One：Definition：Chain hoist is a kind of manual lifting machinery that is simple to use and easy to carry, also known as “chain block” or “inverted chain”.
Two：Scope and method of use：It is suitable for short-distance hoisting of small equipment and goods, the lifting weight generally does not exceed 10T, the maximum can reach 30T, and the lifting height generally does not exceed 6m. The shell of the chain 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 function 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. Chain 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 function of springs to make the brakes work safely.
Three：Advantage：manual pulley hoist crane has the characteristics of safety ,reliability, easy maintenance, high mechanical efficiency, small bracelet tension, light weight, easy to carry and durability. It is suitable for factories, mines, construction sites, docks, warehouses, etc. It shows its superiority in the installation of the machine, the hoisting of the goods, especially for open-air and unpowered work.
Four：Features
one. In line with international standards, safe, reliable and durable.
two. Good performance and easy maintenance.
three. High toughness, small size, light weight and easy to carry.
Four. Small hand pulling force and high mechanical strength.
five. The structure is compact and advanced, and the appearance is beautiful.
six. Lifting goods in areas without power supply.
seven. Powerful.
Five：Notice：
First .Inspection: Inspection can play a protective role to some extent, because the inspection work before use can find the problems existing in the chain hoist, it can deal with the factors that affect the safety of operation and reduce the occurrence of failures.
Second.Easy maintenance: The performance of the chain hoist has a lot to do with the maintenance. If the performance is good, the probability of failure is small.Therefore, attention should be paid to the maintenance of the chain drive hoist to reduce the wear and tear between various components and avoid failures. It can make the user complete the lifting work smoothly.
Third. Operator: The hand chain hoist is a professional tool. For the operator, they must be familiar with the working principle and use of the chain hoist before taking up the job, which can not only improve the work efficiency, but also greatly reduce the damage caused by improper operation and increases the life of the chain hoist.
