How to Suppress the Swinging of a Load
• Do not move the electric chain hoist with a load hung at one side of the Crane Saddle.
Otherwise the load swings and hits a person or object or drops to result in death or serious injury.
Prohibited
Swinging of a load makes it difficult and dangerous to move the trolley. The basics of operation are not to make a
load swing. To do that keep the following instructions.
● Do not lift a load in an inclined direction.
● Start slowly when traveling the load.
● Do not lift suddenly.
Even if you keep the above instructions, the lifted load may swing
at the start and the stop of the electric chain hoist.
Following operation can reduce the swing of the lifted load.
■
Operation
1) Press the Travel Button. (Fig. a)
2) When the trolley starts to move, the lifted load delays a bit. (Fig. b)
3) Release the button a bit before the time when the lifted load
swings to the center position.
4)
When the lifted load comes to the position just beneath the electric chain
hoist, press the button again and continue to travel the load. (Fig. c)
