TMT Class 4 - 5 Multiplier

TMT Class 4 - 5 Multiplier

Torque Tool
The TMT Class 4 - 5 Multiplier enables the use of a Class 4 torque tool in a Class 5 receptacle. It incorporates a gearbox to provide a torque multiplication at the output.
A Class 5 Multiplier is simpler, lighter and a more cost effective solution than a hydraulically actuated Class 5 torque tool, when coupled with a Smart Torque Tool MK2, it provides greater accuracy, control and safety than hydraulic tools that utilise relief valves for over-torque protection.
The Class 4 receptacle retains the latching flange which provides the ability to engage and disengage the class 4 torque tool at will, this also means the class 5 tool can be mounted to the class 4 heavy duty FLOT.
The Class 4 to 5 Multiplier has a design limit of 8500Nm, which exceeds the Class 5 limit of 6779Nm.
