Lifting tackle how to use in order to maximize the usefulness of
(1) When lifting tool wear around the electric chain block group, it should be noted rope pulley groove angle. In any case, the pulley groove angle may not exceed 4 ° ~ 6 °. Because, when the wire rope in the pulley groove angle is too large, the wire rope and the pulley groove side wear increased, on the other hand, is easy to slide the wire rope rope groove, so that the lifting operation can not be normal, or even accidents.
(2) to wear around the lifting gear or pulley block pulley rope pulley must comply with the requirements. Elected with a rope pulley diameter exceeding the requirements will exacerbate sheaves wear, but also to make rope wear and tear. From the weight of the block must be equipped with the appropriate thickness of the rope.
(3) block group were wearing around after use, take a test hanging, detailed examination of each part is good, whether the  friction between the friction or rope at each other, if wrong, should after adjustment to formally lifting.
Change (4) the direction of the force on a electric chain block, or at high altitude operations, without declaring the use of hook-type pulley to prevent decoupling. Such as the use of hook-type pulley, you should take protective measures. If, after a good hook to hang with a thin wire to hook mouth shut, so that the hook can not emerge; or using hook with Picasso plates, this hook is more convenient to use, in the hang hook, Picasso plate under the action of the spring to bounce the hook mouth shut.
(5) shall not be overloaded using pulley, the pulley when there are cracks or defects, shall not be put to use. Other parts, such as hooks, axles, pull boards flawed, does not meet the requirements, are not allowed to use.
(6) If the multi-door pulley which is in use only a few doors, its weight should be commuted from reduced accordingly, can not be based upon the original starting weight make.

Winch Snatch Block winding principle

For the single winding non rotating Winch Snatch Block  wire rope, must strictly abide by the principles above, otherwise easily lead to permanent deformation of wire rope; for multi-layer winding, rope rotation direction is decided by the drum rope groove direction, chain hoist 1 ton so as to lay the foundation for the next layer.
Steel wire rope winding drum mutual friction and the extrusion pressure is big, easy to produce the phenomenon of chaos rope, so we should select the wire rope diameter slightly smaller than the rope groove pitch and groove diameter, lashing cargo so as to increase the contact area between the wire rope and drum, reducing the friction force between the adjacent wire rope, so as to improve the steel wire rope life. Practice has proved, wire rope electric hoist wire rope diameter than the rope groove pitch  1%, contribute to the rope tightly, effectively eliminate the climbing rope, rope disorder phenomenon.
In the same diameter, number of wire rope strand diameter smaller, single wire becomes smaller, the flexible of the steel wire rope is good, can reverse bending force to overcome the wire rope good out of drum is also easy, wearing rope. While the coarser outer strand, Wire rope winchthe steel wire is thicker, can better abrasion resistance, mechanical damage, corrosion and extrusion pressure. Therefore, only when the two advantages combine well, is the quality of wire rope is really high performance.

Let the rope does not become the vulnerable parts of Manual Block

Steel wire in Manual Block  is wearing parts, if in the process of using improper use or maintenance is not in place,motorized chain hoist very willing premature can cause rope scrap, so what can delay or maintain the normal use of the steel wire rope? Eagle electric hoist manufacturers to disclose to you.
Firstly, the mechanism of wire rope bending fatigue, then analysis of spiral multi-layer winding drum so that the wire rope is how rolling and wear, illustrates the influence of wire rope diameter tolerance, put forward to the improvement, wire rope hoist suppliers finally to find the solution from the rope itself. Between the steel wire rope in winding rope mutual grinding produced Nick, lead to premature failure of wire rope. Strand wire rope outside more closely, mutual notch less. So we must put the wire rope has 6 edges or 8 edges cross section made of circular cross section in order to solve the problem. The forged display lifting equipments rope round section in bending machine and a multilayer test, the service life can be 2 times.

Chain Block lifting mechanism

We often say that the Chain Block lifting height differ in the lifting mechanism, the lifting mechanism of what is, what the specific differences,
Wire rope electric hoist lifting mechanism comprises a lift hoist motor through the shaft coupling through the reducer hollow axle driving drum rotation, so that the wire rope around the drum driven by a rising or falling hook device.
Lifting height H=6m, with a jaw coupling is connected to the motor shaft and reducer input shaft. H ≥ 9m is added in the intermediate shaft and the rigid coupling. H ≥ 18m, with support to strengthen the intermediate shaft rigidity, guarantee the smooth rotation.
electric hoist with trolley structure: motor, gear box, drum, steel wire rope, hook
Motor drive gearbox the drum is rotated winding wire rope, hook up and down

What is hand gourd?

Hand wire rope hoist suppliers  is a kind of easy to use, easy to carry the manual lifting machinery, suitable for factories, mines, construction sites, agricultural production and the dock, dock, warehouse, used for installing machinery, motorized chain hoist

‍ goods and the loading and unloading of vehicles, especially for open and no power work more show its important function. With each hand monorail car supporting the use of hand chain hoist, of the hand lifting transportation vehicles, for overhead monorail transportation or cantilever crane.

Five major characteristics of the hand chain hoist:

5 durable.‍

The structure and principle of manual hoist

Manual lashing cargo with a chain wheel, hand zipper, transmission machinery, hoisting chain and the upper and lower hook and other parts. The mechanical transmission part can be divided into the worm and gear transmission two. Due to the mechanical efficiency of worm gear type transmission is low, parts easy to wear, so rarely used now. single girder gear transmission has several models, in which HS is a manual chain block popular; type WA is improved on the basis of type HS; SBL is the use of new structure of transmission, high mechanical efficiency of it, but the weight ratio of HS type heavy some.

manual chain block structure principle of the heavy device: the one with the reverse check braking deceleration combiner and chain pulley.

Hand chain hoist

Hand chain hoist 1 ton can be used safety device, equipped with function of preventing overload protection, hoisting increase is too large can not only smooth action in order to ensure the safe use, but also can prevent the theme of damage.

Hand chain hoist assembly simple, precise machine and minimum generation hook spacing design makes this series products even in narrow working environment. Easy to install, without any adjustment.
