Lock-N-Lift tools are the original patented dovetail-style lifting tools and are the industry benchmark for safe and easy handling of road plates. Since 1981, Lock-N-Lift tools have been put to use throughout North America eliminating the need for pry bars, installation tools or thread cleaning when moving and storing road plates.
Lock-N-Lift maximizes worker safety by eliminating the need to ever put a hand, foot or any tooling under a road plate, even during the installation of the weld-in plate. Made in the USA from the best available aircraft quality AISI 4330 steel. The tools are heat treated to provide a safe working load of 8,000 pounds with a 5:1 safety factor.

Shop Lock-N-Lift
Road work crews around the country use a road plate lifting device made from steel to cover road sections under construction. In Washington state, we at Greenshields Industrial Supply offer the Lock-N-Lift products essential to lifting and placing metal road plates.
It offers welded lifting assemblies that combine to form an easy-to-use steel plate lifting device. At Greenshields Industrial Supply company, we offer the Lock-N-Lift Model #750 or Model #800 for road plates.
WHAT IS LOCK-N-LIFT?
It is a type of steel plate lifting equipment featuring a flush-welded receiver attached to the road plate with a lifting tool that locks the place onto the receiver plate. The lifting tool then connects to a shackle or hook and is ready to lift and place.
A single receiver and lifting tool rate safely up to 8,000 pounds weight. For plates that weigh over 8,000 pounds, use two receivers and two lifting tools evenly spaced around the center of your road plate for even weight distribution.
Its system offers two model options. The Model #750 was the original design introduced in 1981 and requires a chain or anchor shackle attachment for lifting. The Model #800 added the convenience of lifting by a hook or chain shackle in 1988.
Both models allow workers to lift road plates without ever having to place tools, hands, or feet under a steel construction plate.

WHAT ARE ROAD PLATE LIFTING DEVICES USED FOR?
Workers can use this road plate lifting device to perform straight lifts of heavy steel plates safely. The manufacturer warns against the following uses when using Lock-N-Lift steel plate lifting material:
● DO NOT DRAG, PUSH, OR PULL. Lock-N-Lift tools are for straight vertical lifting only. Pushing, pulling, or dragging can cause foot break, ankle weakness, or pinching of the center weld-in plate.
● Use the appropriate tools. Model #750 should only attach to a chain or anchor shackle. You may use a hook or chain shackle with the Model #800 only, and never an anchor shackle.
● Do not use a single of this device system for an extra-long plate. Measure the plate into thirds and attach two of these devices at each third. Use a spreader bar for added stability.
● Use a hook or shackle rated for a minimum of 4 tons. For either model, lock n lift, ensure the minimum working load limit is at least 4 tons.
