Do you know the safety rules for pump truck parking?

   one The parking area of the pump truck should be as wide as possible, enough to fully extend each leg, check whether there are obstacles around, prevent the boom or outrigger from touching the building or other obstacles, and the operator's sight should be able to reach all corners of the working area. When the operator can not observe the whole operation area or can not accurately determine the distance between the pump truck extension and adjacent objects, a guide shall be assigned to command. Never use the equipment against rules and allow the equipment to run alone.

two According to the requirements of safe operation, warning equipment shall be used to separate the workplace from traffic and the public.

three The pump truck must be parked on the solid ground to ensure the stability of the pump truck. Keep away from dams, ditches, etc. Because the ground in these places is under the pressure of the outrigger, it may cause collapse and affect the stability of the pump truck. When the pump truck is working, it should keep a safe distance from the trench, slope, excavation base surface, cable, etc.

Due to unstable supporting surface of the dam, the equipment is easy to drop !

The support shall follow the following basic principles:

(1) the distance between the bearing surface and the groove is greater than or equal to the depth of the groove two Times.

(2) the bearing surface shall be kept horizontal: if the bearing surface is located on the inclined plane or the uneven place, a plane shall be excavated on the inclined surface for supporting.

warning : If the vehicle parking position is not correct, the pump truck will be unstable or even overturned !

four When the pump truck stops on the slope, put the wedge behind the wheel. Release the brake and let the equipment roll slowly towards the wedge. When the wheel slides onto the wedge, pull on the hand brake, pad the wedge, and then extend the outrigger.

five The pump is usually parked horizontally. The pump truck is leveled by adjusting the outrigger.

six The pump must be parked on the ground to ensure the stability of the vehicle. The pressure of the outrigger acting on the ground can reach 26kg /cm2. If the ground is not solid enough, some skids must be placed at the foot of the support.

seven Pump truck must be away from pits, dams, ditches, etc. Because the ground in these places is under the pressure of the outrigger, it may cause collapse and affect the stability of the pump truck.

eight During the process of material distribution, the support legs should be checked and adjusted if necessary. Due to the different position of the outrigger on the ground, the stability of the outrigger can be ensured by adjusting the outrigger on the ground.

nine When the pump truck works, keep a safe distance from the crane, buildings and other obstacles. Special care must be taken in the place where there are electric wires, and pay attention to keep a safe distance from the electric wires, otherwise the pump truck and nearby or connecting objects ( Remote control device, hose end, etc ) The life of the personnel on the operation is in danger. When high-voltage spark appears, a high-voltage funnel area is formed under and around the equipment ( Step voltage ) The current generated by the voltage flows into the human body.

DANGER ! Watch out for high voltage lines ! Keep the edge of the work area away from the power line at least five Meters away.

be careful ! Wind speed requirements: when the boom is working, the wind speed shall not exceed six level ( Equivalent to wind speed 13.8m /s)

ten When working, put the pump truck in a horizontal state ( The maximum allowable slope is 3°)

be careful ! The larger inclination can overload the slewing device of the boom and affect the stability of the whole vehicle.

be careful ! When placing the outrigger, prevent the body from being sandwiched between the outrigger and other objects !

eleven No one is allowed to stand in the boom operation area !

twelve When supporting, all outriggers must be extended in place.

be careful ! Never allow the boom to be deployed until the four legs have been stopped.

thirteen Support the outrigger as required before operating the boom. On the contrary, the jib must be retracted in place after operation.
