What is the difference between a wire rope electric hoist and a chain electric hoist?

Both wire rope and electric chain hoists are divided into single-speed and double-speed. Single-speed is more commonly used. Chain hoists can be changed to double-speed through frequency converters, depending on personal needs. If it is difficult to select between the two, you can refer to the following characteristics to distinguish them. There is no difference between good and bad. You need to choose according to your actual situation to give full play to the performance of the lifting tools.

Both are electric hoists, and the main differences are the following four points:

1. The winding device of different wire rope electric hoists is a steel wire rope, which is rigid and prone to troughing when no load is present. When lifting small weights or transporting heavy objects to the support, it is easy to cause rope tangle problems. The winding device of the electric chain hoist is a chain, and the winding method is hinged. It has no rigidity and will not cause rope chaos.

2. The wire rope electric hoist is subjected to different forces. One side bears tension and the other side bears pressure during the lifting process. In order to avoid repeated folding and weakening the performance of the wire rope and ensure its service life, the direction of the wire rope winding on the drum and sheave must be consistent. . As a result, the side that bears the pressure is always in a state of compression, and the side that bears the tension is always in a state of tension. There is no need to consider this issue with the chain hoist. The winding direction of the chain on the sprocket can be set at will, which is highly flexible. And the structure is reasonable, which is also the reason why the overall size of the electric chain hoist is small.

3. Different durability. The steel wire ropes equipped with electric wire rope hoists are often relatively thin, and the equipment itself may work in extreme environmental conditions, such as moisture, acid mist, alkali mist, and high temperatures. Thin steel wire ropes are prone to breakage. This can easily cause accidents. The cross-section of the electric chain hoist is relatively large, and its core materials are often selected to be high temperature resistant and anti-oxidation, which are not easy to change in harsh environments.

4. Different advantages Under the same specifications, the electric chain hoist has advantages in terms of lifting height, running distance, positioning, etc. At the same time, it is easy to modify, has a long service life, has low potential risks, and is more suitable for severe weather. In comparison, the electric chain hoist has advantages, but the wire rope electric hoist also has its own characteristics and scope of use, so you can choose according to your actual situation. Take my house as an example. Wire rope electric hoists and chain electric hoists each have their own merits. The best-selling wire rope electric hoist is the cd1 electric hoist, which can be customized with specifications of 1 ton, 2 ton, 3 ton, 5 ton, 10 ton and above. And you can customize the extended version, double lifting points, special version for freight elevators, low headroom, etc. according to your needs!
