Why Use Spartan’s Multi Stage Hydraulic Bolt Tensioner

Below is the interactive Three Dimensional Model and the advantageous features that Spartan’s Hex Type SET series Low Profile / Ratchet Type hydraulic torque wrenches provide.

OVER STROKE ALARMING MARK

The End cap is designed to bear high back pressure. This allows the piston operation to be smooth and the forward force is applied properly. A red marked line denotes an over-stroke, warning the user to stop the hydraulic pressure.

SPRING-LOADED NUT ENGAGEMENT

The spring-loaded nut runner automatically engages the nut once the profile matches.

AUTO RETRACT PISTON

The automatically retracting piston allows for a quicker operation.

GEAR DRIVE

The gear drive provides a mechanical advantage, while using a manual torque wrench to rotate the nut.
