[16] DISCONNECT SWITCH
CAUTION
Be sure to place this switch in the "
ＯＮ
" position. Use this switch temporarily only in the
case of preventing unexpected startup of electrical equipment during inspection and
maintenance.
Use this switch to turn off the battery power supply to prevent
unexpected startup of electrical equipment during inspection
and maintenance.
•
OFF: The battery power supply is turned off and no
electricity flows through all the electrical systems.
•
ON: The battery power supply is connected.
[17] OVERRIDE SWITCH
Override switch has a function to disable the moment limiter.
When this switch is turned ON, the crane does not automatically stop with the moment
limiter and is very dangerous. Any crane operation in such conditions may result in
dropping of hoisted load, breakage of crane boom, and/or machine tipping, and may cause
a serious accident resulting in death or serious injury.
Use this switch only when the moment limiter, which detects the crane conditions, fails or
a load test of the crane is conducted. Key for the switch must be detached during normal
operations.
In particular, never perform the following uses.
•
Never wind up the hook when hoisting loads.
Even if the weight of hoisted load exceeds the rated total load, the moment limiter cannot
detect it, and could result in dropping of the hoisted load, boom breakage or machine
tipping due to cutting of the winch wire rope.
•
After the moment limiter detects that the rated total load is exceeded during crane
operation and automatically stops the operation, do not perform hoisting operation, boom
lowering operation and boom extension operation while the operation stop function is
cancelled by turning this switch to the "ON" position. Such operation may cause boom
breakage and machine tipping.
•
Use the hook storage switch when storing the hook. If this switch is turned ON to perform
hook hoisting operation, automatic stop is not made in an over winding condition.
