WINCHING LIMITATIONS
There are several limitation that can affect the time duration, power
consumption and maximum weight a winch can move. A snatch block
will improve the winch’s performance. Make sure to follow all safety
and operation instructions from the snatch block’s manufacturer.
POWER
The maximum load the winch
can pull is diminished with each
additional layer of steel cable
around the winch’s drum.
Table 1 shows the maximum
amount of weight it can pull and
the length of cable remaining
on the drum.
Whenever possible, remove as much steel cable off the winch to pull
with the maximum power. Keep five wraps of steel cable on the drum
at all times to prevent the steel cable from slipping off.
Use a snatch block to move a heavier load that is close to the winch.
This will double the amount of line outside the fairlead and increase
the winch’s pulling power at close range.
LINE SPEED
The heavier the load, the longer it will take the winch to move the
load to the desired location. Consult Table 2 to determine how fast
the line will be drawn into the winch.
A snatch block will halve the line speed when pulling the load.
POWER CONSUMPTION
The winch requires more amps to
move a heavier load. Consult
Table 2 to determine the
amperage consumption based on
the load’s weight.
A snatch block increases a winch’s
pulling power without an increase
in amperage. Using a snatch block
can halve the power required.
