe blockage is a common and troublesome problem. It may be caused by a variety of factors such as pumping technology, aggregates and ease. When pipe blockage occurs in the early stage and cannot be solved by reverse pumping, we recommend the method of disassembly and elimination. Forced pumping may cause the pump tube to burst, posing a safety hazard.
