Abstract: The present invention discloses a method and apparatus for excavating material from a mining or reclamation operation, and is generally considered useful in open cast mining operations. The apparatus has a first conveyor and a second conveyor attached to a chassis. The first conveyor is fitted with a material remover such as a excavator bucket on a first end. Material discharges from the first conveyor onto a second conveyor which is generally longitudinally aligned with the first conveyor and has a material receiving point located elevationally below the discharge point of the first conveyor.

Abstract: A method and apparatus for cleaning beaches or other similar sandy areas which includes a digger chain and an associated sweeper chain for capturing debris and other articles and conveying the same to a collection box or separation conveyor.

Abstract: An earth mover includes a fixed scraper blade and a moveable floor section. The moveable floor section can be pulled rearwardly to provide an opening between the fixed scraper blade and the forward edge of the floor section. The floor section is mounted on tracks which run on the exterior of the sidewalls of the bowl. The forward portion of the tracks are angled upwardly which keeps the floor tight against the bottom of the bowl. When the floor is in the open position, it allows the floor to extend downwardly below the thick scraper blade. This allows the forward edge or blade of the floor section to act as a leveler as the dirt is being unloaded from the earth mover.

Abstract: An earth mover scraper combination having chain driven elevator drive sprockets for each of two chains which are mounted on plates that include pins extending into the frame of the elevator support. Two jacks are likewise inserted into the frame of the elevator support and can be used to force the pins away from the frame support thereby forcing the sprocket away from the frame support and tensioning the chain. Preferably, the jack is a hydraulic jack that can be operated with a simple grease gun. Metal shims are then placed between the mounting bracket and the frame assembly to maintain the chain tension.
