When using an electric winch, comprehensive measures should be taken from the aspects of operating standards, equipment inspection, environmental adaptation, safety protection, and maintenance to ensure the safe and efficient operation of the equipment. The following are specific precautions:

1、 Preparation before operation

environment check

Site conditions: Ensure that the work site is flat, solid, free of obstacles or loose materials, and prevent winches from overturning or steel wire ropes from entangling foreign objects.

Space requirement: Check if there is sufficient operating space around the winch to avoid collisions between personnel or equipment during operation.

Environmental adaptability:

High temperature environment: Confirm that the motor cooling system is normal and avoid long-term overload operation.

Damp environment: Check the sealing of electrical components to prevent short circuits or leakage.

Corrosive environment: Confirm that the equipment's anti-corrosion coating is intact and take additional protective measures if necessary.

Explosive environment: Ensure the use of explosion-proof winches and compliance with relevant safety standards (such as mining explosion-proof certification).

Equipment inspection

Mechanical part:

Check whether the key components such as drum, wire rope, brake, reducer are intact, without cracks, looseness or excessive wear.

Confirm that the steel wire ropes are arranged neatly without any broken wires, knots, or twisting.

Check whether the braking system is sensitive and reliable, and whether the braking clearance meets the requirements (usually 1-3mm).

Electrical part:

Check if the power supply circuit is intact, without any damage or aging.

Confirm that electrical components such as control buttons, contactors, and limit switches are functioning properly and without any jamming or malfunction.

Check the insulation performance of the motor to ensure there is no risk of leakage or short circuit.

Safety device:

Confirm that safety devices such as overload protection, loose rope protection, and limit protection are complete and effective.

Check whether the safety facilities such as protective covers and guardrails are firm and reliable.

personnel training

Operators need to undergo professional training and be familiar with the structure, performance, and operating procedures of the winch.

Clarify the shutdown methods and emergency response measures in case of emergency.

2、 Precautions during operation

Standard operation

Start and Stop:

Before starting, confirm that there are no personnel or obstacles around the winch and issue a clear signal before starting.

Avoid frequent starting or emergency stopping to prevent motor overheating or mechanical shock.

Load control:

Overloading operation is strictly prohibited to ensure that the load is within the rated range.

When the load is increasing or decreasing, maintain a constant speed to avoid sudden acceleration or deceleration.

Wire rope management:

The steel wire ropes are arranged neatly on the drum to avoid tangled or biting ropes.

It is strictly prohibited to operate the winch in a relaxed state of the wire rope to prevent the wire rope from slipping out of the groove or breaking.

Braking system:

It is strictly prohibited to adjust the braking system during operation to prevent brake failure.

Ensure reliable operation of the brake during emergency braking to prevent equipment from losing control.

real-time monitoring

Pay close attention to the operation status of the winch. If any abnormal noise, vibration or temperature rise is found, stop the machine immediately for inspection.

Regularly inspect the wear and tear of the steel wire rope, and promptly replace the steel wire rope that meets the scrap standard.

Pay attention to the working status of electrical components. If any odor, smoke, or abnormal heating is found, immediately cut off the power for maintenance.

environmental adaptation

High temperature environment: Shorten continuous operation time, strengthen motor heat dissipation, and prevent motor overheating and burnout.

Low temperature environment: Preheat the equipment before starting to avoid brake jamming due to low temperature.

Damp environment: Regularly clean the water stains on the surface of the equipment to prevent electrical components from being affected by moisture and short circuiting.

Dust environment: Strengthen equipment sealing, regularly clean dust, and prevent mechanical component wear from worsening.

3、 Post operation maintenance

Equipment cleaning

Clean the dust, oil stains, and debris on the surface of the winch to keep the equipment clean.

Check whether the steel wire rope is contaminated with oil or corrosive substances, and if necessary, clean or treat it with anti-corrosion measures.

Component inspection

Check the lubrication condition of key components such as brakes and reducers, and promptly replenish or replace lubricating oil.

Check if bolts, nuts, and other fasteners are loose and tighten them in a timely manner.

Check if the electrical components are securely connected to prevent poor contact or short circuits.

Record and report

Record the running time, load condition, and maintenance content of the winch, and establish equipment files.

When equipment malfunctions or safety hazards are discovered, report them in a timely manner and shut down for maintenance. It is strictly prohibited to operate with defects.

4、 Safety protection measures

personal protection

Operators are required to wear personal protective equipment such as safety helmets, protective gloves, and non slip shoes.

It is strictly prohibited to perform maintenance or adjustment operations during the operation of the winch.

Warning sign

Set up clear safety warning signs around the winch, such as "Do not approach" and "Attention to safety".

Set up protective barriers or warning lines in hazardous areas (such as the range of wire rope movement).

emergency preparedness

Equip emergency equipment such as fire extinguishers and first aid kits, and regularly check their effectiveness.

Develop emergency plans and clarify the procedures for shutdown, evacuation, and rescue in case of emergency.

5、 Special scenario precautions

Mine operations

Explosion proof winches must be used and their explosion-proof performance must be checked regularly.

Strictly abide by the safety regulations of the mine, such as the principle of "no one is allowed to drive, and pedestrians are not allowed to drive".

Strengthen ventilation management to prevent gas accumulation from causing explosions.

field operations

Take rainproof and windproof measures, such as building protective shelters or using protective covers.

Strengthen equipment fixation to prevent the winch from overturning due to uneven terrain.

Equipped with a backup power source or generator to ensure the normal operation of the equipment in an off grid environment.

working at heights

Ensure that the winch is securely fixed to prevent equipment displacement due to vibration or wind.

Set up safety ropes or safety nets to prevent personnel or materials from falling.

Operators must fasten their safety belts and comply with the safety regulations for high-altitude operations.
