HCA Overload Light
Indicator light illuminates when HCA detects crane overload.
Boom down, extend out and hoist up functions are disabled
when light illuminates.
Anti-Two-Block/Jib Overload Light
Indicator light illuminates when a two block or jib overload
conditions detected. On Jib equipped units an Audible Alert
sounds when two-block or jib overload conditions are
detected.
Key Override Switch
Turn key switch to enable or disable HCAS, jib load limiting
device, and ATB override. Some units may be equipped with
an optional manual reset valve which does not have an
override key switch.
Override Button
With the override key switch in the on position, depress the
button to override the HCAS jib load limiting device and the
ATB system. Do not use the override to continue lifting
operations in an overload or two-blocked condition.
Load Chart
This chart shows capacities of crane at various operating
areas and hoist capacities with appropriate reeving.
Boom Angle Indicator
Located on either side of the base boom section and used to
determine main boom angle with respect to horizontal. For
reference only.
Boom length Indicator
Located on either side of the second boom section. The
letters on the intermediate boom lengths correspond to the
letters on the load chart. The length indicators are used to
define boom length and with the load chart and load radius
are used to determine the maximum loads that may be safely
lifted. Actual radius must be measured from the centerline of
rotation.
Outrigger Status Indicator
The Outrigger Status Indicator is part of the Outrigger
Monitoring System and communicates to the operator the
position of the outriggers and stabilizers. The Outrigger
Status Indicator is a bi-color LED located at each control
station. When power is on and the outrigger and stabilizer
beams are extended to a point at which they provide
maximum stability (stabilizers beams shall be fully extended
on cranes equipped with Rear Stabilizer Out and Down
(RSOD)), the Outrigger Status Indicator illuminates constant
green, indicating a lift can be made. If power is on and one or
more outrigger or stabilizer beams are not extended to a
position which provides maximum stability, the Outrigger
Status Indicator flashes red, indicating a lift should not be
made. If the Outrigger Status Indicator illuminates constant
red, there is a fault in the OMS.
