Safety precautions for concrete pump truck support
Safety precautions for concrete pump truck support
1. The supporting ground must be level. Otherwise it is necessary to make a horizontal support surface. Cannot be supported on the cavity.
2. The pump truck must be supported on a solid ground. If the maximum pressure of the outrigger is greater than the allowable pressure on the ground, a support plate or auxiliary square wood must be used to increase the support surface area. 3. When the pump truck is supported near pits and slopes, sufficient safety distance should be reserved.
4. When supporting, it is necessary to ensure that the whole machine is in a horizontal state, and the maximum horizontal declination angle of the whole machine is not more than 3 degrees.
5. When unfolding or retracting the outriggers, the range of the outrigger rotation is a dangerous area, and personnel may be pinched within the range.
6. When supporting, all outriggers must be telescopic and unfolded to the specified position (the outriggers are aligned with the arrows on the lugs, and the front outrigger arms are aligned with the arrows on the front outrigger arms), otherwise there is a danger of tipping.
Application Note Safety Precautions:
1. The concrete delivery pump truck can only be used for the delivery of concrete. Do not use it for other purposes, such as lifting, it is very dangerous.
2. The height and distance of the concrete pumped by the boom of the pump truck are strictly calculated and verified. Any subsequent connection of the pipe at the end of the hose or the extension of the end of the hose to more than 3m is not allowed, resulting in The risk is borne by the operator himself.
3. It is forbidden to modify the pump truck without authorization and permission, including changing the safety pressure and running speed settings; changing to a large-diameter conveying pipe or increasing the wall thickness of the conveying pipe, and changing the control program or circuit. Changes to booms and outriggers, etc. 4 Pump truck operators must wear safety helmets and abide by safety regulations and safety regulations on the construction site.
