[Asia Pump Network News] Concrete pump truck, also known as concrete pump truck, the use of pressure concrete along the pipeline for a continuous transmission of machinery. Has been widely used in housing construction, bridges and tunnels and other construction and construction, so its safe operation is also much attention. So how to safely operate concrete pump truck? Now we introduce as follows. How to safely operate concrete pump truck? 1, the site during the concrete pump operation, should be as far as possible away from the high-voltage lines and other obstacles, so as to avoid accidents in the operation. 2, pre-job inspection Before carrying out operations, concrete pump truck console power switch should be located "off" position, while the concrete displacement handle and mixing device should be reversed handle should be located in the middle. 3, the legs in operation, the concrete pump truck should be placed horizontally, the support of the ground should ensure that the flat and solid, does not appear the status of subsidence, the other leg should ensure stability can support the whole machine, and can be reliably locked. 4, boom operation Boom in the folded state from the retractable or retracted, must be carried out in accordance with the provisions of the order. The specific operation is that the boom operation must be carried out after the boom has completely left the boom support bracket. In the event of a storm or when the wind power reaches level 8 or above (wind speed 16-17 m / s), it can not Use the boom. In addition boom can not be used for lifting operations. 5. Pumping operation When starting or stopping the pumping of concrete, first contact the operator at the end of the hose; under normal circumstances, the end of the hose bending radius of not less than 1 meter, and are not allowed to bend In addition, before disassembling and plugging the pipeline, anti-pump should be anti-2--3 times, to be confirmed that there is no residual pressure in the pipeline before disassembly. 6, post-operation inspection jib should be fully retracted, legs should be fully retracted, while inserting the lock pin. In addition the console power switch should be in the "off" position. 7, accumulator gas Need to be alert is that only accumulate nitrogen into the accumulator can not be washed into oxygen, hydrogen and other flammable and explosive gases, in order to avoid accidents. 8, emergency shutdown button Concrete pump truck there are many emergency shutdown button, these emergency shutdown button were set in the leg control valve, wired and wireless remote control system and control box, in case of emergency, simply press one of them Emergency shutdown can then turn off the machine. It should be noted that, once the emergency shutdown button fails, there may be unexpected situations in the case of unexpected danger can not shut down the machine quickly. It is advisable to check the function of the emergency shutdown button before starting work. Under normal circumstances, when the emergency button is pressed down, the machine's electric system is cut off, the solenoid valve, etc. will be closed. If the hydraulic system generates a leak, it will cause some problems such as the sinking of the fabricating rod. At this time, you can not press the emergency shutdown button. It should be noted that the safe operation of concrete pump truck operation is very important for the operator. In order to ensure the safety of concrete pump operation, to avoid causing personal or equipment accidents, operators must strictly comply with the above safety operating procedures.
