The KEY●LOK LIFTING SYSTEM is designed to provide a safe, watertight and economical means of handling precast concrete structures.

The polypropylene lift pin insert is installed during the manufacturing process and becomes an integral part of the structure with a predetermined thickness of concrete forming a barrier to prevent infiltration into the structure.

The lift pin and lift bar hardware is designed to provide a safe and durable means of handling precast concrete structures.


 

KEY ADVANTAGES
The KEY●LOK LIFT INSERT is designed with a key slot to prevent rotation in the mold and to provide easy form removal in both wet cast and dry cast methods of production.

The insert forms a precise cavity to accept the keyed lifting pins. This assures minimum movement of the lifting device during handling.

The shape of the insert locks the lifting device into the cavity.   As lifting tension is applied the KEY●LOK Lift Pins rotate 90° to securely lock in place in the KEY●LOK Lift Insert.

The KEY●LOK Lift Pin Insert eliminates the necessity of a cold joint in patching the lift hole allowing immediate backfilling of the structure, enhancing project quality and safety.

The use of an A●LOK Manhole Lift Bar assures that the Lift Pins stay perpendicular to the manhole wall while lifting.
