7.5-10T DHP type electric chain hoist may cause automatic power off after continuous operation for a long time. This is because the overheating protection function of the group hoist electric hoist motor is working. At this time, the height may be reduced, and the motor needs to be cooled to continue working.
Group hoist electric hoist is also called synchronous electric hoist, because it can be used alone, or it can be synchronized to work up, down, and lateral movement at the same time, like this group electric hoist is more suitable for lifting heavy objects with long lengths. When moving these objects, the group hoist electric hoist is required to lift at the same time and the lifting speed is stable. At the same time, it is necessary for us to know the protection level of the group hoist electric hoist. The group hoist electric hoist is equipped with a wireless remote control and does not have a wire operation handle, but sometimes the group hoist electric hoist will have a wireless remote control and an operation handle, because in this way two chain electric hoist can rise and fall at the same time, Can also be used alone. The safety devices of group hoist electric hoist commonly use electromagnetic brake, mechanical load brake, hook and safety tongue, reverse protector, limit switch, emergency stop switch. Protect your operation safety more effectively. The protection level of the group hoist electric hoist is IP54. The safety load status of the group crane electric hoist machinery is divided into 4 levels: light, medium, heavy and overweight. The guarantee of the life and safety of the group hoist electric hoist is based on the establishment under the operating level. For example, the protection level is IP54, IP is the marked letter, the number 5 is the first marked number, 4 is the second marked number, the first marked number represents the protection level of contact protection and foreign objects, and the second marked number represents the waterproof protection level.
