Chain hoist

hand chain hoist high-level work, better safety performance, high reliability, low failure rate, chain sprocket run, easy to fall off or quit, the use of more stable. Electric chain hoists are widely used in mold, machinery manufacturing, warehousing, logistics, shipbuilding, bridge construction and other industries and factories and other special purposes.

Lever hoist structural features

A hand hoist gear: innovation symmetrical arrangement of high-speed synchronous gear; international standard gear steel double gourd durability than ordinary, more stable rotation, hand pull lighter.
2. lever hoist chain: higher strength chain; counterparts at welding fine, medium frequency induction hardened after compliance with the technical requirements of ISO3007-1984 international standard chain; adapt to sudden overweight job; hand zipper feel better; change ordinary gourd only vertical drop-down, from multiple directions, was pulling a 45 ° angle, the greater the range of adaptation.
3. Japan NGK lever hoist hook: high strength material foot hook, advanced alloys, so the fracture does not occur outside the bear overworked, but the gradual deformation, higher safety factor; hook at the new design, so that the goods are not will be decoupled.
4. lever hoist limit switch: hanging under the hanging limit switch parts, textile chain beyond to ensure safety.
5. hand chain hoist parts: the main components are made of high quality steel, the implementation of strict size, weight checks to ensure the performance of each component of the full play.
6 lever hoist body: slim design, innovative and generous appearance; ergonomic, light body work activities of small interface, wide environment.
7. Japan lever hoist spray: advanced spray treatment process, inside and outside are hanging plastic, use for longer list are new as ever.
8. lever hoist Housing: pressed steel housing, solid in significantly lighter.

Chain hoists - correct method of operation

1, the operation should first try hand chain hoist, when the weight off the ground, such as in normal operation, reliable braking. Can continue lifting.
2, the operator can not stand heavy objects on top of operating the job, nor will stay in the air after lifting heavy objects and left the scene.
3, the lifting process, forbids any person to walk or stand under the weight.
4 Do not use non-manual drive mode lifting heavy objects. Pull them when found, shall not increase the tension, stop using it immediately, check the weight of its five, he implicatedobjects, heavy weight exceeds the nominal weight, gourds and other parts for damage.
6, increase or decrease the distance shall not exceed the weight lifting height, to prevent damage to the parts.
7, is prohibited by more than two and two hoists while lifting weights.
8, a typical example of the operation in violation of safety rules, see Appendix A (Appendix tips).

General Precautions using chain hoists

1, each product must be accompanied by product use and maintenance manuals, production licenses and product certification mark.
2, the product should be clear, durable signs.
3, non overload or oblique lifting cranes. Ban hanging pull buried or heavy condensation on the ground.
4, hand chain hoist supporting points must be strong and stable.
5, hanging, tied with a rope and chain safety factor should be not less than 6.
6, is strictly prohibited under the rebate to the lifting chain hook lifting weights
7, do not allow throwing hoists.
8, the user may not change the original design of the product.
9, the replacement parts must meet the original design requirements.
