Manual chain hoists are also known as fairy hoists, chain hoists, inverted chains, caterpillars, manual hoists. Manual chain hoist is actually a kind of manual lifting machine that is easy to use and convenient to carry. About it, in terms of its own words, it will also be called "chain hoist" or "chain down chain". ".
Manual chain hoists are also suitable for short distance lifting of small equipment and goods. In terms of the lifting weight, they will not exceed 10T under normal circumstances, and the largest one is 20T, and the lifting height is generally not more than 6m. The shell material of the manual chain hoist is also a high-quality alloy steel. The machinery obtained from this type of material is characterized by its strong wear resistance and its relatively high safety performance.
When the manual chain hoist lifts up the heavy object, the manual chain and the bracelet wheel rotate clockwise, and when it is lowered, the counterclockwise hand zipper strip is moved, and the brake seat is separated from the brake pad. The ratchet is separated from the brake pad. Under the action of the static, the five-tooth long axis drives the lifting sprocket to run in the opposite direction, so that it can also smoothly lift heavy objects.
When the manual chain hoist lifts heavy objects upwards, the manual chain and the bracelet wheel rotate clockwise, and when the descender moves the hand zipper strip counterclockwise, the braking seat is separated from the brake lining, and the ratchet is in the action of the pawl. Under standstill, the five-tooth long axis drives the lifting sprocket to run in the opposite direction, so that, to a large extent, it can steadily reduce the weight.
The manual chain hoist is suitable for a series of installation machines and lifting goods in factories, mines, construction sites, docks, docks, warehouses, etc. Especially for the open air and no power supply operation, it also shows its superior performance. The chain in the manual chain hoist is made of 800Mpa high-strength lifting chain, and the material is generally 20M2, which is a chain with low wear and corrosion resistance.
