Snatch Block
An important aid to successful winching is the use of snatch block,
which can be used to increase the pulling power of a winch or change
the direction of a pull.
A winch double lined with a snatch block creates a mechanical
leverage cutting the effort required by nearly half.
The double line pull shows self recovery using a snatch block
attached to an anchor point; the pull applied to the vehicle is almost
twice as much as the line pull of the winch.
The use of one snatch block shows an indirect pull where the
vehicle is limited due to unsuitable ground or obstruction. The pull on
the load is the actual line pull of the winch.
If more than one snatch block is used, they must be located at
least 100 cm (40″) apart.
Mounting
1). Use the mounting hardware (M10 bolt, nut and washer) to mount the winch on a flat
surface (fig 5).
2).The motor, drum and gear housing must be properly aligned (fig 6).
IV. Installation
Before using the winch, make sure all electrical parts have no corrosion or damage; relative
environment should be clear and dry.
The voltage drop from the point of supply to the load of machine must not exceed 10% of the
nominal voltage under normal operating condition.
