Safe operation process of wet spray manipulator
For the safety of the construction personnel, the safety operation process of the wet spray manipulator is specially made: 1. It is strictly forbidden to use the manipulator as a crane or lifting platform. 2. Do not move the vehicle and operate the manipulator at the same time. After the vehicle reaches the working position, it must be fixed to prevent rolling: use the handbrake, turn off the engine, and place the driving direction joystick in the neutral position.
3. Make sure that no one is in the danger zone when extending the outriggers. The control device must be easy to operate to ensure safety. 4. Only those who have received professional technical training and passed the assessment can operate, use, maintain and maintain this equipment. 5. Due to the heavy weight of the sprayer, it is required to place the ground tightly, so that the sprayer can be positioned reliably and in a horizontal state, and ensure that the outriggers of the vehicle are sufficient before starting the manipulator or concrete pump, or before pouring the sprayed materials into the hopper Extend to prevent tipping. 6. The concrete sprayer should have a power cord of at least 50 meters in length, the voltage and frequency used are in compliance with the regulations, and the phase sequence is determined.
7. When the running distance is far, the manipulator should turn to the transport position, and the boom should be supported by a support. 8. When using the remote control, the unintentional movement of the handle will cause the manipulator to move, so special attention should be paid. 9. When moving the vehicle, the boom and sliding arm should be fully retracted in the parking position. 10. 9 inspections before operation: check the hoses and connections for damage and aging. The vacuum gauge of the suction filter element and the gauge of the oil return filter must be checked every time it is started. If the pressure gauge indicates in the red area, it indicates that the filter element should be cleaned or replaced.
Set the pumping volume controller to the "0" position. Check the admixture hose connection. Check that the pipe joints are well sealed and that they are not loosely tightened. The electrical circuits and motors are well insulated, free from damage or leakage. The electrical box meets the requirements of the specification, and the grounding and zero connection are intact and not loose. The batching system should be vented first to prevent damage to the additive pump. Prepare enough admixtures. Check whether the high-pressure joints of the delivery pipeline (nozzle system) are in place and free of faults. Check if the water tank is filled with water. Check the oil level in the hydraulic oil tank.
