The Pro Torque Tools TM-55W Planetary Gear Torque Multiplier offers a torque ratio of 19.7:1 and a maximum output of 4,038 Ft Lbs or 5,500 Nm with a 40 degree reaction arm.

Anywhere there's a high torque, confined space situation, a torque multiplier should be close at hand.

Not only will a planetary gear torque multiplier help make sure your fasteners are properly tightened, but it will help improve worker efficiency - two things which add up to an increase in productivity.

Through a relatively simple arrangement of gears a torque multiplier makes the toughest nut-turning jobs a snap.

Generally, a torque multiplier is needed when a prescribed amount of torque must be applied to threaded fasteners having a diameter of one inch or more, and/or when fasteners must be accurately tightened in a work space which precludes the use of a torque wrench with a long arm length.

Gear Ratios on torque multipliers can have up to a 10% +/- variance due to the friction within the gears that generate the output force. They will be most accurate when used between 50-75% of their max output. Torque levels at the high end of the range will suffer from friction loss and have a reduction in the actual output ratio. For frequently used multipliers, you should choose a model that has a max range that is at least 25% above your intended max output.
