摘要： A wheel assembly includes a constant force mechanism and a wheel coupled to the constant force mechanism. The wheel is displaceable in at least one dimension, and the constant force mechanism imparts a substantially constant force on the wheel in the dimension. In one aspect, the wheel is displaceable in a first regime and a second regime. For a wheel displacement in the first regime, the constant force mechanism imparts a substantially constant force on the wheel, and for a wheel displacement in the second regime, the constant force mechanism imparts a variable force on the wheel. The variable force can be linear or non-linear to the magnitude of the displacement in the second regime and is equal to or greater than the substantially constant force.

摘要： A caster system wherein a constant force is applied to the caster for load support purposes. A plurality of casters are interconnected by a fluid conduit system and each caster includes an expansible chamber motor for adjusting the vertical position of the caster. A fluid pressurizing unit communicates with the conduits and an adjustable force compression spring selectively varies the biasing force on the piston to adjust the equal force imposed upon each caster wheel.

摘要： A load transporting apparatus is described including: a main body; a ground engaging wheel positioned at or towards one end of the main body and supported for rotation about a generally horizontal axis; a support member, which is connected to the main body, and which supports a pair of wheel assemblies, each assembly including a wheel which is supported for rotation about a generally horizontal wheel axis, wherein said wheel assembly permits the wheel to swivel about a swivel axis which is substantially perpendicular to the wheel axis and off-set therefrom; wherein the support member is connected to the main body by connection means which permits movement of the main body towards and away from the support member. Also described is an apparatus where the or a further connection means is configured to permit rotation of the support member relative to the main body about an axis which extends generally in a fore-aft direction of the apparatus.

摘要： A pallet jack power assembly upgrades a manually powered pallet jack to provide a motor-driven drive wheel. In one example, the manually powered pallet jack includes left and right steering wheels separated by a narrow distance. A frame of the pallet jack power assembly may be adapted for attachment to the pallet jack. The frame supports a drive axle, which in turn supports a drive wheel. Attachment of the frame of the pallet jack power assembly locates the drive wheel between the left and right steering wheels. The drive axle and a steering axle, supporting the left and right steering wheels of the pallet jack, may be located in a same vertical plane. A biasing device, such as a spring, may be used to provide a downward force on the drive wheel, thereby increasing friction between the drive wheel and the floor.

摘要： A straddle type material handling industrial truck providing an approximately constant force on the traction and braking wheel through pivotal mounting of the drive unit augmented by spring loading. The spring loading is accomplished by a spring mechanism which includes an upper spring bracket having a downwardly extending stop portion and mounted on the frame, a lower spring bracket having an upwardly extending stop portion and mounted on the drive unit, and a compression spring extending between the spring brackets, the stop portions being located within the compression springs and spaced apart a predetermined amount to limit the upward pivotal movement of the drive unit.

摘要： A lift truck includes systems and methods for improved stability control while turning, including a rotatable drive unit having a steerable drive tire. A first slide mechanism is coupled to the rotatable drive unit, and a second slide mechanism is mounted to a caster plate. A steering mechanism coupled to the rotatable drive unit is moved to steer the steerable drive tire, causing the first slide mechanism to interact with the second slide mechanism and to produce a downward pressure and/or reduce the downward pressure on a caster mounted to the caster plate.
