OPERATING INSTRUCTIONS
The Lever Block has been designed for manual operation only. It utilises a reciprocal operating
lever handle to drive a series of gears via a unique braking system to raise (or tension) and
lower (or release) a load both vertically and horizontally.
•
Place Lever Block into the required position to perform the lifting (or tensioning) operation,
ensuring the top hook is positioned correctly with the safety latch engaged as required
•
To raise the bottom hook without any load applied, use the Lever Block in the Free Wheel
mode, as shown in the instructions on the next page
•
While the unit is in Free Wheel mode, the load chain can be pulled through the device by
hand in either direction to position the hook in the desired location
•
Once the load has been connected to the lower hook, ensure the safety latch is engaged
correctly
•
Move the Select Lever to the Raise position
•
Operating the lever handle using a circular motion or a reciprocating (back and forth)
motion will begin lifting or tensioning the load
•
Start the lifting or tensioning process carefully, and once the load is taken up, stop and
check the integrity of the Lever Block, the load assembly, including any rigging gear, and
that the load path is clear before continuing the lifting or tensioning
•
Continually using a reciprocating movement will raise or tension the load while the Select
Lever is in the Raise position
•
If the handle movement is stopped at any time during the raising (tensioning) of the load,
the Lever Block will continue to hold the load automatically
•
To lower the bottom hook, first move the Select Lever into the Lower position
•
Take care before commencing lowering (or retracting) of the load, to ensure that the load
path is clear and unobstructed by obstacles or by persons near the work area
•
Operating the lever handle using a circular motion or a reciprocating (back and forth)
motion will lower the load
•
When raising or lowering a load, the desired operation is a smooth backward and forward
arm movement. Excessive speed is not recommended
•
Once load is in desired position, continuing the reciprocating movement will release the
tension of the load chain
•
After ensuring the load has been placed safely and securely, release the safety latch of the
bottom hook and remove it from the load
•
The unit can then be used in the Free Wheel mode to quickly move the lower hook to a
position where the Lever Block and chain can be safely removed from the job site
•
After removing the Lever Block from use, a visual inspection should be performed to cover
the points listed in the Pre-Start Check List previously described
•
Ensure the unit is stored correctly in a suitable secure location where unauthorised
persons do not have access
