As we all know, it is significant for users to strictly abide by the regulations when using concrete pump trucks. The concrete pump truck is a kind of large-scale mechanical equipment. If it is not operated according to the regulations, it may cause accidents and endanger the lives of workers and on-site personnel. Check reasons for standard operation.
Few Reasons Why Compliance With Standards When Operation
- 1. It can ensure engineering quality and safety.
- 2. Helpful for extending the life span of the equipment.
- 3. It can improve working efficiency.
- 4. Reducing legal and financial risks.
By strictly adhering to the operational standards, we can guarantee the normal operation of the concrete pump truck and the smooth progress of the construction project. More importantly, we need to know what should be paid attention to during operation. Here are some main truck mounted pump operation points for reference.
Some Standards When Operating The Boom Pump
- The operator of the truck mounted pump should concentrate on the pumping process and always pay attention to the value of the pumping pressure gauge.
- Once the value of the pressure gauge suddenly increases, it should immediately reverse the pump for 2-3 strokes, and then turn the pump on and plug the pipe.
- If the reverse pump (forward pump) has been carried out for several operating cycles and the blocked pipe is still not eliminated, the pipe should be dismantled and cleaned in time, otherwise, the blocked pipe will be worse.
Appropriate Pumping Speed
- When pumping, the choice of speed is very important. When pumping for the first time, the pipeline resistance is relatively large. At this time, it should be pumped at a low speed.
- After the pumping is normal, the pumping speed can be increased appropriately. When there is a sign of pipe blockage or the slump of concrete is small, it should be pumped at a low speed to reduce the pipe blockage in the bud.
Properly Control The Amount of Remaining Material
- When pumping, the operator must observe the remaining material in the hopper at any time. The remaining material should not be lower than the stirring shaft.
- If it is too small, it is easy to suck air and cause pipe blockage. The material in the hopper should not be piled up too much and should be lower than the guardrail, to clean up the coarse aggregate and oversized aggregate in time.
- When the slump is small, the remaining material can be lower than the mixing shaft, and controlled above the “S” pipe or the suction port, to reduce the stirring resistance, agitation resistance, and suction resistance. Worth mentioning, the approach is only applicable to “S” valve boom concrete pumps.
Be Mindful of Downtime
During the downtime, the pump should be turned on every 5-10 minutes (the specific time depends on the temperature of the day, the slump of concrete, and the initial setting time of concrete) to prevent pipe blockage. It is not advisable to continue pumping the concrete that has been set for too long after the downtime.
Clean the Pipeline in Time
After the last pumping, the pipeline is not cleaned, which will cause the pipe to be blocked during the next pumping. Therefore, after each pumping, the delivery pipeline must be cleaned according to the operating procedures.
Correct guidance and compliance with the above standards will ensure the safety and smooth progress of the construction. In addition, the operators should strengthen the promotion of training and operating procedures to ensure the effective use of concrete pump trucks and minimize potential risks and losses.
