Double hook electric hoist is a common lifting equipment, it is composed of reel, main lifting motor, reducer, fixed plate and two hook body, can be widely used in industry, construction, logistics and other fields. According to different types of double hook electric hoist, its lifting parameters, working level and applicable environment are not the same.

Lifting weight is one of the important indexes of double hook electric hoist. According to the actual demand, double electric hoist rated lifting weight can range from hundreds of kilograms to dozens of tons. In addition to the rated lifting weight, double electric hoist and lifting height, span and amplitude index, these parameters need to be used according to the environment and mission requirements to determine.

Double electric hoist work level is also the important factors influencing the choice. Different working levels determine the service life and safety of the double hook electric hoist. For example, the M4 class double hook electric hoist is suitable for heavy duty and frequent use, while the M3 class double hook electric hoist is suitable for light load and medium frequency of use.

The application of the double electric hoist environment also need according to the specific situation into consideration. Different environment to double hook electric hoist material, structure and performance have different requirements. For example, the double-hook electric hoist working in the humid environment needs to use anti-corrosion materials, and the double-hook electric hoist working in the explosive gas environment needs to take the corresponding explosion protection measures.

Different types of double hook electric hoist have different characteristics and advantages, the following are respectively introduced:

1. Two-speed electric hoist
Double speed electric hoist is a kind of common double electric hoist, which can adjust the speed of drum, according to the actual demand to meet the needs of different lifting tasks. Two-speed electric hoist generally uses M4 level, can withstand heavy lifting tasks. In addition, the two-speed electric hoist has the advantages of compact structure and easy operation, which is suitable for hoisting, loading and unloading, stacking and other fields.

2. Double frequency conversion electric hoist
Frequency conversion double hook electric hoist is a new type of double hook electric hoist, it uses frequency conversion speed regulation technology, can achieve accurate adjustment of speed up and down. Compared with the traditional double hook electric hoist, frequency conversion double hook electric hoist has a wider range of application and higher efficiency. At the same time because of the use of advanced control technology, frequency conversion double hook electric hoist can achieve higher safety.

3. Explosion-proof double hook electric hoist
Double explosion-proof electric hoist is mainly suitable for the lifting tasks of inflammable and explosive environment, it USES special material and structure design, to ensure that remain stable in high temperature and high pressure environment and security. Explosion-proof double hook electric hoist can be customized according to different lifting tasks, to meet the needs of various special environments.
