ABSTRACT:
A device is disclosed for realignment of sidewalk sections displaced by settling or root lifting, where a hazardous step exists at a joint or crack. It comprises a rigid longitudinal span supported over the section, with cross members reaching over the section sides. Hooks are suspended from the ends of the cross members, and hooked under the section sides. Winches on the cross members raise the hooks, lifting the section. Dirt is added under the section and graded with a long-handled spreader to realign the section effectively and inexpensively.
This method of repair is much better than repouring or patching. Repouring is expensive, and makes the adjacent sections look old by comparison. Patching produces a short ramp, which is itself a hazard and has a makeshift appearance.
The device is light enough to be manually positioned with attached wheels, stable in operation, and inexpensive. The only repair material used is dirt, making repairs very inexpensive.
