1 Ton Hand Chain Block Hoist

1. Product Introduction:

1 ton Hand Chain Block Hoists are also known as chain hoists, inverted chains and manual hoists.

It is a lifting machine used in conjunction with the three-timber frame or herringbone frame. Its lifting capacity ranges from 0.5 to 20 tons, and there are eight types according to different lifting capacities: 0.5, 1.0, 1.5, 2.0, 3.0, 5.0, 10 and 20 tons.

The lifting height is determined by the chain length and the height of the herringbone, generally within 5 meters. In addition, the hand chain hoist can also be used to tighten the pole cable wind rope and tighten the ropes binding the components during component transportation.

The chain hoist can be used in vertical, horizontal and inclined directions. When lifting, hang the hook at a fixed height, first pull the chain with your backhand, loosen the lifting chain so that the quantity has the maximum lifting distance, and then slowly tighten it to lift the heavy object.

It is convenient and quick to use, and has a wide range of application scenarios. It is suitable for short-distance lifting of various small equipment and goods. It is a small and light lifting equipment. It is suitable for short-distance lifting of small equipment and goods. The lifting weight generally does not exceed 10T, and the maximum up to 20T, and the lifting height generally does not exceed 6m.

Compared with the chain hoist and the lever hoist, the power supply is an inevitable problem.

If there is no power supply outdoors, the electric chain hoist cannot be used, and the advantages of the lever hoist and the chain hoist are very obvious. Use it anytime, anywhere.

2. Parameters:

3. Component:

The shell of the 1 ton Hand Chain Block Hoist is made of high-quality alloy steel, which is sturdy and wear-resistant and has high safety performance.

When the chain hoist lifts the heavy object upward, pull the manual chain and the hand sprocket clockwise to rotate, and when it descends, pull the hand zipper chain counterclockwise, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the pawl, and the five-tooth long shaft Drive the hoisting sprocket to run in the opposite direction, so as to smoothly drop the heavy objects.

1 ton Hand Chain Block Hoists generally use ratchet friction disc type one-way brakes, which can brake by themselves under load, and the pawls mesh with the ratchets under the action of springs to make the brakes work safely.

4. How to choose to buy a hand chain hoist?

The hand chain hoist is selected according to the final component that needs to be lifted. For example, the heaviest component is 3 tons. You can choose a 3-ton hoist or a 1.5-ton hoist and a 2-ton hoist, depending on the existing equipment at the time.

5. Applicable Environment:

1 ton Hand Chain Block Hoist is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. to install machines and lift goods, especially for open-air and no-power operations, showing its superiority.

6. Maintenance method

(1) After use, the hoist should be cleaned and coated with anti-rust grease, and stored in a dry place to prevent rust and corrosion of the chain hoist from moisture.

(2) Maintenance and repair should be carried out by those who are more familiar with the hoist mechanism. Use kerosene to clean the hoist parts, and add butter to the gear and bearing parts to prevent those who do not understand the performance principle of the machine from disassembling and assembling at will.

(3) After the hoist has been cleaned and repaired, no-load test should be carried out to confirm that it works normally and the braking is reliable before it can be delivered for use.

(4) The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and the phenomenon of heavy objects falling.

(5) The rollers of the left and right bearings of the hoisting sprocket of the chain hoist can be adhered to the inner ring of the bearing that has been press-fitted on the journal of the hoisting sprocket with butter, and then installed into the bearing outer ring of the wall plate.

(6) When installing the braking device part of the chain hoist, pay attention to the good meshing between the ratchet tooth slot and the pawl part, and the control of the pawl by the spring should be flexible and reliable. The ratchet wheel and friction plate are pressed on the brake seat, and the hand sprocket is rotated counterclockwise, and there should be a gap between the ratchet wheel and the friction plate.

(7) For the convenience of maintenance and disassembly, one link of the bracelet is an open chain (welding is not allowed).

(8) During the process of refueling and using the chain hoist, the friction surface of the braking device must be kept clean, and the braking performance should be checked frequently to prevent the heavy objects from falling due to the failure of the braking.
