摘要： A drill bit carousel for use on a blast hole drill includes a base structure that movably supports a plurality of drill receptacles. The drill bit carousel is movable between a storage position and at least one exchange position. In the exchange position, one of the drill receptacles is aligned with a centerline of a drill pipe string. In the storage position, the drill bit carousel is clear of the centerline of the drill pipe string.

摘要： A mining shovel (10) includes a hydraulic system comprising a plurality of fixed displacement pumps (104,106,108,110) driven by a variable speed motor (100), and a tank (68) system comprising an upper return tank and a lower supply tank (70). A cylinder manifold (64) is connected to the pump control manifold (112), and includes a directional control valve for directing the extend and retract functions of the cylinder (50), while accepting fluid flow in a single direction from the pump control manifold. The single direction flow allows for the use of smaller fluid conduits (61), such that the hose providing a high pressure supply can be comparatively smaller than the return hose (67).

摘要： A semi-closed hydraulic system for use with heavy equipment includes a double-acting cylinder, a reservoir, first and second electric motors, first and second electric pumps, a pressure sensor, and a controller. The double-acting cylinder has a rod end and a cap end, and the reservoir is designed to provide hydraulic fluid to and receive hydraulic fluid from the cap end of the double-acting cylinder. The first pump is connected to and designed to be driven by the first electric motor. Furthermore, the first pump is bi-directional and is intermediate to the rod end and the cap end of the double-acting cylinder, such that the first pump is designed to provide hydraulic fluid to the rod end from the cap end, and to the cap end from the rod end. In addition, the second pump is coupled to and designed to be driven by the second electric motor, where the second pump is intermediate to the cap end of the double-acting cylinder and the reservoir. The second pump is also bi-directional and designed to provide hydraulic fluid to the cap end from the reservoir, and to the reservoir from the cap end. The pressure sensor provides an output signal related to the pressure of hydraulic fluid of the rod end of the double-acting cylinder, and the controller is connected to the pressure sensor. The controller operates the first pump at least partially as a function of the output signal provided by the pressure sensor during operation of the semi-closed hydraulic system.

摘要： Equipment having an energy management system includes an articulated arm, a work implement, an energy management system, and a hydraulic circuit. The articulated arm includes hydraulic actuators designed to maneuver the articulated arm, and the work implement is fastened to the articulated arm. The energy management system is adjustable between a first configuration and a second configuration, and includes a hydraulic rotating machine and an electric rotating machine coupled to the hydraulic rotating machine. When the energy management system is in the first configuration, the hydraulic rotating machine and the electric rotating machine function as an electric motor powering a hydraulic pump. When the energy management system is in the second configuration, the hydraulic rotating machine and the electric rotating machine function as a hydraulic motor powering an electric generator. The hydraulic circuit is designed to supply a hydraulic fluid to drive the hydraulic actuators when the energy management system is in the first configuration, and is further designed to recover the hydraulic fluid from the hydraulic actuators and to generate electrical power when the energy management system is in the second configuration.

摘要： A crowd control mechanism for a power shovel includes an extendible dipper handle having an extended position and a retracted position. A double acting hydraulic cylinder having a an extendible ram has one of the cylinder and the ram fixed to the dipper handle and the other of the cylinder and the ram is stationary relative to the dipper handle. At least one of the cylinder and the ram have at least one of a blind end port and a rod end port, and at least one of the cylinder and the ram have the other of the blind end port and the rod end port, wherein hydraulic fluid flowing into the cylinder through the blind end port urges the ram toward an extended position to extend the dipper handle, and hydraulic fluid flowing into the rod end port urges the ram toward a retracted position to retract the dipper handle. Hydraulic fluid flowing into and out of the cylinder is controlled by one or more pilot operated poppet valves. A spool valve is disposed in a pilot line controlling at least one of the pilot operated poppet valves, and the spool valve controls the flow of fluid into the pilot line to control the at least one pilot operated poppet valve as opposed to a spool valve directly controlling the flow of hydraulic fluid into and out of the cylinder.

摘要： A dragline excavating machine includes a gearless direct drive AC drive motor for driving each of the hoist and the drag drums in the system. The gearless AC motor is driven using a digital system which receives AC power from the utility system rectifies the power using active front end circuits, and converts the resultant DC to a frequency controlled AC using an inverter circuit. The resultant AC signal is employed to drive the gearless AC motor, resulting in reduced harmonic distortion, unity or leading power factor, and increased efficiency, reduced operating costs, and reduced mean time between failure.

摘要： A blast hole drill with a drill head mounted on a mast has a pipe carousel on the drill deck which holds drill pipe along the length of the deck. A pipe handling arm mechanism has a lower arm portion pivotally mounted on the deck and an upper arm portion pivotally mounted to the lower arm portion. The upper arm portion has jaws that grasp a drill pipe. A ram connected to the upper arm portion pivots the arm mechanism until the lower arm portion engages a stop adjacent the mast. The ram thereafter continues to pivot the upper arm portion until a drill pipe carried thereby is aligned on the mast.

摘要： A method, system, and apparatus for providing energy discharge capability for a junction box that includes at least one ultra- or super-capacitor. A discharge resistor is connected to a first terminal block of the junction box. A normally-open relay is connected to a second terminal block of the junction block, the relay being connected in series between the discharge resistor and the second terminal block. The normally-open relay is closed to create a discharge path for discharging energy stored in the at least one ultra- or super-capacitor. The junction box is capable of being safely serviced after the energy stored in the at least one ultra- or super-capacitor has been discharged by way of the discharge path.
