DANGER
Remedy
Over current due to
over voltage or low
voltage
Excessive inching or
plugging operation
(consecutive
impression of start
rush current)
Over current due to
over load
Operation exceeding
short time rating or
intermittent rating
Over current due to
open phase operation
Excessive inching
operation
Lead wire damaged at
assembling
Insufficient connection
at assembling
Main factor Countermeasure
Operate the electric chain
hoist at the rated voltage.
Do not perform excessive
operation.
Use the electric chain hoist
with a load less than the
capacity.
Check the short time rating
and intermittent rating.
Use the electric chain hoist
within these ratings.
The electric chain hoist
cannot lift a load in open
phase operation. When any
abnormality is observed,
stop the operation
immediately and check
the cause of open phase
operation.
Do not perform excessive
operation.
Be careful not to have the
lead wire caught when
assembling.
Connect the insertion
terminal securely at
assembling.
