Abstract
Disclosed is a self propelled device and method for transporting and positioning bulk solids handling equipment across working surfaces of limited bearing strength. Multiple advancing sleds (10) and equipment base sleds (12) are connected by interlocking angles (21) and thrust cylinders (15). Alternate extension and retraction of thrust cylinders (15) cause alternate sleds to push forward while other sleds serve as anchors. Methods to use the self advancing mining sled in hydraulic mining and dry mining applications are disclosed.
Claims5
A device for relocating machinery across a working surface comprising:
- A. three or more sleds;
- B. linearly-acting positioning means consisting of at least one double acting fluid cylinder acting between said sleds for respective movement;
- and,
- C. control means to cause said positioning means to sequentially slide individual units of said sleds while using remaining units of said sleds as frictional anchors.
A method of relocating machinery across a working surface comprising:
- A. joining together three or more sleds provided with linear-acting positioning means for sliding said sleds with respect to each other;
- B. supporting said machinery on said sleds;
- C. sliding one of said sleds in the desired advance direction with said positioning means while using the remaining sleds as anchors;
- D. repeating said sliding of claim 4C for each of the remaining said sleds unit each sled has been moved in said desired advance direction;
- and,
- E. repeating said sliding of claim 4C and claim 4D until said machinery has been moved the desired amount.
