To realize a fork lift device capable of contributing to space-saving for an aisle width at a warehouse. A fork lift device according to an embodiment of the present includes: a first fork and a second fork moveable in a lateral direction and a vertical direction with respect to a traveling direction; and an interchanging mechanism configured to interchange vertical positions of the first fork and the second fork.

Typically, unit loads with wooden pallets in warehouses are moved by pallet lifters or AMRs which are bulkier in size and require more power with high operating costs. This disclosure relates generally to a unit load lifter designed with counterbalance arm mounted on an autonomous mobile robot (AMR) to load and unload unit load from one position to another position autonomously. The unit load lifter includes a horizontal slide unit and a vertical axis fork assembly. The horizontal slide unit include base plate of the unit load lifter is mounted on the AMR. A plurality of fixed guides is integrated with the base plate to house the vertical axis fork assembly by a plurality of rollers on a roller mounting plate. The vertical axis fork assembly include an actuating end of a linear actuator is connected to the sliding plate to drive the at least one fork up and down.

Material logistics system for coordinating transfer of production material so that production material is available as needed at production stations of a manufacturing facility, in particular a series production facility. Thus, multiple sensors are provided for sensing a production material supply at production stations, as well as a central unit in signal-transmitting connection with the sensors and which, based on output signals transmitted from the sensors, determines logistics data relating to the production material for a particular production station. And also, using logistics data, generates control signals for the transfer of production material and provides them for further data processing units. Furthermore, the central unit uses logistics data to control a driverless transport vehicle, having a transport rack including a transport level, for transporting production material accommodated in containers, for a partially automatic container transfer between a transport rack and a storage rack of a production station.

Some illustrative embodiments of a fire tube implement for extraction and insertion of a fire tube may include an elongate shaft that is configured to extend outward and to be received within an opening in the fire tube. In some embodiments, the elongate shaft may carry at least one extender that is moveable between an extended position and a retracted position normal to a longitudinal axis of the elongate shaft. The at least one extender may be configured to engage an internal surface of the fire tube within the opening when the at least one extender is in the extended position. In some embodiments, a stabilizer may be laterally disposed from an exterior surface of the elongate shaft and securable to the fire tube. The elongate shaft may be operable by a powered machine.

Method for securing a first and a second upright, including the following steps of a) attaching the connectors and b) adjusting the position of the first upright and the position of the second upright such that the first lower end of a first climbing element and the second lower end of second climbing element lie in a plane substantially orthogonal to a climbing direction.

Apparatus for installing a solar panel array in parallel rows on panel support structure, as for solar farms, including a lift-and-place vehicle with characterizing features for moving between and along rows of support structure. Such vehicle includes a driven ground-engaging base, a lifting mast extending upwardly and in a fore/aft direction to define a panel-loading space therebeneath, a liftable trolley beam secured to the mast over the panel-loading space and extending laterally between adjacent rows, a traversing trolley movable along the beam, and a panel-placing carrier suspended from the trolley for up/down and lateral movement of carried panels. A panel-pallet vehicle is hitched to the lift-and-place vehicle, extends under the panel-loading space, and has a pallet carrier adjacent to the panel-loading space. Preferred embodiments include telescoping, tilting and angle adjustment of the mast, and the panel-placing carrier has panel supports movable between panel supporting and releasing orientations, and wireless control.

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.

An exemplary embodiment may provide a robotic powered cargo handling system. An embodiment may implement a pallet-lift mechanism to lift cargo or pallets. Powered rollers may be embedded into the forks of a pallet-lift mechanism and on top of the vehicle body. An exemplary embodiment may be fully autonomous. A user or software may direct the vehicle to a pallet or piece of cargo and set a destination for the cargo. Sensors, cameras, GPS, and computer vision may be implemented to navigate and avoid obstacles. An exemplary embodiment may include independent 4-wheel steering, 4 corner height adjustment, in-hub electric motors, and pneumatic or solid tires.

Truck mounted forklift (200) for mounting on the rear of a vehicle. The truck mounted forklift comprises a u-shaped chassis (201) with a linkage (103) lifting assembly mounted thereon. The linkage lifting assembly comprises a carriage (101) slidably mounted on the chassis and a linkage, the linkage comprising a first link (105) connected to the carriage by a pivot joint (107) and a second link (109) connected to the first link by a pivot joint (111). A fork carriage (113) is connected to the other end of the second link. The second link comprises a telescopic link having a plurality of link sections nested together. Cylinders (115,117) are provided to operate the links and the telescopic link. The linkage is more compact than other duplex (i.e. two part) linkages, will not protrude rearwardly increasing the overhang of the forklift and will be able to be mounted and dismounted in a substantially vertical direction, obviating the need for reinforced, heavier tines.
