As more and more people choose to use the mixing pump truck in engineering construction. Mixing pump truck is a kind of construction equipment which integrates concrete mixing, pumping and laying functions, with the characteristics of compact structure and high efficiency and flexibility, widely used in the construction of rural civil housing, township and new rural construction, bridge, water conservancy and hydropower projects. Because the mixer pump has its own boom, there is no need for additional piping, which saves a lot of preliminary preparation.

Because of the outstanding performance of the mixer pump truck, its price is also relatively expensive, if the failure of the maintenance costs are not low, so in order to ensure the normal operation of the mixer pump truck, improve the service life of the mixer pump truck, the operator needs to regulate the use of the mixer pump truck, always pay attention to whether the mixer pump truck failure.

Boom pump truck in construction, pay attention to the following several issues:

1.The mixing pump truck enters the site, the operator immediately gets off, directs the vehicle to safely enter the construction site, pays attention to the roadbed situation to see if it can enter the car, there are no nails and protruding steel miscellaneous services to prevent trapping and flat tires

2. After the mixing pump truck enters the site, the operator determines the pump truck to be placed in a safe position according to the specific construction situation. Ask about the site, see if there are sewers, septic tanks, slopes, filling or not, and whether there are high-voltage power lines overhead to ensure the safe and effective leg of the pump (the sleepers must be well padded).

3. The mixing pump truck to expand the boom, put down the hose test boom action to see if there are no obstacles, playing empty pump for a few minutes and manual lubrication only to the size of the bearing seat out of the oil.

4. When pumping the mixer pump truck, hit the mortar first and then hit the concrete material, such as site ready-mixed mortar into the hopper after adding water to back-pump a dozen times, so that the mortar is fully and evenly pumped again. At this point the boom hose swing to no one, and then move to the designated position pumping after the concrete is played through. Remember it is very important!

5. At the beginning of pumping, check whether the legs are firm and reliable.

6. The mixing pump truck pumping midway due to material reasons or other factors blocking the pipe, immediately reverse pump twice and then positive pump, such as can not open, immediately stop, to the electronic control cabinet text display near control operation, the engine manual speed up and then select the fifth swing cylinder pointing, repeatedly pointing several times, and then reverse pump several times, and then positive pump if still can not be solved, then determine where the blockage in the removal of the pipe to solve, remove the pipe before the first must reverse pump pressure relief.

7. When the mixer pump truck pumping such as waiting for material time is too long, every 15 minutes to reverse pump / positive pumping several times, such as too long, turn the boom hose to the hopper positive pumping to hit the cycle.

8. When pumping the mixer pump truck, it is strictly forbidden to take over (the boom is easily damaged), keep the boom parabolic or horizontal as far as possible, and strictly forbid to reverse the last section of the boom to pump (the cylinder is easily bent).
