Abstract

There is shown a skidding assembly having a pair of rail platforms. Each rail platform has a base member and a pair of boxed members spaced to form a gap there between. A pair of sawtooth racks are positioned adjacent the inside portions of the side boxed members. A pair of skid shoes are mounted over the upper walls of the boxed members and is configured to connect to a hydraulic cylinder system positioned in the gap between the boxed members. The hydraulic cylinder system includes movable cams that are able to adjust orientation to control the direction of travel of the skid shoes.

Dependent claims

A skidding assembly comprising, a pair of rail platforms, each rail platform includes:

a base member;
a pair of side boxed members separately positioned on either side of the base member to form a gap there between, each side boxed member including at least an upper wall structure and an inner wall structure;
a pair of sawtooth racks separately positioned adjacent each of the inner wall structures of the pair of side boxed members;
a pair of skid shoes, each skid shoe having a top plate configured to rest over the upper walls of the pair of side boxed members and further having a pair of braces positioned between the sawtooth racks and secured to the top plate, each of the braces includes a notch;
a hydraulic cylinder system positioned between the sawtooth rack and having a piston arm secured to a pin, the pin being positioned in the notches on one of the pair of skid shoes, which attaches the hydraulic cylinder system to a skid shoe;
and
a pair of cams separately mounted to a side of a base of the hydraulic cylinder system, each cam movably secured to the base and the pair of cams having a first orientation configured to cause the hydraulic cylinder system to move the skid shoe in a first direction and further having a second orientation configured to cause the hydraulic cylinder system to move the skid shoe in a second direction.
