Anchor, Tool, Shear Torque Limiter

A shear pin torque limiter is a mechanical device consisting of two shear halves mounted to a central pin such that the shear halves are free to rotate. Shear pins inserted into perimeter holes prevent the shear halves from rotating and are rated to shear at 500 ft-lb of torque per pin. Required torque can be achieved by loading the shear halves with the appropriate number of pins, i.e., 4000 ft-lb = 8 pins. The shear pin torque limiter is mounted in line with the torque motor and pile/anchor tooling.

• Measuring torque provides positive indication of anchor holding capacity in any soil type.
• The Torque Indicator mounts between the Kelly bar adapter and drive tool (or locking dog assembly).
• Includes twelve 1/2" plated grade 5 bolts and lock washers
