When using hydraulic hoists, several key points need to be noted to ensure safe and efficient operation. Here are some important considerations:

Pre-operation Checks

Equipment Condition: Conduct a thorough inspection before use to ensure the hydraulic hoist is well-maintained and free from damage. Check the hydraulic system, electrical system, mechanical system, and safety protection devices for proper functioning. Verify the stability of the hoist.

Hydraulic Oil: Ensure that the hydraulic oil is sufficient by checking the oil level through the oil tank level window. If the oil level is low, add oil using a fuel filter and the same brand and type of hydraulic oil.

Operational Procedures

Steady Operation: When lifting and lowering heavy loads, operate at a uniform speed to avoid sudden changes in direction or abrupt acceleration or deceleration, which can cause the load to sway or generate inertial impacts.

Load Information: Before lifting, ascertain the weight and center of gravity of the load to select the appropriate lifting method and equipment.

Command and Coordination: During lifting operations, operators need to coordinate with other personnel, especially with a commander, to ensure smooth and accurate lifting or lowering of the load.

Safety Requirements

Clear Signals: Ensure that command signals are clear and comply with regulations.

Secure Suspension: When suspending loads, ensure that the angle between suspension ropes is less than 100 degrees to avoid excessive rope tension. Use padding at the corners where ropes pass to prevent wear.

Obstacle-Free Area: Avoid operating during peak traffic hours to ensure no pedestrians or vehicles are in the vicinity. Properly position the hoist to prevent it from tipping or leaning.

Regular Maintenance: Perform regular maintenance and cleaning of the equipment to prevent impurities from entering. Replace hydraulic oil periodically to ensure proper functioning of the hydraulic system.

Environmental and Operational Considerations

Temperature Control: Prevent overloading at low temperatures and allow the hoist to warm up to the specified temperature before operation. Also, avoid operating the hoist at high temperatures, and regularly check temperature gauges.

Chemical Corrosion Protection: Take measures to reduce the impact of chemical corrosion on the equipment, especially preventing rainwater and airborne chemicals from entering the machinery.

Additional Safety Precautions

No Passengers: Do not allow passengers to ride on the hoist during operation or movement.

No Alcohol: Operate the hoist only when sober and not under the influence of alcohol.

Avoid Electrical Interference: Do not operate other electrical appliances in the same area while using the hydraulic hoist.

Weight Limits: Adhere to the hoist's weight limits and avoid overloading.

Emergency Handling

Immediate Stop: In case of abnormalities during operation, immediately press the emergency stop button and inspect the hoist.

Report Issues: Report any accidents or malfunctions to relevant personnel immediately.

First Aid: In the event of personal injury, provide first aid promptly and transport the injured person to a hospital as soon as possible.
