A transport machine is provided with a traveling device, a vehicle body, a vessel, a support device and a load detection device. At least a portion of the vehicle body is arranged above the traveling device. The vessel is provided on the vehicle body. The support device includes a slide mechanism that moves the vessel in a lateral direction with respect to the vehicle body, the lateral direction intersecting with a traveling direction of the traveling device when the transport machine travels straight. The load detection device detects a state of a load on the vessel. The slide mechanism is controlled based on a result of detection by the load detection device.

A mining shuttle car that trams on underground roadways includes a conveyor system and an operator's compartment adjacent to the conveyor system. The operator's compartment includes a rotatable seat and a control station. The operator's seat module is coupled to one or more joysticks that control the car, and the operator's seat module and the control station are mounted on a rotatable platform so as to be rotatable as a unit between a plurality of secured positions for operating the mining shuttle car. Forward movement of the joystick control relative to the seat steers the shuttle car about a point in front of the seat, and rearward movement of the joystick control relative to the seat steers the shuttle car about a point behind the seat. Forward and rearward movement of one of the joysticks steers the mining shuttle car in the same manner regardless of the rotational position of the rotational position of the seat.

A material extraction system is provided for an underground mine. The mine includes a roadway entry and a draw-bell entry intersecting the roadway entry and affording access to a draw-bell. The system generally includes a loader movable from the roadway entry into the draw-bell entry for removing material from the draw-bell, a sizer coupled to the loader for sizing the removed material, a material collector operable to collect the sized material, and a shuttle car operable to receive the collected material from the material collector. The material collector has a loading end and a discharge end, and material transport device extending therebetween. The shuttle car is movable along the roadway entry for transferring the collected material so as to facilitate a substantially continuous extraction of the material.

An entry conveyor including a conveyor pan formed by a plurality of pan sections that are hingeably connected to each other, at the two ends of which conveyor pan drive stations and/or return stations for a scraper chain are provided. Each pan section includes a top strand delimited by lateral profiles and the conveyor base and a bottom strand for the scraper chain as well as receiving elements for a pan section connecting mechanism, which elements are disposed outside of the lateral profiles. A pan strand including a plurality of pan sections that are disposed behind each other is provided in the conveyor pan, which sections are hingeably coupled via a center swivel bearing disposed on the center longitudinal axis of the conveyor pan or the pan sections. The invention also relates to the pan sections with the center swivel bearings.

A braking system for the control of vehicle speed, the vehicle including an engine having a first plurality of engine cylinders, an electronic throttle, electrical power source and engine brake adapted to provide engine braking, comprising an electronic control unit in communication with the engine electrical power source, engine throttle and engine brake, and a speed sensor adapted to measure the speed of the vehicle and communicate the measured vehicle speed to the electronic control unit, wherein when the measured vehicle speed is greater than a pre-determined vehicle speed threshold, the electronic control unit disables the engine throttle and applies the engine brake using a second plurality of the engine cylinders, the second plurality of engine cylinders being less than the first plurality of engine cylinders.
摘要:
A conveyor unit for a high wall mining system; a mining system employing a train of such units. The conveyor units are pushed in tandem into the mine. The system contemplates a motor mounted on a cutter at the head of the train; through a series of shafts and clutches, serially through the train of conveyor units, rotation power is transferred mechanically from the motor to turn the conveyor belts of the individual units. The invention includes a preferred coupling/clutch apparatus and a launch vehicle for adding conveyor units to the train which has the ability to start the rotation of the conveyor belt on the new unit as it is added.
