Lift trucks designed with a common chassis can include an ergonomically improved operator compartment, wheels, lift assembly, power plant, energy source, steering, seat, and counterweight components. Modular chassis designs can accommodate different form factors and different energy sources to accommodate different end uses of the lift truck, including lift trucks having a low floor, seatside steering, and/or a combination of operator-inaccessible compartments for high-reliability components and operator-accessible components for components that may require more frequent or convenient access. In one embodiment, the energy source is a lithium-ion battery bank in an operator-inaccessible compartment under a low, broad floor that facilitates easy entry into and exit from the operator compartment as well as ergonomic operation by the operator.

A battery power supply (1) for an industrial truck (8) used in a potentially explosive area is provided, having a housing (2) having a housing body (47) and a lid (4), wherein the housing body (47) has a receiving chamber (48) for receiving a battery tray (3) that has an inner chamber (20) having a traction battery (25) arranged therein, and the lid (4) is releasably placed on the housing body (47) using securing means (53), and the battery tray (3) has a battery tray lid (49) and a base (26) having walls (17, 18) extending away from the base (26), wherein, in a region adjacent to the base (26), at least one wall (17, 18) has a recess (19) penetrating the wall (17, 18) into the inner chamber (20).

A floor suspension system for a material handling vehicle is provided. The floor suspension system includes one or more coupling assemblies to couple a battery compartment and an operator compartment of the material handling vehicle to a fork frame of the material handling vehicle. The one or more coupling assemblies each include a first pivot arm to pivotally couple the battery compartment to the fork frame, a second pivot arm to pivotally couple the operator compartment to the fork frame, and a coupling arm to couple the first pivot arm to the second pivot arm. The floor suspension system further includes a spring assembly having a spring pack pivotally coupled to the fork frame and the battery compartment.

Lift trucks are designed with a common chassis and can accommodate different form factors and different energy sources. According to one example, a chassis for a configurable sit-down counterbalanced forklift truck comprises a front side, a rear side, a left side, and a right side. A chassis compartment is situated between the front side and the rear side and between the left side and right side of the chassis. The chassis compartment is configured to fit within the chassis compartment one of a plurality of different types of power plants for the forklift truck and one of a plurality of different types of power sources. The chassis compartment is configured to hold one of a plurality of different designs of counterweights on or in a rear portion of the chassis compartment. The chassis is configured to support one of a plurality of different operator compartment modules attached atop the chassis.

The present invention provides a pallet carrier, comprising a carrier frame structure; a fork structure disposed on the carrier frame structure; a driving wheel structure comprising driving wheels that are articulated to the carrier frame structure, wherein each one of the driving wheels is set as a one-piece wheel structure integrated with a driving motor and a hub. The pallet carrier has the advantages of simple structure and work reliability.

A water bottle lifting and rotating device includes a base supporting a pair of rolling wheels and forwardly extending supports. The base further supports a vertically extending mast upon which a bottle clasp is lifted and lowered by a cable arrangement. A drive motor also supported on the base is operative in combination with the pulley and cable arrangement to raise and lower the bottle clasp and thereby raise and lower a captive water bottle. The bottle clasp supporting a water bottle is automatically rotated to an inverted position by a gear and gear rack arrangement operative between the mast and the bottle clasp.

A system for managing an inventory of carpet rolls within a warehouse includes one or more autonomous lift trucks, a database configured to store location information for a plurality of carpet rolls in the warehouse, a server in electronic communication with the database, and a system manager configured to send one or more instructions to the one or more lift trucks. The one or more autonomous lift trucks include a frame, a mast attached to the frame, a pole fixedly mounted on the mast, the pole being configured for insertion within a core of a carpet roll for transport of the carpet roll, a plurality of imaging devices mounted on each lift truck in a displaceable manner, at least one navigation sensor, at least one safety sensor, at least one emergency stop, and at least three wheels.

This piece of machinery (1) comprises a system for lifting people or loads (5) and a first stand-alone electrical power source that is used to make the piece of machinery function. A second location (8) allows an optional second stand-alone electrical power source (15) to be removably accommodated. The latter is selectable from a plurality of different second sources not exclusively made up of engine generators and not exclusively made up of devices for storing electrical power. It for example allows the first stand-alone electrical power source to be recharged or the piece of machinery to be powered together therewith. The piece of machinery comprises a system for identifying the second stand-alone electrical power source among the plurality of second sources accommodated in the second location (8). On-board electronics manage the delivery of electrical power to the piece of machinery by the second source depending on the second source identified.
