Abstract: An excavator (1) includes an excavator main body (7), an apron (2) for the receipt of excavated material and a conveyor (3), the apron being located at or in proximity to the front of the main body, the conveyor extending from the apron to the rear of the main body. In use, the conveyor moves excavated material from the front to the rear of the main body, the excavator further includes an arm (11) having an attachment (5) for excavating material and moving the excavating material towards the apron (2). The excavator has a support associated with the front of the main body, the support being movable from a first position in which the support is in resilient contact with the ground to a second position in which there is substantially no contact between the support and the ground. The support includes one or both of the apron and conveyor.

Abstract: A liquid treatment apparatus treating a surface of a substrate held generally horizontally on a stage in a housing by supplying a treating liquid to said surface from a supply nozzle. The liquid treatment apparatus includes a cup body provided so as to surround the substrate held in the substrate holding part laterally, the cup body being mounted detachably to a base inside the housing from an upward direction thereof; a cup body holding part holding the cup body detachably; and an elevating mechanism moving the cup body holding part up and down between a first position at which the cup body is mounted upon the base body and a second position located above the first position.

Abstract: A tunnel digging apparatus has an undercarriage pivotally attached to a moving means, the undercarriage being pivotable between a first moving position where the machine may be moved over a surface by operation of the moving means and a second operating position such that at least a portion of the undercarriage is in contact with the surface. The machine in the operating position is supported by at least a portion of the moving means and the portion of the undercarriage in contact with the surface.

Abstract: In the particular embodiments of the invention described herein there is disclosed apparatus for loading particulate material into a train of coupled rail cars. The apparatus includes open topped rail cars which carry a continuous rail track of rails which are attached to the upper edges of the cars, a loading car which carries a ramp which leads from a low level to the track on the rail cars, a bucket loader and perhaps a conveyor for loading a self propelled load distribution vehicle which is adapted to run under its own power on the ramp and the track.

Abstract: An apparatus for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial horizontal axis shared by the forward section of a first conveyor, fluidizes a muck pile to continuously load material onto the first conveyor. Actuators for independently oscillating the penetrator and independently positioning the first conveyor are provided. An optional second conveyor may be employed to transport the material away from the first conveyor.

Abstract: A continuing mining machine wherein a crusher is placed inboard of the machine and has a dipper machanism as well as a loading chute. The dipper is of a twin handle type so that it can straddle a feeder chute thus affording a wide area for excavating. The placement of the crusher in a central location within the machine allows for stability and obviates the need for swivelling of the crusher during operation of the machine.

Abstract: An apparatus and method for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial axis shared by the forward section of an endless conveyor, fluidizes a muck pile to continuously load material onto the conveyor. The conveyor, hinged approximately amidships, is mounted above a movable frame. Actuators for independently oscillating the penetrator is provided.

Abstract: Apparatus for removing and conveying a heap of debris includes a continuous conveyor supported by a frame and having a charging end and a discharging end; two cantilever arms having outer free ends and having inner ends pivotally supported on the frame for swinging movement about a horizontal transverse arm pivot axis between lowered and raised positions; a transverse crossbeam extending between the outer free ends of the arms and pivoted thereto for swinging movement about a horizontal beam axis; a loading shovel having an open front for shoveling up debris and a back wall which has an upper edge, the shovel being pivoted to the crossbeam for swinging movement about a horizontal shovel pivot axis which is located near the upper edge of the back wall, the arrangement of shovel, crossbeam and arms being such that in the lowered position of the arms, the shovel pivot axis is above the beam pivot axis and the shovel is swingable to a lowered, loading position in engagement with the beam for shoveling in debris a

Abstract: In one exemplar embodiment, an apparatus for handling and conveying materials is disclosed having a movable chassis, a longitudinally extendable conveyor assembly mounted on the chassis, the conveyor having a projecting loading end capable of limited longitudinal and arcuate vertical movement to a position immediately adjacent the location of the material being handled. An articulated boom assembly is rotatably mounted on the chassis with the movable free end carrying a pushing and pulling blade for loading the material unto the loading end of the conveyor.

Abstract: Heavy breaking giant excavator having a mining system with the following components: a boom having a feed chute and conveyor equipment at one end thereof; and sifting, crushing, and transfer equipment at the other end thereof, and a dipper boom arrangement is disposed on the end of the vertically supported, swivellable boom onto which mined material is fed. The dipper boom has a limited hydraulic capacity dipper disposed thereon.
