6V4085 Torque Multiplier Group Available{0614}

Usage:

The 6V4085 Torque Multiplier Group has a maximum input and output of 270 N·m (200 lb ft) and 1625 N·m (1200 lb ft) respectively, for a 6-to-1 power ratio with accuracy of ± 5%.

This tool has a 12.7 mm (.500") input shaft (socket) and a 19.05 mm (.750") output shaft with overload protection. The drive shaft will break when the output is 3% to 10% above the maximum output rating to prevent damage to the gears.

The tool has both clockwise and counterclockwise, 360° rotation, and it has a dial with 5° intervals for use when torque-turn specifications are used.

The 4kg (8.8 lb) torque multiplier group uses a tube-type reaction anchor.
