• Portable

There is no fixed link to a vehicle; therefore you can take the winch anywhere. Tether it to any solid object: a tree, a post, a rock or even to the ball hitch of your vehicle.

• Powerful - Up to 2000 kg (4400 lb) of pulling power

The Portable Winch^TM will pull 1000 kg (2200 lb) single line. If you need to pull extremely heavy loads, we offer a snatch block kit including a swing-side pulley and locking steel carabiner. The pulley is attached to the load with the carabiner, and the rope is attached to the winch anchor. This lightweight system effectively doubles the pulling power of the winch to an amazing 2000 kg (4400 lb) pulling capacity!

• Lightweight - Weighs only 16 kg (35 lb)

Both winches have differing merits, the second example is most likely to be the one our group will use during our calculations as it is portable, and could be carried by hand, it will not add significantly to our overall payload, and could be modified to enable it to take a greater weight.
