When preparing the construction materials and confirming the operating conditions of the electric hoist, it is necessary to pay attention to multiple aspects to ensure its safe and efficient operation. Here are some key preparation and confirmation steps:

Preparation of construction materials

Main components:

The electric hoist is mainly composed of a gearbox (for walking and lifting), a spline shaft, a spline sleeve, a coupling, a drum, a casing, a motor (for walking and lifting), a steel wire rope, a limiter, a hook, an electrical device, and its components.

Specific material selection:

Aluminum alloy: used in the manufacturing of drums because it is a lightweight, high-strength material with excellent corrosion resistance. However, it should be noted that the wear resistance of aluminum alloys is relatively poor.

Preparation before installation:

For newly installed or dismantled electric hoists, they should first be tested several times without load to ensure that all components are working properly.

Confirmation of operating conditions

Safety operating procedures:

The electric hoist should be operated by a dedicated person, and the operator should understand the structural performance of the electric hoist and be familiar with safety operating procedures.

Overload test:

The newly installed electric hoist should undergo a 125% overload test before use, with the lifting object 100mm above the ground and a dwell time of 10 minutes.

Pre work inspection:

Before starting work, a forward and reverse rotation test should be conducted with no load to check the reliability of control buttons, limiters, rope guides, brakes, and other equipment.

When the electric hoist is working, it should lift heavy objects vertically and not be used under overload; It is strictly prohibited to lift heavy objects with a slope exceeding 10 ° and use them as towing tools.

Power system:

Including batteries and chargers to ensure stable power supply.

Control system:

Check if the control buttons and switches are flexible and reliable to ensure accurate control of the lifting and lowering of the electric hoist.

Suspension system:

Ensure that the wire rope and suspension components are intact and can safely suspend the load.

Maintenance inspection:

Regularly inspect the steel wire rope for any bending, deformation, corrosion, or severe wear. If any problems are found, they should be replaced in a timely manner.

Check if the limit switch is flexible and reliable, and should not be used frequently as a travel switch.

end-of-job:

After completing the work, the hook should be raised to a height of more than 2mm above the ground and the power should be cut off.

Operation frequency:

The operating frequency of the operating button should not exceed 60 times per hour to avoid equipment damage caused by excessive use.
