The protection level of electric hoist for group hoist was originally divided in this way.
Group crane electric hoist is mainly used for simultaneous lifting of multiple units. Therefore, we should pay more attention to its safety level. Today, let us understand the protection level of group crane electric hoist. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system.
Group crane electric hoist is equipped with a wireless remote control, no line operation handle is required, but in special circumstances, the group crane electric hoist will have a wireless remote control and an operation handle, because two chain electric hoists can be used at the same time and it can be used separately. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system.
The safety device of group hoist electric hoist adopts electromagnetic brake, mechanical load brake, hook and safety tongue, reverse gear protector, limit switch and emergency stop switch. It is more convenient and effective to protect your operation safety. The protection grade of the electric hoist is IP54. The mechanical safety load status of the group hoist is divided into four levels: light, medium, heavy, and overweight.
The life and safety guarantee of electric hoist depend on its operating level. The protection level is IP 54, IP is the logo letter, 5 is the first mark number, No. 4 is the second mark number, the first mark number indicates the level of contact protection and foreign body protection, and the second mark number indicates the waterproof protection level.
The above points are the introduction of the protection level of the group hoist electric hoist. When buying large clamps, you must ask the manufacturer for each parameter group to improve the load-bearing capacity of the electric hoist. I hope to help you, lift the lifting industry for more than ten years, have rich production experience, if you have any questions or purchase intentions, welcome to consult and release, we will serve you wholeheartedly.
