Lever hoist Handling Precautions

When the ratchet lever hoist is used to enhance the loading hoists, hoist from the weight should be reduced to 1/3 of nominal weight.
Lever hoist must be checked before using the case if all the fastening screws are tight, not loose.
Lever hoist has been wiped clean penetration supporting rope and wire rope clamp, then pulled forward or backward Shouben handle, depending on whether the action is normal.
Lever hoist is used to enhance the weight of the human, not any longer operating handle.
Lever hoist operation should handle the freedom to let the rest follow, not jammed.
Lever hoist must be selected according to the size appropriate tonnage hoist load.
Not use lever hoist overload.
Lever hoist shall be illegal to use.

lever hoist high work efficiency

 lift hoist is suitable for construction of the line tight line, adjust the sag, cable and other work in the power, shipbuilding, transportation, construction, mining, telecommunications, communications and other sectors of equipment installation; lifting small items.
 lever hoist mechanical traction, Japan NGK lever hoist especially in small workplaces, outdoor, aerial, and a variety of different angles of traction. More unique advantages;
 lever hoist the main selection of high-strength magnesium alloy material, the chain of high-strength special steel material, with easy to use in the design and use, safe, reliable, reasonable structure, beautiful shape.
 lever hoist maintenance is simple, durable, small lever force, high efficiency, small volume special, special light weight, easy to carry special features.
 lever hoist lifting industry is prohibited ill personnel to operate using. What is the relevant information, please read carefully.
Recently, together with the crane collapse occurred in Anning District of Lanzhou City. Important cause of heavy machinery accidents are frequent lifting equipment "sick job", not inspection, unlicensed operation and other security vulnerabilities.

Lifting machinery such operations are very grateful to the technical content, our operators need to have what conditions?

Article: Various cranes should be installed, indicating the hoist manufacturers of signs and, if necessary install winch limit
, A load controller, interlock switches and other devices should be placed walking track cranes and rail clamp stopper, try hanging should be checked before use.
Article: wire rope on the drum must be neat, tail card prison, work at least three times over reserved.
Article: Do not arbitrarily change the performance of the crane.
Article IV: the operation must obey the signal commanding officers, the signal is unknown or may cause an accident should be suspended operations.
Article: When lifting, lifting objects under someone to stay and can not walk.
Article: lifting objects should pull slip rope, speed should be uniform, smooth, prevention of sudden braking and changes of direction, lifting objects, should be more than 0.5 meters above the barrier, should be low speed fall gently to prevent dumping.
Article: When lifting an object, the object is prohibited to stand.
Article VIII: establish sound crane maintenance, periodic inspection, operating system security, and education-related personnel seriously implemented.
Article IX: bridge crane should be located chauffeur-driven, there is a person responsible for the hook and directing (the need for operating permits). Driving without a license is prohibited and conductor.
Article X: Cranes workplace have sufficient lighting and smooth lifting channel. Prohibited from hanging objects across the top of the head.
Article XI: significant parts of the crane's maximum weight marked prohibited overload.
Article XII: the crane work, prohibit staff from top to bottom, are not allowed to engage in repair work, banned from a crane over to another crane up except shut down for maintenance, the prohibition on track to leave.

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.

Lever hoist features

All structural steel lift hoist
Super alloy chain lever hoist
Full rotation of the gear lever hoist
Lever hoist gear and rotating the shaft has bearings or bushings
Lever hoist product surface after spray
Alloy lever hoist hook professional products to meet the overload
Lever hoist products to meet 150% of rated load weight
Lever hoist is the use of aluminum alloy chain lever hoist, the most important feature is the small, labor-saving, easy to carry.
Lever hoist is an easy to use, easy to carry the manual lifting, mainly for use when lifting and lateral traction, field operations officer for the power cable installation or aerial tight line.

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.
