  • Patent number: 8272151
    Abstract: Equipment for mining and excavating includes a bucket used to remove overburden, a boom for positioning the bucket, and a hoist and drag cable for controlling the bucket. The equipment also includes a drum; a pedestal, a pinion assembly, and a cartridge assembly. The drum is used to wind the hoist cable or the drag cable. The pedestal supports the drum and surrounds a bull gear attached to the drum. A pinion of the pinion assembly extends within a port in the pedestal to engage the bull gear. The cartridge assembly is attached to the pedestal and includes an electric motor having a shaft extending from the motor, and a gear reduction coupled to the motor shaft. The pinion assembly is driven by the motor via the gear reduction. The pedestal allows the pinion assembly and other components to be removed or installed, without entirely separating the cartridge assembly from the pedestal.
