Immediately retract the boom and re-support the pump before operating;

3.4 When a concrete pump truck enters the construction site, it must observe the condition of wires and cables within the working range, understand the line voltage, and ensure whether the minimum safe distance is reached according to different voltages. (Note: 0-lkv shall not be less than lm; l-10kv shall not be less than 3m, l10-220/kv shall not be less than 4m, 220-400kv shall not be less than 5m, and when the voltage is unknown, it shall not be less than 5m.) If the minimum safe distance cannot be reached, the construction site must be required Work can only be done after a power outage. -

3.5 When transferring concrete towable pumps, the maximum speed of the concrete mixer truck driver towing the pump at the construction site shall not exceed 8km/h;
