Precautions for application safety
1 concrete pump truck can only be used to transport concrete, and any other use (such as lifting heavy objects) is dangerous.
The height and distance of concrete pumped by the boom of pump truck are strictly calculated and confirmed by experiments. It is not allowed to connect the pipeline behind the end hose or lengthen the end hose by more than 3m, and the risks arising therefrom shall be borne by the operator.
3 It is forbidden to modify the pump truck without authorization, which may affect the safety, including changing the setting of safety pressure and running speed; Use large diameter conveying pipe or increase the wall thickness of conveying pipe, and change the control program or circuit. Changes in suspenders and legs, etc.
4 Pump truck operators must wear safety helmets and abide by on-site safety regulations and safety regulations.
Safety precautions of support
The supporting ground of 1 must be horizontal. Otherwise, it is necessary to make a horizontal bearing surface. Can't support on the cavity.
The pump truck must be supported on a solid ground. If the maximum pressure of the leg is greater than the allowable pressure on the ground, it is necessary to use supporting plates or auxiliary square timber to increase the supporting surface area.
3 when the pump truck is supported near the pit and slope, sufficient safe spacing should be left.
4 when supporting, ensure that the whole machine is in a horizontal state, and the maximum horizontal deviation angle of the whole machine is not more than 3 degrees.
5 When the legs are unfolded or folded, the rotation range of the legs is a dangerous area, and people may be caught in this range.
6 When supporting, all the legs must be extended to the specified position (the legs are aligned with the arrows on the lugs, and the front leg arms are aligned with the arrows on the front leg extension arms), otherwise there is a danger of overturning.
You must support your legs as required to operate the boom, and you must put the boom on the main support of the boom to make ends meet.
8 factors that reduce stability must be folded immediately, and then re-supported as required after elimination. Factors that reduce stability include
Changes in ground conditions caused by rain, snow water or other water sources; Safety measures of outrigger when one side of outrigger cylinder touches the ground.
1 Only after confirming that the legs of the pump truck have been correctly supported can the boom be operated, and the operation of the boom must be carried out in the order specified in the operation procedure.
In the case of thunderstorm or bad weather, the derrick can't be used. Derrick can't be used in weather with wind force greater than 8.
3 When operating the boom, all the booms should be within the operator's field of vision.
4 Be careful of the danger of electric shock when working near high-voltage lines, and ensure the safe distance between the boom and the wires.
Below the boom is a dangerous area, and concrete or other parts may fall and hurt people.
No one is allowed to stand within the specified range of the end hose, and the end hose shall not be guided when the pump truck starts pumping, which may swing and hurt people or cause accidents by spraying concrete.
The dangerous area when starting the pump is the surrounding area where the end hose swings. The diameter of this area is twice the length of the end hose. The maximum length of the end hose is 3m, and the diameter of the dangerous area is 6m.
7 Don't bend the end hose. The end hose can't extend into the concrete.
8 If the boom moves abnormally, press the emergency stop button immediately. Professionals should find out the reason and eliminate it before continuing to use it.
