Compact tool carriers having a loader mounted to a low-profile mainframe are disclosed. In some embodiments, the pivot points of the mainframe about which the loader is pivoted are low relative to the mainframe to reduce the mainframe size and to lower the center of gravity to improve the stability of the compact tool carrier during use.

Systems and methods for towing, hitching, and connecting devices are described. An autonomous guided vehicle includes an automated hitch capable of connecting to a variety of types of containers.

The initial setting method for the unmanned forklift includes a step of acquiring a measurement value of floor surface inclination of a stop position where the unmanned forklift stops when the unmanned forklift unloads a palette on a rack, a step of setting the stop position where a predetermined inclination pattern is detected, as a precise adjustment position, from the acquired measurement value, a step of causing the unmanned forklift to unload the palette in accordance with an operation program, and measuring a deviation amount of the palette unloaded by the unmanned forklift, at the precise adjustment position, and a step of correcting a command value of the unmanned forklift at the stop position, based on the measured deviation amount.

A leveling system for a lift device includes a control system. The control system has programmed instructions to acquire operation data regarding operation of the lift device, fluidly couple a first leveling actuator and a second leveling actuator based on the operation data, acquire an update regarding the operation data, fluidly decouple the first leveling actuator and the second leveling actuator based on the update regarding the operation data, and selectively control the first leveling actuator and the second leveling actuator to (i) selectively reposition a first tractive element and a second tractive element relative to each other about a longitudinal axis defined by the lift device and (ii) selectively reposition the first tractive element and the second tractive element about a first lateral axis defined by the lift device.

The movable lifting system (1, 2) comprising a telehandler (1) which in turn comprises: a movable lifting arm (11) provided at a distal end, with a coupling device (111) for the removable fixing of equipment (112) or of the type adapted to grip loads, such as a fork, grippers or the like, or of the type suitable for lifting persons and work tools such as a basket or the like; and a powertrain assembly for movement on the ground. The system (1, 2) further comprises: control means, arranged on board the telehandler (1), provided to manage the operation of the powertrain assembly, adapted to receive command signals and adapted to regulate the operation of the assembly according to the command signals; and command means (2), separate from the telehandler (1), to be activated by an operator (3) and predisposed to produce the command signals.

A materials handling vehicle includes a mast, a load handling structure supported on the mast, one or more operator controls, and a lifting structure having a chain structure for performing a lifting and lowering of the load handling structure. The materials handling vehicle further includes a height sensor for generating a height signal corresponding to vertical movement of the load handling structure relative to the mast, and a vehicle control module for processing the height signal received from the height sensor and an operator control signal received from the one or more operator controls. The vehicle control module evaluates the height signal and the operator control signal and disables one or more vehicle functions if the height signal does not correspond to the operator control signal.

The present disclosure provides an onboard object measurement system for a vehicle, such as a lift truck. The vehicle may have one or more sensors incorporated thereon, such as within one or more load handling fixtures. Control circuitry associated with the vehicle and/or the sensors is configured to receive data from the first sensor corresponding to changes in force in the first axis, receive data from the second sensor corresponding to changes in force in the second axis, correlate the changes in force along the first and second axes, and to determine one or more of a direction of motion, a thrust, or a position of a center of gravity associated with the load based on the correlation.

A low-lift industrial truck (2) and a method for operating the same. The industrial truck includes a load fork (4) for picking up a load. Fork tines (6a, 6b) of the load fork (4) each include at least one load roller (8) in a region of fork tine tips (28). The industrial truck also includes a load lifting assistance system having a distance sensor (16) and a processing unit (14). The distance sensor is configured to measure a distance between the load and a front wall (12) of the industrial truck facing the load fork. At least one distance between the load and the front wall is saved in the processing unit and corresponds to a predetermined stop position. The processing unit is configured to process measured values of the distance sensor and to generate a stop signal when a distance corresponding to the stop position (20a, 20b) is determined.

A method for calibrating a sensor unit disposed on a load-bearing device of an industrial truck includes the steps of: determining a first position of the sensor unit relative to an object located remotely from the industrial truck, displacing the sensor relative to the object in a first direction by a first distance, determining a second position of the sensor unit relative to the object, determining the spatial position or arrangement of the sensor unit relative to the load-bearing device based on the first and second positions, the direction of movement, and the distance between the first and second positions.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.
