Heavy duty trench plate lifting made safer

This movie requires Flash Player 9

Welcome to Lock-N-Lift LLC, the inventor and world’s foremost expert for dovetail style steel plate lifting tools.  Our tools make your job of lifting and handling heavy steel trench and road plates safer and easier. Lock-N-Lift’s revolutionary design was first patented in 1981 and has become an industry standard and our specialty.  The dovetail design gives our heavy-duty hoisting tools the Lock-N-Lift Advantage of safety, ease of use and reliability.

The Lock-N-Lift system consists of a receiver (#500B) and a lifting tool (#750 or #800). The receiver is flush welded into the center of each steel trench plate.  The lifting tool is inserted into the receiver plate and locked into place.  A hook or shackle is attached and your plate is ready to lift.  There are no threads to maintain, no need to reach under a plate, just easy, balanced, controlled lifting.  The flush mounted receiver eliminates trip hazards and the need for storage dunnage.

With single point lifting, our lifting tools are rated for 8000 pounds with a 5:1 Safety Margin.  Plates that weigh more than 8000lbs can be lifted with two weld plates and two tools.

We also sell tools with complete chain assemblies.

Our tool was conceived in the field by inventor Fred Silva, with the objective of making a dangerous job safe. With over 30 years of experience making industry-leading lifting tools, Lock-N-Lift, LLC is committed to making YOUR job site safe.

Trust Lock-n-Lift tools for all of your trench and road plate handling needs.
