Model #750 Working Requirements
* * * STRAIGHT LIFT USE ONLY * * *
Lock-N-Lift Tools are 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 trench plate, stress will develop on the ankle part of the tool causing foot breakage 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.
The Model 750 Tool is designed to be used with a shackle only and must be inserted into a Lock-N-Lift #500B weld plate. It may be used with a chain or anchor shackle.
For extra long plates, it is recommended that two tools be used with a spreader bar for stability and to minimize stress. The plate should be measured in thirds along its longest part and a #500B weld in plate placed on each third division.
The Model 750 tool works well with either anchor or chain shackles with either 7/8” or 1” diameter pins. The shackles should have a working load limit of 4 tons minimum.
