3.1.2
Operation
Should the SKY LOCK brake engage due to an overspeed condition, do not attempt to release or reset
it. Instead, remove men from suspended equipment, and lower it to ground or raise it to top by means
other than the hoist. Then contact your nearest Sky Climber representative.
SKY LOCK brakes may also be engaged by:
Turning manual trip lever
Sudden movement of men on platform or repeated vibration
In the event the Sky Lock brake engages for reasons other than overspeed, check condition of
equipment and wire rope below the Sky Lock brake. If satisfactory, operate hoist in up direction 5 to
10cm to relieve load on the Sky Lock brake, then turn reset handle as indicated on the Sky Lock brake
decal, until the Sky Lock brake resets. (See Figure 3.2)
Figure 3.2
WARNING: Failure to inspect and functionally check Sky Lock brake operation at the
beginning of each work shift in accordance with Section 5.4.2 could result in serious injury or
death.
3.2 EMERGENCY OPERATION - POWER FAILURE
In the event of loss of power, the hoist may be raised by using the option of hand crank, or lowered
using the Controlled Lowering Lever.
WARNING: Always Disconnect power at the pigtail connection before using the manual
crank or Controlled Lowering Lever, otherwise serious injury or death may result.
