ROAD PLATE LIFTER

PIT LIFTER
PUSH TROLLEY

The Road Plate Lifter’s groundbreaking design, first patented in 1981, has become an industry standard for lifting steel road plates around the world.

Its unique dovetail design provides enhanced safety, ease of use, and reliability compared to other lifting systems. The Road Plate System includes a receiver plate and a lifting tool. The receiver is flush-welded into the center of each steel trench plate, eliminating trip hazards and allowing plates to be stacked for efficient storage.

To lift, the tool is inserted and locked into the receiver plate. A hook connects directly through the elongated hole of the lifter, with no need for an additional shackle. This allows for quick, simple, and safe operation.

Because the lifter connects directly into the plate and contains no threaded parts, routine maintenance is minimized, offering a durable and low-maintenance solution.

WORKING REQUIREMENTS
Road Plate Lifters are designed to be used straight up and down (in the vertical line) and, not to be used for side pull or push. If the tools are dragged or pushed to the side or along the ground while in a steel plate stress will develop on the bottom “dove tail” part of the lifter, leading to or causing it to crack or break and/or the center plate to become pinched. If a tool is abused in this fashion, tool life will be shortened and the working load limit for the tool will be unknown.

LARGE PLATES
For extra-long plates, it is recommended that two tools be used with a spreader bar for stability and to minimise stress. The plate should be measured in thirds along its longest part and a weld in plate placed on each third division. In some cases for stiffer road plates two plates have been installed next to each other.

WELD IN PLATE
The weld in plate contains the female connector for the lifting tool and is easily welded into items that are being lifted and/or lowered. When properly installed, the weld-in plate sits flush to the surface of the item it is welded into, eliminating any
trip hazard. The plate is designed for easy welding into road plates made of Grade A36, A50 or A992 steel. It takes approximately 20 minutes to install the weld-in plate in the centre of a 25mm thick road plate. Manufacturers’ recommendation that plates should be load tested after welding in of the plate. Rangers’ technical service representatives can come out to site once the plate has been welded in and can proof load test each plate.

HOLE SIZE
Cut a 116mm x 116mm hole in the desired location of the steel road plate. Hole must be 3mm larger than the weld in receiver plate or it could buckle from expansion during welding process.

MAINTENANCE AND INSPECTION
The plate requires no added routine maintenance but should be inspected (and tested if needed) at a minimum of yearly intervals as per Australian standards recommendation by a competent person (see Australian standard for competent person definition).
