Nowadays, with the economic development, coupled with the acceleration of high-speed railway construction and the continuous expansion of the housing industry, the market demand for concrete pumps has been continuously stimulated. The mechanical valve systems and hydraulic systems of concrete pumps have also continued to innovate, and concrete pumps have gradually become larger. In the direction of power and high reliability, many key technologies have also been better solved, which makes construction workers more handy when using concrete pump trucks . What are the skills when operating with concrete pumps ?

1. The size of the sand and gravel, the grade of cement, and the mixing ratio should meet the requirements of the mechanical properties of the pump according to the requirements of the factory instructions.
2. The outriggers should be fully extended and firmly supported. Do not start the cloth boom before fixing. The cloth rod can be turned after raising the bracket. The spreading rods should be carried out in sequence. Do not use cloth poles to lift or drag objects.
3 The bolts of each part of the pumping equipment should be tightened, the pipe joints should be tightly sealed, and the protective devices should be complete and reliable.
4 Prepare relevant devices such as cleaning tubes and cleaning supplies. Before operation, the pipeline must be lubricated with cement mortar prepared according to regulations, and unrelated personnel must leave the pipeline.
5 The parking brake and locking brake of the pumping equipment should be used at the same time, the tires should be wedged, the water supply should be normal, and the water tank should be filled with fresh water, the hopper should be free of debris, and the lubrication points should be lubricated normally.
6 Manipulate the opening of each part, adjust the handle, handwheel, control lever, cock, etc. in the correct position. The hydraulic system should be leak-free.
7. Scientific and reasonable selection of additives to improve the mechanical properties and durability of concrete.
8 The ground supporting the concrete pump should be flat and solid; the whole machine needs to be placed horizontally, and it should not be inclined during work. The outriggers should be able to support the whole machine stably and be locked or fixed reliably. The position of the pump should be convenient for the concrete mixer truck to enter and exit the concrete hopper and feed the hopper, and it should also be considered to be beneficial for pumping the distribution pipe and reducing the pumping pressure loss. At the same time, it needs to be close to the pouring site, and convenient for power supply and water supply.
9 After the concrete pump communicates with the conveying pipe, a comprehensive inspection should be carried out in accordance with the instructions of the concrete pump instruction manual, and it can be started for dry running after meeting the requirements. After 10 minutes of no-load operation, check whether each mechanism or system works normally.
10 The first batching (feeder) metering process of the concrete batching machine is an automatic drop correction program. In the future, the ingredients will be batched according to the result of this correction, and each material will be batched into two sections during the automatic correction to meet the measurement requirements.
11 The parking brake and locking brake of the pumping equipment should be used at the same time, the tires should be wedged, the water supply should be normal and the water tank should be filled with fresh water, the hopper should be free of debris, and the lubrication points should be lubricated normally.
