Overload:

The servo controller will prevent the lift from moving upward if loaded beyond the maximum capacity of the

G-Force® BX ILD. When an overload condition is sensed, the Overload indicator is illuminated and the lift is
prevented from moving upward. The lift may be moved down to allow for the safe removal of the load. Releasing and
reactivating the operator present switch resets the overload condition.

Limit Switches:

The G-Force® is equipped with both mechanical Upper and Lower Limit switches, located in the

Actuator assembly. When the Upper Limit switch is triggered, the upward motion of the lift stops quickly at a controlled
deceleration rate. The controlled deceleration rate guarantees the load cannot come off the hook. When the Upper
Limit is triggered, the lift will move down but not up. The lower limit is set so that a minimum of two (2) full wraps of
wire rope remain on the drum pulley at all times. When the Lower Limit switch is triggered, the downward motion of
the lift stops quickly at a controlled deceleration rate. When the Lower Limit is triggered, the lift will only move up and
not down.

Slack Switch:

The G-Force® is equipped with a pair of Slack Switches that sense tension in the wire rope and trips

when the wire rope develops slack. The switches are located inside the Actuator assembly. When the Slack Switches
sense slack in the wire rope, downward movement of the lift is stopped to minimize the amount of wire rope unwound
from the drum pulley. When slack in the wire rope is sensed, the lift will only move up but not down.

Remote Mount Handle (System Option):

The lifting device is capable of operating with the handle displaced from

the wire rope (not in-line with the wire rope). For example, if an end user has tooling that is too large for the operator
to safely reach and operate the handle in the standard position, remote mounting the handle is recommended. The
tooling must be mounted (and balanced) on the end of the wire rope, while the handle can be remote mounted. The
tooling

must

be attached to the end of the wire rope with a swivel assembly (supplied by Gorbel, Inc.). Failure to mount

the tooling with a swivel assembly can result in premature failure of both the wire rope and the coil cord. The remote
mounted handle is linked to the coil cord via extension cables and connectors. The handle operates exactly the same
as if it were mounted in-line. If the device is equipped for Float Mode, a load cell assembly is provided that must also
be mounted between the tooling and the end of the wire rope. The handle is linked to the load cell via an extension
cable and connectors. **The end user must supply Gorbel, Inc., with the required length of the extension cables such
that they can be safely routed and clamped to the tooling. Always include the distance for bends and turns when
providing the extension length.

CONTROLS INTERFACE FEATURES

Jog Switch Push Buttons:

The Jog Switch Buttons allow qualified personnel to replace the wire rope (load

cable) on the system. To effectively operate the Jog Switch Buttons, all electrical cables must be connected and
power on. Depressing the “Up” jog switch button will enable the motor and cause the system to reel the wire
rope into the actuator and onto the main pulley. Depressing the “Down” jog switch button will enable the motor
and cause the system to pay out the wire rope from the actuator and off of the main pulley. The handle and
operator present switch are not to be operated during use of the Jog Switch Buttons.

WARNING

The Jog Switch buttons are for system maintenance and load testing use only, and should not be
manipulated during normal operation of the G-Force® BX ILD. Operation of the Jog Switch buttons dur-
ing normal operation increases the risk of personal injury to the operator.
