ANCHORING EQUIPMENT - LOCKING DOG ASSEMBLY

Description:
Slingco’s 10k Drive Wrench Assembly is a tool system for the installation of screw anchors.
Designed to connect the square anchor of a drive motor or screw anchor to the hexagonal Kelly Bar of a bucket truck. System options include Drive Wrenches to suit different
sized anchor rods; a Drive Wrench lock; two Kelly Bar Adapters to fit the hex drive bar’s dimensions (2.5 in and 2.625 in) and one Square Head Kelly Bar Adapter to suit
3 in Square Drive Bar.
The Drive Wrench Lock attaches to the Kelly Bar Adapter and makes the installation of the Anchor Rod much easier. The three position rings of the lock assembly ensure easy capture of the Drive Wrench and Anchor Rod, holding them securely while under torque and releasing them when needed.
The Drive Wrenches are designed to allow Anchor Rods to telescope inside, and secure to, the Drive Wrench Lock. The Drive Wrench transfers the torque from the Drive motor to the Screw Anchor, and are rated to 10,000 ft-lb.
