  • Patent number: 4828450
    Abstract: A load handling attachment for a forklift truck has an upright base, a load engaging platen, and a push-pull assembly connected to the base above the platen. The attachment also includes a device for connecting the base frame to a carriage of the forklift truck to resist forward movement of the base relative to the carriage. The connecting device includes a linearly movable device mounted on a side frame member of the base, the linearly movable device engaging an upright fork portion when in a carriage attaching position.

  • Patent number: 4611962
    Abstract: A container chassis bundling system uses permanently affixed clamps 14, 14a, 40, 42, 42a, or 42b, for example, placed on a container chassis 10 to interconnect container chassis into an integral stack of chassis. Usually, chassis are interconnected with corresponding twist-lock bayonets 18 and twist-lock receivers 12 between corresponding top surfaces of the chassis and either rail 42, 42a, or 42b or landing gear interconnections 14 or 14a between the rails on the bottom flanges of the other chassis. An axle clamp 40 may connect the axle of one chassis to the kingpin of another chassis. Rail clamps 42, 42a, or 42b may also be used to connect corresponding top surfaces.

  • Patent number: 4600350
    Abstract: A container chassis handling attachment for a lift truck having a lift carriage includes a frame for attachment to the lift carriage. It also includes a pair of upper and lower laterally-spaced forks independently mounted to the frame by separate four-bar linkages and movable by separate hydraulic cylinders. A clamp-positioning means cooperates with the forks to rotate the forks and any chassis gripped thereby through 180.degree.. The attachment is used to store a chassis by clamping from one side opposing top and bottom surfaces of the chassis, lifting the chassis, rotating the chassis about 90.degree. to a substantially upright position, and depositing the chassis in such position against a support. Alternatively, the chassis may be rotated 180.degree. to an upside-down position and deposited onto an underlying right-side-up chassis, eventually to form a stack of alternating right-side-up, upside-down chassis.

  • Patent number: 4493421
    Abstract: A side-loading rack for storing wheeled container chassis in a nearly vertical, slightly leaning position has a framework of dividers defining plural vertical slots open on one or both sides for receiving a container chassis sideways in each slot. Each divider includes a chassis support arm which extends front to rear along an upper side of each slot. A wheel support on one side of each divider is positioned in a lower part of each slot to support the wheels of a container chassis so that the chassis frame leans at a small angle from vertical against the chassis support arm of an adjacent divider. Corner castings are positioned at opposite ends of the rack so that it can be handled in the same manner as a container. The dividers of one embodiment are constructed with an upper portion, including the chassis support arms, either removable from or collapsible into the lower portion of the frame means to form a more compact structure for ease of handling.

  • Patent number: 4427117

Each divider includes a chassis support arm which extends front to rear along an upper side of each slot. Wheel supports are mounted on the dividers in a lower part of each slot so that the wheels of a container chassis stored in the slot rest on the wheel support and against one divider and the chassis frame leans at a small angle from vertical against the chassis support arm of an adjacent divider. Corner castings are positioned at opposite ends of the rack so that it can be handled in the same manner as a container. The dividers are constructed with an upper portion, including the chassis support arms, either removable from or collapsible into the lower portion of the frame means to form a more compact structure for ease of handling.
