Anti-corrosion electric wire rope hoist

The anti-corrosion electric hoist is an electric wire rope hoist with a certain anti-corrosion ability such as the outer of the hoist, the motor, and the electrical device.

It is suitable for places with anti-corrosion requirements for electric hoists such as electroplating and pickling.

Advantages of anti-corrosion electric wire rope hoist

• The unique double-rope structure makes the force more reasonable and the operation more stable;
• The design of the in-line hook is used in combination with the user's isolation measures, and the anti-corrosion effect is better;
• More choices for motor and electric control box protection grade IP44, IP54, IP55, IP56;
• The shot blasting treatment on the surface of the hoist shell reaches Sa2.5, and the paint is all made of epoxy zinc-rich anti-corrosion paint, which has stronger anti-corrosion ability;
• Galvanized steel wire rope, stainless steel wire rope and more anti-corrosion accessories are available;

Anti- corrosion of wire rope

In order to ensure the quality of the steel wire rope, the surface of the steel wire galvanized layer should be smooth, complete, even and firm. Hot-dip galvanizing will reduce the mechanical properties of the steel wire. Galvanized steel wire ropes with high strength and corrosion resistance are required, and electro-galvanized steel wires are mostly twisted. Hot-dip galvanizing relies on physical thermal diffusion to form a coating. First, an iron-zinc compound is formed, and then a pure zinc layer is formed on the surface of the iron-zinc compound. There are two methods of galvanizing galvanized steel wire rope—multi-wire continuous hot-dip galvanizing and electroplating.

Apply a certain amount of anti-corrosion materials

Apply anti rust grease to the surface of the electric wire rope lift gearbox, coating the layer of barium petroleum sulfonate material to the exposed surfaces of threads, also with calcium based rust preventive grease and other lubricants. Add inner bearing grease to prevent rust. The application of these has a very effective protection for electric wire rope hoists.

Lubricate the wire rope regularly

It is necessary to oil a wire rope that is in constant operation motion. The hemp core of the new wire rope generally contains 12-15% of the grease, while the scrap wire rope only contains 2.4% of the grease in the lost part. The rope end of the same wire rope, even without the pulley, still contains 12.7-14.5% grease. The test shows that in the later stage of the test, the broken wire of the oiled wire rope is about half of the broken wire of the unoiled wire rope. Frequent oiling can effectively prevent the corrosion of the electric wire rope hoist.

Galvanized or Aluminized

For wire ropes used in the harsh environment but with relatively less movement, it is usually adopt special coating to anti-corrosion, such as galvanized and aluminized can be used optionally.

When exposed to air, the galvanized or aluminized surface of these wire ropes forms zinc hydroxide and aluminum hydroxide, which effectively prevents the corrosion of electric hoist wire ropes.

The coating can be galvanized and aluminum-coating, etc. The galvanized layer can be divided into a thin layer and a thick layer of galvanized wire rope. When used in a severely corrosive environment, aluminized steel wire rope is more corrosion-resistant, wear-resistant and heat-resistant than galvanized steel wire rope.
