What are the safe operation procedures for concrete pump trucks?

 In the construction process to ensure the smooth progress of the project, follow the safe operation of the process is very important. In order to reduce the maintenance cost and improve the service reliability and service life, the pump truck must reach the specified technical status. So the work of the concrete pump truck safe operation of the process has what? We talked to experts on the subject.

  Experts pointed out that: construction to ensure the safety of concrete pump truck operation, to avoid causing personal or equipment accidents, operators must strictly abide by some safety operating procedures, in order to reduce the frequency of fault problems in the construction. So what are the concrete pump truck safe operation of the process? This can be done in the following ways:

   1. Venue selection

  When the concrete pump truck is parked, it should be as far away as possible from obstacles such as high-voltage line, and at the same time ensure that the parking ground is flat and solid, so as to ensure that it does not sink in the course of work and can support the weight of the whole truck of the concrete pump truck, concrete pump truck should be placed horizontally, legs can be stable and reliable to support the whole machine, and can be reliably locked. In addition, the state of the concrete pump truck should be checked, the power switch should be in the“Off” position at the operating table, and the concrete displacement handle and the mixer reversing handle should be in the middle position.

  2. Boom operation

  When the jib is extended or retracted in the folding state, it must be carried out in the prescribed order, and the slewing operation of the jib must be carried out after the jib completely leaves the jib bracket. If the pump truck is in a storm state or when the wind force reaches level 8 or above (wind speed 16 ~ 17 meters/second) , can not use the boom, boom can not be used for lifting operations.

  3. Check after pumping

  When stop pumping, should contact with the operator at the end of the hose, pay attention to the end of the hose bending radius should not be less than 1 meter, and not allowed to bend; Disassemble after confirming that there is no remaining pressure in the pipe. At the same time, attention should be paid to the jib fully retracted in the jib bracket, outrigger also fully retracted, and inserted into the lock pin, the power switch of the console should be in the“Off” position.

  4. Safety and security
  When the concrete pump truck is in use, the accumulator can only be flushed into nitrogen, not into oxygen, hydrogen and other flammable and explosive dangerous gases. In addition, the concrete pump truck has a series of emergency shut-off buttons, respectively, on the outrigger control valve, wired and wireless remote control system and control box. In the event of an emergency, just press one of the emergency shutoff buttons to shut down the machine. In case of emergency shutdown button failure, the machine will not be able to be shut down quickly in case of emergency, so it is necessary to check the function of emergency shutdown button before each work. When the emergency close button is pressed, the machine's electric system is cut off, resulting in solenoid valve, etc. . If the hydraulic system leakage, it will cause such as cloth rod sinking failure, at this time can not be used to press the emergency close button to solve the problem.
