Pneumatic winches in our daily life require professional personnel to operate, so how to operate pneumatic winch drivers should be more standardized, let me give you a brief introduction below.

 

1. Pneumatic winch drivers must undergo special training and be certified to work after passing the examination.

2. Preparation before operation:

1. Check whether the base of the pneumatic winch is firmly fixed, whether the fastening bolts of each part of the winch are complete and well fixed, and check whether there are any dangers and abnormalities around the winch and the top side.

2. Check whether the brake device of the pneumatic winch is intact. The brake belt must be intact and free of cracks, and the excess wear thickness must not exceed the limit. The surface of the brake wheel should be smooth and flat, without obvious groove marks, and no sludge; all bolts, pins, shafts, tie rod bolts and The back cap should be complete and complete.

3. Check the wire rope: it is required to be free from bending, bruising, knotting and severe corrosion, the diameter meets the requirements, the broken wire does not exceed the limit, it should be neatly arranged on the drum, and there is no serious biting or climbing phenomenon; the winding rope length shall not exceed The allowable rope capacity is stipulated; the hook of the rope end and the protective rope should be intact.

4. Check whether the air duct is intact, whether there is any air leakage, check whether the lubricating oil is sufficient (add about 2 liters of No. 46 air compressor oil in the motor case, and 0.5 liters of lubricating oil in the lubricator), adjust the needle valve of the lubricator Its oil supply is 10 to 15 drops per minute under rated working conditions; check whether the wind pressure is sufficient.

5. Check the signal device, etc. should be intact; the signal must have both sound and light, clear sound, accurate and reliable.

6. After passing the above inspection, it is found that the problem must be dealt with immediately before driving.

3. Driving:

1. Pull the clutch handle to the "closed" state.

2. Operate the handle of the distribution valve and follow the arrow mark to pull it in to raise it, and push it out to lower it.

3. Drive idling for a few minutes first, and check whether the brake mechanism is reliable and there is no abnormal sound.

4. After there is no abnormality, a start-up signal will be issued. When a clear and accurate return signal is heard, operate the distribution valve and run in the lifting direction.

5. During the operation of the pneumatic winch, the driver should concentrate, pay attention to the signal, observe the wire rope, and stop immediately to find out the cause if an unknown signal is received.

6. The driver shall not chat with others during the operation of the pneumatic winch.

7. If the following situations are found during operation, the machine must stop immediately, take measures to deal with it, and operate after the processing is completed.

a. The wire rope jumps abnormally, the load increases, or suddenly loosens;

b. When there is obvious air leakage at the joint surface of the cylinder head cover and the joint surface of the casing and the distribution valve;

c. There are abnormal noises, smells, and abnormalities;

d. When there are other dangers;

e. The pillar or foundation of the fixed winch is loose;

f. Severe rope biting and rope climbing phenomenon;

Four, parking:

1. Approach the parking position, pull the handle of the distribution valve to the middle position, and then operate the brake system to stop. The driver should stop accurately. It is strictly forbidden to over-roll or stop not in place. Under special circumstances, when emergency braking is required, the distribution valve handle and the braking system can be operated at the same time.

2. When the pneumatic winch stops running for a long time or the driver leaves the post, the intake valve must be closed.

3. The dust and debris on the pneumatic winch should be cleaned up during the shift, and the operation and maintenance of the winch in this class should be clear to the next shift.

　　 The above is the correct operation content of the pneumatic winch driver briefly introduced by the editor, I hope it will be helpful to everyone. Friends are welcome to leave a message for consultation.
