In our daily lives, pneumatic winches require professional personnel to operate. So how should pneumatic winch operators operate more规范? Let me briefly introduce it to you. 1. Pneumatic winch operators must undergo specialized training and hold a certificate after passing the examination. 2. Preparations before operation: 1. Check whether the base of the pneumatic winch is securely fixed, whether all the fastening bolts of the winch are complete and well-fixed, and check for any dangers or abnormalities around the winch and the top support. 2. Check whether the pneumatic winch's braking device is intact; the brake band must be complete without cracks, and the remaining thickness of wear must not exceed the limit. The surface of the brake wheel should be smooth and flat, without obvious grooves or oil sludge; all bolts, pins, shafts, pull rod bolts, and back caps should be complete. 3. Check the steel wire rope: it should be free of bends, hard injuries, knots, and severe rust, with a diameter that meets the requirements, and broken wires should not exceed the limit. The rope should be neatly arranged on the drum, without severe rope biting or climbing; the length of the wound rope should not exceed the allowed rope capacity; the hook head and protective rope should be intact. 4. Check whether the air pipe is intact and free of air leaks, and check whether the lubricating oil is sufficient (add about 2 liters of No. 46 air compressor oil inside the motor shell, and add 0.5 liters of lubricating oil in the oil mist device), adjust the needle valve of the oil mist device to ensure that the oil supply is 10 to 15 drops per minute under rated working conditions; check whether the air pressure is sufficient. 5. Check that the signal device is intact and has no failures; the signal must have both sound and light, with clear and accurate sound. 6. If any problems are found during the above checks, they must be dealt with immediately before starting the operation. 3. Starting the operation: 1. Turn the clutch handle to the "engaged" position. 2. Operate the distribution valve handle according to the arrow markings; pulling inward is for lifting, pushing outward is for lowering. 3. First, run the machine idly for a few minutes to check whether the braking mechanism is reliable and whether there are any abnormal sounds. 4. After confirming that there are no abnormalities, send out the starting signal. When a clear and accurate response signal is heard, operate the distribution valve to run in the lifting direction. 5. During the operation of the pneumatic winch, the operator should concentrate, pay attention to signals, and observe the steel wire rope. If an unclear signal is received, the operator should stop immediately to investigate the cause. 6. The operator must not chat with others during the operation of the pneumatic winch. 7. If any of the following situations are found during operation, the machine must be stopped immediately, and measures should be taken to address the issue before resuming operation: a. The steel wire rope is abnormally bouncing, the load increases, or suddenly loosens; b. There is a significant air leak at the joint surface of the cylinder cover and the joint surface of the housing and distribution valve; c. There are abnormal sounds, smells, or conditions; d. There are other dangerous situations; e. The fixed winch support or foundation is loose; f. There is severe rope biting or climbing. 4. Stopping: 1. As you approach the stopping position, turn the distribution valve handle to the middle position, and then operate the braking system to stop. The operator should stop accurately, strictly prohibiting over-winding or stopping in the wrong position. In special circumstances, if an emergency stop is needed, the distribution valve handle and braking system can be operated simultaneously. 2. When the pneumatic winch is stopped for a long time or the operator leaves the post, the intake valve must be closed. 3. During the handover, the dust and debris on the pneumatic winch should be cleaned, and the operation and maintenance situation of the winch during this shift should be clearly communicated to the next shift. The above is a brief introduction to the correct operation of pneumatic winch operators, hoping to be helpful to everyone. Friends are welcome to leave messages for consultation.
