ComponentElectric Chain Hoist
The natural partner to a jib crane or monorail: compact, economical, simple to maintain.
Where it's preferred
At low and moderate tonnage — especially on jib cranes serving a single station and on fixed-route monorail lines — a chain hoist is the natural choice. Being compact gains lifting height in low-ceiling spaces.
Assembly workshops, maintenance lines, packaging and food facilities are typical areas of use.
Chain maintenance
Two things matter on a chain: elongation and wear in link diameter. Measurements are taken over a set number of links and compared against the original dimension.
Chain lubrication shouldn't be neglected; a dry chain both wears fast and eats into the guide. Never add links from a different manufacturer or grade.
Technical points
| Topic | Assessment |
|---|---|
| Tonnage | Low to moderate |
| Lifting height | Limited by chain-box capacity |
| Building-height demand | Compact — an advantage under a low ceiling |
| Typical use | Jib crane, monorail, light overhead crane |
| Maintenance items | Chain elongation, guide, lubrication, brake |
| Replacement | The whole chain is replaced; links aren't added |
Technical terms
| Term | What it means |
|---|---|
| Calibrated chain | A chain manufactured to tight dimensional tolerances for lifting. |
| Chain box | The container the descending chain collects in. |
| Guide | The part that feeds the chain onto the sprocket at the correct angle. |
| Elongation | Permanent stretching of the chain under load — a discard criterion. |
Frequently asked questions
Can I shorten or lengthen the chain?
No. Chain length is manufactured to match the lifting height; cutting and joining isn't done. If the height needs to change, a chain of the correct length is fitted.
When does it fall short compared to wire rope?
When high tonnage, high lifting height or high hoisting speed is needed. In any of those three cases a wire rope hoist should be considered.
