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

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.

Three phase cheap wire rope hoist

Three phase electric hoist in the use of safety and technical conditions before checking hook, wire rope, reducer and other consumable parts. When in use, prohibit persons from portable electric hoist entering the danger zone and sent people hoisting care. three phase electric hoist placed when lifting or bundled items must be standardized in line with lifting requirements, the brakes, the safety device failure, the next hook nut locking device is damaged, rope and other damage to be scrapped prohibited lifting devices operation. Hanging objects tied, hanging strong or imbalance may slip, not for lifting operations are not padded edges between objects and cheap wire rope hoist. Unable to see the sites, not for lifting operations suspended matter the situation and command signals. In stoppage or rest, get the hanging objects, hanging baskets, spreader and cable hanging in the air. Allowed to press the two make three phase electric hoist in the opposite direction of movement of the flashlight electric wire rope hoist door button. After the completion of the work must always pull the brake power, cut off the power. Dynamic load test based on the weight of the rated load, as repeatedly lift and move around the test, checking the mechanical transmission parts After the test, the electrical part and the connecting portion is normal and reliable.

Manual hoist as an upgraded version of the fixed pulley

Manual hoist as an upgraded version of the fixed pulley, fully inherits the advantages of fixed pulley, while using a combination of reverse backstop brake reducer and chain pulley blocks,lever hoist manufacturers symmetrically arranged two spur gears turning structure, simple, durable and efficient.
Manual hoist by hands and pull chains, bracelets wheel rotation, the friction plate ratchet, brake pressure into one common rotating seat, the long axis of the tooth will turn the sprocket tooth spline hole short axis and gear. This means lifting sprocket holes on the splines on the drive gear lifting chain, so as to enhance the smooth heavy.wire rope electric hoist Using one-way ratchet friction disc brakes, brake under load on their own, with the ratchet pawl engagement under the action of the spring, the safety brake.

Liftech Equipment Manual Hoist usage rules

Liftech Equipment Manual Hoist stayed overload use is strictly prohibited. Do not operate with a power other than human. Before using the parts required to confirm intact,cargo lashing transmission parts and lifting chain oiled, idling normal. Liftech Equipment Manual Hoist lifting hook before checking whether hanging down firmly, lifting chain should be hung vertically, not a wrong twist of chain link, double under hook rack chain not flip.
Liftech Equipment Manual Hoist operator should stand on the same plane with the bracelet round hands pulled the chain to make bracelets wheel rotates clockwise, you can make the weight rise;small electric hoist reverse hands pulled the chain, the weight can slowly decline. When lifting weights, is prohibited personnel action to do any work or walk under a heavy object, in order to avoid a major accident. In the lifting process, regardless of the weight up or down, drag chain hands, the force should be uniform gentle, do not use too much force, so as not to hand chain jumping or snap ring. When the operator is found hand-pull tension greater than normal, you should immediately stop using it. Prevent damage to the internal structure, to prevent falling objects accident. After heavy to be safe and secure landing,manual lever hoist then remove chain hoists under the hook. Use Liftech Equipment Manual Hoist finished, gently, in a dry, well-ventilated place, apply lubricant put away.
