Chain hoists are hoisting equipment without power supply and will not be affected by power failure, but electric crane are hoisting equipment that uses household 220V voltage as the power source.
First of all, the power outage will affect the lifting work of the staff and reduce the work efficiency.
However, users who buy hoist cranes are worried that after the power outage, the heavy objects lifted by the crane will be affected?
Will they fall rapidly from the sky?
The answer is no.
Each small indoor crane has an automatic braking device. Once the power is off, it will automatically brake to prevent heavy objects from falling. However, if the goods are hung in the air after a power failure, the lifting pressure of the crane will be increased.
When we need to manually slide the wire rope to make the heavy objects fall to the ground safely and smoothly, we also need to turn off the power switch on the socket, so that even if there is a sudden call, the hoist will start by itself, and there will be no accident when lifting heavy objects. condition.
After the call is made again, we turn on the power of the plug-in row and the indoor small crane, and test the load first to ensure that the motor is running normally before working.
