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.

A cargo transport system is provided that has an ability to move cargo in an autonomous or semi-autonomous manner, using a compact lift vehicle capable of lifting relatively heavy objects. The system includes a cargo loading system, a sensor suite coupled with a controller, dunnage detection, cross-decking capability, cargo stacking capability, autonomous navigation, tip detection and prevention, or any combinations thereof. The system may include a fork assembly coupled with a mast and movable in a vertical direction relative to the mast. Further, the mast may be coupled with a platform or deck and movable in a horizontal direction relative to the platform, to allow the fork assembly to be lowered below a top plane of the platform when the mast is at a forward location relative to the platform. The controller and sensor suite and may provide for autonomous or semi-autonomous control and movement of the cargo transport system.

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 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.

A transfer driver includes a transfer drive transmission mechanism drivingly coupled to a contact section, and a transfer drive source configured to drive the transfer drive transmission mechanism. A guide driver includes a guide drive transmission mechanism drivingly coupled to a pair of guide sections, and a guide drive source configured to drive the guide drive transmission mechanism. The transfer drive source and the guide drive source are disposed on a transfer-direction scooping side relative to a holder, and the transfer drive transmission mechanism and the guide drive transmission mechanism intersect each other in a vertical view at an intersection portion, and are adjacent to each other in a vertical direction at the intersection portion.

A machine for handling heavy components in a heavy equipment environment. In an example implementation, the machine includes a truck having at least two front wheels and at least one rear wheel. A outrigger portion extends forward from the truck. The front wheels are attached at a forward end of the outrigger portion. A mast extends vertically from a track extending forward from the truck on a base of the outrigger portion. The mast is movably extendable or retractable along the track. A carriage is mounted on the mast and configured to move vertically on the mast. A pair of forks are mounted on the carriage to move vertically when the carriage is controlled to move. A personnel platform is mounted on the carriage independent of the mounting of the forks on the carriage. A remote control panel is configured to override a cab control panel under operator control. The remote control panel includes a plurality of controls for moving the carriage and for extending or retracting the mast.
