Pouring concrete placing boom safe operation

When pouring with concrete placing boom, we should follow some safety operation, in order to improve the efficiency.

1. Prepare the real-time conversation tools, easy to operate and better exchange reminder. Construction at

night, people must be accompanied by concrete control flashlight, see the concreting height.

2. If the discharge hose break at work or out of the further movement of the boom, it will hit the hose

operatives who cause harm. This risk also occurs when the hose suddenly clogged. And when pumping starts,

due to the sudden movement of air containing debris or boom, shake resorted hoses, the operator will cause

some damage.

3. Start the pump when the danger zone is the discharge hose can shake out of the surrounding area, the

area twice the diameter of the discharge hose length.

4. Do pumping operations open conveying pipe card, prohibited the hose is inserted into the concrete.

5. Discharge hose plus non concrete pump rubber hose, prohibit the use of longer than 3m hose pouring end. Do the ends of the

hose removed, so that the boom and the other rigid delivery pipe connections.

6. The hose should be locked safety chain, hose safety chain should be firmly fixed on the boom can not be

fixed on the steel tube and pipe the output card.

7. Concrete placing boom at work, not allowed to stand in the below.

8. Do open pipe joints in the duct and pressure tubing, hydraulic system pressure must not exceed 25MPa.

9. rotation during braking or do the reverse operation is prohibited when the machine does not stop,

turning the hoop at the joints can not be fixed tightly to ensure flexible rotation required per shift to

clean, lubricate swivel joints sealed tube hoop again.

10. When maintenance, disconnect ground power, repair and maintenance are not allowed to live.
