The Atlas Heavy Duty Pulley Block is designed for use with our 16,800 lb. Atlas recovery winch. The Atlas pulley block is designed to increase the pulling capacity of your Atlas winch. The Atlas pulley block can be used to change the pulling direction of the winch wire rope without damage to the wire rope. When used correctly, the Atlas pulley block will help to lower the amp draw of your winch motor because the motor is doing “less work”. When the motor draws lower amps it also operates at a lower temperature which helps to extend the life of the motor. When you use the correct winch accessories, your Atlas winch can do “more work” with less effort.
