OPERATING INSTRUCTIONS FOR THE RAPID LOWERING LUG-ALLs
The rapid lowering LUG-ALL models operate on the same basic principles
as the regular lowering LUG-ALLs but have an additional action rapid
lowering. A mechanism allows these models to lower four ratchet teeth
per full stroke of the handle in addition to the notch-per-cycle regular
lowering. The reliability and basic simplicity of the original unit is retained
but the greater speed and smoothness in lowering offers an operational
advantage. It is smoother because the starting and stopping of the load
is reduced 75%.
TO LIFT:
1. Set the reverse lever to hold the u-frame pawl
against the ratchet
teeth (Fig. 1 page 15)
2. Place rapid lowering “switch” in the “OFF” position (ON and OFF
positions are identified on the side of the main frame).
3. Apply handle pressure to lift one, two, three, or a full stroke on the
handle (four ratchet teeth).
TO LOWER: (requires load of 15 lbs. or more)
1. For regular lowering (one ratchet tooth-per-stroke-of-the-handle) use
the instructions on the previous page
plus placing the rapid lowering
“switch” in the “OFF” position.
2. For the rapid lowering (four ratchet teeth-per-stroke-of-the-handle) the
same as for regular lowering except with the rapid lowering switch to
the “ON” position.
IMPORTANT: When using rapid lowering the operator should position
himself in such a way that he can control the torque of the handle through
the full travel of the arc, which is four times longer than with the regular
lowering. When first engaging rapid lowering the first stroke of the handle
may lower from one to four ratchet teeth depending on the cam position.
Following strokes will lower four ratchet teeth.
FREE RELEASE: (will not operate under load)
The same as for regular lowering models except with the rapid lowering
switch is in the “OFF” position.
NOTE: See Handle and Rigging sections for other important
information.
