The specific quality requirements for wire rope electric hoists can be summarized and summarized based on the content of the reference article. The following are the detailed quality requirements:

Pre installation inspection:

Before installation, a comprehensive inspection of the wire rope electric hoist is required, including whether the accompanying documents are complete, whether the packing list, materials, and accessories meet the requirements.

Check the surface of the electric hoist for wear, rust, and other issues.

Installation of steel wire ropes and hooks:

The installation of steel wire ropes and hooks should be carried out according to the winding method specified in the equipment technical documents.

The fixing method of the steel wire rope head, the drum body, and the hook, as well as the tightening degree of the fasteners, should strictly follow the technical document standards.

Comprehensive inspection after installation:

Is the electrical device of the electric hoist suitable for the type of current and working voltage at the installation location.

Whether the action of the limit device is correct, flexible, and reliable.

Is the electrical circuit connection correct and reliable.

The locking buckle of the steel wire rope must be firm.

Have all lubrication parts been filled with sufficient lubricating oil separately.

When selecting power cables, it is necessary to ensure that the power supply at the motor inlet is not less than 90% of the rated voltage.

Quality requirements for equipment and equipment:

The equipment and equipment used should comply with the current national standards and have equipment nameplates.

The packaging is complete and the sealing element should be well sealed.

The quantity and specifications of the unpacking inventory should meet the design requirements, and the accessories and spare parts should be complete.

The technical documents of the product should be complete, and the appearance inspection should be free of damage, deformation, and rust.

The intact standard for electric hoists:

The components of the main and auxiliary machines are complete and meet the quality requirements.

The equipment nameplate is complete and clear.

The track is stable and reliable, and there is a safety barrier at the endpoint. All connecting components and machine base bolts are complete and tightened.

The operating space of the electric hoist should be unobstructed, the track should be flat and clean, and the body should have good anti-corrosion paint.

There is no oil leakage in the gearbox.

Good lubrication, smooth operation without noise or bumps.

The electrical insulation of the electric hoist is good, and the operating speed and lifting speed of the hook meet the requirements.

The lifting capacity reaches the nameplate output or rated capacity.

Selection of steel wire rope:

Select the appropriate steel wire rope specification based on the tonnage of the electric hoist. For example, it is recommended to use 197-5.0 steel wire ropes for 0.5 ton gourds, and 637-7.4 or 19 * 7-8 steel wire ropes for 1 ton gourds.

Technical document requirements:

The quality certificate, installation and user manual, and other factory technical documents should be complete.

There are equipment record cards, maintenance and test records, and drawings of damaged parts and accessories.

Environmental adaptability:

For special purpose electric hoists used for lifting molten metal, fragile, dangerous, and valuable items, the working level of the lifting mechanism should be appropriately raised, and necessary safety protection measures should be added.
