The group hoist electric hoist is a low speed electric chain hoist. The group hoist electric hoist is mostly used in equipment with relatively large hoisting length. Overall lifting can be carried out. It can achieve multiple ring chain electric trekkers to rise or fall, the error can be ignored. When the staff use the group hoist electric hoist, there are many blind spots in the understanding, here to explain to you the operation of the group hoist electric hoist: 1, many staff mistakenly think that the group hoist electric hoist can be assigned to the electric trolley for use In fact, this method is wrong, the group hoist electric hoist only needs to be hung. 2. The staff mistakenly believe that the group hoist electric hoist can be used alone. The group hoist electric hoist can also be used alone, but it will run slower than the general chain electric crane. Not only is it inconvenient to use, but also reduces the operating power, it is recommended not to use it alone. 3. The staff mistakenly believes that multiple sets of electric hoists using 20 tons of equipment, only need 4 sets of 5 tons of electric hoists can work normally. This statement is wrong. It is assumed that a 20-ton lifting equipment should require four 20-ton group hoist electric hoists. 4. After the daily work of the staff is completed, the lifting equipment is not fixed, and the group hoist electric hoist is used for lifting directly. This way of working is unsafe. The hoisting equipment hangs in the air for a long time, which will not only cause great danger, but also cause great harm to the group hoist electric hoist parts. In the use of group hoist electric hoist, there are many things that are not clearly stated, which leads to many misunderstandings in the operation of the user. We should summarize our shortcomings and improve our technical level after each operation is completed.
