The present disclosure describes a lift truck attachment system that includes a lift truck carriage with an upper carriage support and a lower carriage support secured between two support brackets. The lift truck carriage is dimensioned to fit at least partially between opposing masts of a lift truck, such that the upper and lower carriage supports do not extend substantially beyond a forward surface of the mast. A device assembly, is mounted to the lift truck carriage, the device assembly including a base portion removably secured to the upper and/or lower carriage supports via one or more attachments. The device assembly can include a carriage scale removably secured to the base portion, the carriage scale configured to support load handling fixtures, such as a lift fork. In some examples, a single carriage support is used.

According to various example embodiments, a pallet clamp apparatus for clamping a pallet to a pair of forks provided in a forklift includes a housing disposed adjacent to each of the pair of forks, a locking member, at least a portion of the locking member protruding to the outside of the housing to fix the pallet, a spring member configured to elastically press the locking member toward the inner side of the fork in a lateral direction, and a release member configured to release fixing of the locking member by pressing the spring member.

A base frame for a reach truck comprises a wheel arm subassembly comprising two wheel arms each having a front end and an opposing rear end. A load wheel receiver is positioned on each rear end and a counterweight is positioned at the front end of the wheel arms and coupled to the wheel arm subassembly by a plurality of screw connections. The plurality of screw connections comprise a first portion of screw connections and a second portion of screw connections. The first portion of screw connections each extend in a first direction and the second portion of the screw connections each extend in a second direction which is different from the first direction.

A lightweight, manually portable load carrying device with two wheels can raise and lower light to medium loads placed on its nose plate, using the torque of an electric motor. By this means, the traditional nose plate is used as a “lift plate,” and cargo can be raised or lowered to be placed in or taken out of motor vehicles, or onto and off of ledges, tables, counters or shelves, or any other elevated platform which would otherwise require manual lifting to reach.

A materials handling vehicle including a load handling assembly having a mast assembly, and a fork carriage assembly including a fork support and at least one fork assembly, the at least one fork assembly including a first fork member, which is fixed to the fork support, and a second fork member. The vehicle includes a tilt assembly that tilts the fork support relative to the mast assembly such that a central axis of the at least one fork assembly is positionable in a plurality of different positions relative to a horizontal direction. The vehicle includes a fork extension/retraction assembly that moves the second fork member relative to the first fork member in a first direction that is parallel to the central axis such that the fork extension/retraction assembly selectively moves the second fork member toward or away from the fork support in the first direction.

The present invention relates to a driverless transport device (10) for transporting objects (38), comprising a support structure (12) with an outer contour (14), a chassis (16) fastened to the support structure (12) having at least a first wheel (18) and a second wheel (20), wherein the first wheel (18) is rotatably mounted in the chassis (16) about a first axis of rotation (D1) and the second wheel (20) is rotatably mounted in the chassis (16) about a second axis of rotation (D2), a drive unit (22) with which the first wheel (18) and the second wheel (20) can be driven independently of each other, and an expanding unit (98) with at least one expanding arm (100), wherein expanding arms (100) are adjustable by means of an adjustment unit (106) between a first position, in which the expanding arms (100) are located within the outer contour (14), and a second position, in which the expanding arms (100) project at least partially beyond the outer contour (14). Furthermore, the invention relates to a driverless transport system (81), comprising a plurality of such driverless transport devices (10).
