Three, the sky pump 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. In addition, you must communicate with familiar people on the construction site before setting up the legs to ensure that the legs are not on the sewer.
Four. Keep a safe distance to prevent ground subsidence
When supporting near pits or ramps, a sufficient safety distance should be reserved to prevent ground subsidence.
five. when the outriggers enter the water
If rainwater, outrigger cylinder leakage and factors that reduce the stability of outriggers occur, the boom should be folded immediately, and the outriggers should be supported again according to the requirements after exclusion. When supporting the pump truck, it is best to keep the tires about 5 cm away from the ground, otherwise the vehicle's driving mechanism will be damaged due to the swing of the pump truck's S swing pipe and the impact of the pressure inside the pipe.
