4) Figure 4: Make sure the rope goes over the
stainless steel knob (no. 1). Then, push the
spring-loaded cam back against the rope
which will automatically hold a load if the
rope end is let go (no. 2).
5) Figure 5: As you pull the rope (no. 1), the
motor will engage and load will move.
IMPORTANT: It is necessary to pull the
rope HORIZONTALLY to get the load
started. To stop load movement, stop pulling
on rope (no. 2).
6) Stand about 1 m (3’) from the winch and pull
gently and horizontally on the rope to get the
slack until you feel the tension rising on the
rope;
7) Look at your set-up to make sure that the
winch anchor and the rope entry pulley are
aligned with the rope;
8) Check that the rope does not rub against
objects along the path;
9) Pull on the rope, the power will go up and
the winching will start.
3.4.2 Lifting
3.4.2.1 Load lifting chart
BEFORE ATTEMPTING TO LIFT A LOAD, IT IS IMPERATIVE TO EVALUATE
ITS APPROXIMATE WEIGHT.
When lifting a load, you may figure the minimal number of wraps required on the capstan drum
in order to move the load.
This chart is designed to help figure out the number of wraps you need to lift a load and also
allow its lowering. The friction on the capstan drum is relative to the size of the drum installed,
the number of wraps and the load weight, therefore too many wraps may prevent a load to
lower.
IMPORTANT NOTE: IF THE MOTOR STALLS WHILE LIFTING A LOAD,
YOU HAVE EXCEEDED THE RATED LIFTING CAPACITY. THEREFORE, YOU MUST
LOWER THE LOAD TO RELEASE THE TENSION ON THE ROPE AND INSTALL A BLOCK
AND TACKLE DEVICE TO INCREASE THE LIFTING CAPACITY BEFORE RESTARTING TO
PULL. DO NOT START UNDER TENSION OR YOU MAY DAMAGE THE MOTOR.
