No matter what kind of concrete pump, the working principle is the same, but in some places there are subtle differences, according to a large number of cases of small accidents happened in the past analysis, concrete pump in operation, easy to cause the accident in the following five parts and links:

1. pump mixing funnel part
happens every year many accidents. For example, when the pump truck hopper when a fault occurs, the operator needs to remove the hopper of the concrete, if a mechanical operated, cleaning staff will be hurt; when the stirring device failure, maintenance personnel in the hopper to repair the stirring device, when another person began to test whether the repair, maintenance personnel will be hurt.

2.
rollover when the concrete pump is developed, and is the work of the concrete pump truck capacity by four legs to support the whole pump, if the construction site is not plain, leg pump uneven force, will rollover.
3. pump easily in the car overturned
had occurred due to pump malfunction of the overturning accident, when completed pouring task, workers eager to call it a day, in the absence of back cloth rod, start back legs, causing rollover accident.

4. electric shock
is similar to electric shock of crane. As the concrete pump truck works in the cloth, the cloth pole needs to be raised high, and the boom is easily close to the high-voltage wire near the construction site, resulting in an electric shock accident.
5. fabric operation
cloth operation, concrete pump truck operators and fabric placement construction workers coordination is not good, if the two sides violate the operation rules, easy to cause accidents,
