WARNING
Rope:
The winch rope is wrapped around the winch drum and fed through the fairlead. The winch
rope is looped at the end to accept the hook’s clevis pin. Standard winch rope is 4 mm x
12 m.
Gear train:
The gear train converts the drill’s torque into a large winching force. The gear train design
makes it possible for the winch to be lighter and more compact.
Clutch knob:
The clutch knob allows the operator to manually disengage (unlock) the drum from the gear
train, enabling the drum to rotate freely (known as ”freespooling”). Engaging the clutch
”locks” the winch drum back onto the gear train.
Rope hook:
The rope hook is attached to the end of the winch rope. The rope hook is rated according to
the winch’s capacity. Hooks are usually used in combination with straps or chains.
Anchor hook:
The anchor hook is fastened to the anchor point. A strap will be connected to the hook and
then secured to a solid connection (anchor).
Fairlead:
The fairlead acts to guide the winch rope onto the drum.
WINCH MECHANICS
Before using your winch it is essential to understand how it works and the functions of the
key components.
Always know your winch. Take time to fully read the operation
manual in order to understand your winch and its operations.
Always read and understand your drill/driver operator’s manual
and instructions.
How the winch reacts to load
The winch is rated by winching capacity. The maximum winching torque occurs when there is
only one layer of winch rope on the drum. As the layers of winch rope on the drum increase,
the pulling power decreases. This is basics of mechanical advantage.
