Self Recovery
Use of a Pulley Block or Snatch Block
Use of a Nylon Sling and Shackle
1. Always attempt to get the steel cable as straight as possible to the direction of the vehicle. It is acceptable to start a pull at an angle if it is
obvious that the vehicle will turn towards the hook anchoring point. Turning the steering wheel will assist the process. It is recommended
that the driver is in the vehicle.
2. Make sure hand brake and foot brake are free and that the transmission is in neutral.
3. When the driver’s attempt to regain vehicle traction is successful, he or she should be careful not to overrun the cable and risk the
possibility of it being trapped under the vehicle.
4. Do not move your vehicle in reverse to assist the winch. The combination of the winch and vehicle pulling together could overload the cable
and winch itself.
5. Do not connect steel cable or hook back to winch mount.
Vehicle self recovery using the pulley block attached to the anchor point for direct pull. In this instance the vehicle becomes the “load” and
the actual pulling power on the vehicle will be double at half winch steel cable speed. Do not connect steel cable or hook back to winch
mount.
A shackle should always be used when attaching winch hooks to nylon slings. NOTE: The shackle must pass through both eyes of the sling.
The safe working load of the nylon sling is based on the use of both eye ends. Do not use the cable or hook to connect directly to the nylon sling.
Direct pull on load using the winch vehicles as the anchor with pulley block attached to the load. The most important aid to successful
winching is the pulley block, which can be used to increase the pulling power of the winch of for indirect pulls. Pulley blocks can be used in
two modes. First mode is attached to the load and second is secured to an anchor point.
Indirect pull necessitated by obstructions or soft ground. Attach pulley block to load using a suitable anchor point. The angled direction taken
by the load and subsequent angle of steel cable feed back on the winch drum (extreme example shown). There may be unavoidable
circumstances requiring this mode, though in general it is not recommended unless applied in stages by moving the anchor point or vehicle
to avoid the sharp angled rewind on the winch drum. The actual load pulling power and steel cable speed will depreciate with any increased
angle between the steel cables. The anchor point, when used must be secure, using a tree, another vehicle or any firm structure to which a
pulley block can be used to your advantage.
