Abstract: Materials-handling vehicles, such as counterbalanced lift trucks, can incorporate a counterweight that includes a frame, a cavity, and a sensor-mounting recess. The counterweight may be configured to provide an unobstructed horizontal line of sight of at least 180 degrees for a sensor, such as an object-detection sensor, that is mounted within the sensor-mounting recess. A lift truck can include a lift assembly comprising a mast and a pair of forks, an operator compartment comprising truck steering and speed controls, a plurality of wheels, an energy source, a counterweight comprising a frame and a sensor-mounting recess, and a sensor.

Abstract: An accessory arm for a lift truck includes at least one rear attachment mechanism affixed to a rear overhead guard leg of the lift truck and a front attachment mechanism affixed to a front overhead guard leg of the lift truck. The accessory arm further includes an accessory bar rotationally mounted to the at least one rear attachment mechanism and to engage with the front attachment mechanism when the accessory bar is in a closed position. A wiring harness connected to a battery of the lift truck and routed within the accessory bar to a device mounted to the accessory bar, the wiring harness to provide power to the device.

Abstract: A hybrid wheel hub for trucks is configured to accept interchangeably a threaded screw-on hubcap or a bolt-on hubcap. The hybrid wheel hub comprises a barrel with an axial bore for receiving an axle along a longitudinal axis of the axial bore and a radial flange for attaching a wheel, the barrel having an inboard end and an outboard end including an outboard bearing cup for retaining an outboard bearing assembly within an inner surface of the axial bore. An annular perimeter of the outboard end includes a plurality of bolt holes positioned to receive cap bolts to retain a bolt-on hub cap over the outboard end. A threaded track protrudes radially inward towards the longitudinal axis of the axial bore and is internally threaded circumferentially around the longitudinal axis in position longitudinally to receive a screw-on hub cap having external threads.

Abstract: A wheel hub includes a barrel, a flange extending radially away from the barrel and a connection member connecting the flange to the barrel. The barrel includes an outboard bearing bore and an inboard bearing bore. The flange at least partially overlaps the inboard bearing bore along a radial direction perpendicular to a longitudinal axis of the barrel. The connection member includes an outboard side facing toward the outboard bearing bore and defining outboard ribs and outboard recesses alternately disposed around the circumference of the barrel. Each outboard recess is interposed between the flange and the barrel along the radial direction perpendicular to the longitudinal axis of the barrel.

Abstract: A hub and drum assembly includes a recess around one or more stud holes in the drum and a shipping nut threaded onto a stud and contained in the recess. The recessed shipping nut securely fastens the hub to the drum during shipping. At a destination facility, the shipping nut does not have to be removed before wheels are installed on the huh and drum assembly. A method of assembling a portion of a drive train including a hub and drum assembly with a recessed shipping nut is also provided.

Abstract: An improved brake drum and method for machining and balancing a brake drum are provided. The inner facing surface and the outer facing surface of the brake drum are machined. The inner and outer faces of the hub end of the brake drum are also machined. The machining is accomplished in a single operation that results in a radially balanced brake drum.

Abstract: Brake drums are described with a stacking structure which allows the brake drums to be stacked directly on top of one another. Desirably, some nesting of the brake drums occurs during this stacking. A method of stacking brake drums for storage and shipment is also described.

Abstract: An improved brake drum and method for balancing a brake drum are provided. A section of the raised squealer band of the brake drum is removed to correct the imbalance. Preferably, a cutting machine is used to make a continually varying depth cut along a section of the squealer band to correct the imbalance.
