2.2.2 Controls
Refer to the central controlbox manual for a detailed description of the central control unit.
2.2.2.1 UP and DOWN SWITCH/LEVER:
2.2.2.2 SELECTOR SWITCH: (only electric powered hoist)
2.2.2.3 EMERGENCY STOP Button:
2.2.2.4 CONTROLLED DESCENT LEVER:
In the event of a power failure, the controlled descent lever, located on the end-side of the hoist can be
activated to manually release the hoist brake. This is done by pushing it towards the hoist-end.
(See Figure 2.1 & 2.2). The hoist will lower at a controlled speed of +/- 8.5 m/min. The controlled
descent lever shall only be activated when the power supply has been disconnected.
WARNING: Always disconnect power to the platform before activating the controlled
descent lever, otherwise serious injury or death may result.
2.2.3 CRANK HANDLE:
A crank handle is supplied with every hoist for raising the hoist and its load when there is a power failure
and upward travel of the Sky Climber hoist is required. Most of the time the distance over which
the hoist is to be raised is very limited : the main goal is to get the load back on the primary
suspension steel wire rope in order to un-load and re-set the Sky Lock.
How to use the crank handle:
Disconnect power supply plug (to central control box / air distribution yoke)
Remove the plastic safety plug in the center hole of the drive motor or brake unit.
Insert the crank handle on the shear pin of the shaft rear-end.
Hold the crank handle firmly whit one hand while lifting the brake manually.
Rotate the handle in the counter-clockwise direction to climb.
When stopping, release the controlled lowering lever before releasing the crank.
