Items such as loaves of bread are typically held for transport in a plastic crate. Often such crates are stacked on one another in a factory-bakery, a warehouse, a freight vehicle or a retail outlet. It can be problematic move stacked crates as lifting machinery is often not able to adequately hold on to them. If they are not held securely then crates may drop from the stack, which is inconvenient, not to mention a safety hazard. An object of a preferred form of the invention to address this problem by way of a crate lifter 1 comprising a main support mast 3, a carriage 8 engaged with the mast and rollers 6, 7 that enable the lifter to be moved. The carriage has clamps 9 adapted to move laterally with respect to the mast 3 to grip one or more crates 2 so that the crate(s) can be moved by the carriage up and down the mast. The carriage has a keeper 14 arranged such that it is caused to swing in response to the clamps 9 engaging the crate 2, or the lowest crate to be moved if there is more than one, to bring a ledge 14b of the keeper 14 into engagement with that crate to prevent it dropping free from the carriage.

Controlling a maximum vehicle speed for an industrial vehicle includes determining, by a processor of the industrial vehicle, a torque applied to the traction wheel of the industrial vehicle; converting the torque to an equivalent force value; and determining an acceleration of the industrial vehicle while the torque is applied to the traction wheel. Additional steps include calculating a load being moved by the industrial vehicle, based at least in part on the acceleration and the equivalent force value; and controlling the maximum speed of the industrial vehicle based on the calculated load being moved by the industrial vehicle.

The invention relates to an industrial truck comprising a mast, a load-carrying apparatus, which can be moved upwards and downwards thereon and which has at least one load-receiving assembly for receiving a load that is to be transported, and a support structure connecting the load-receiving assembly to the mast, the load-receiving assembly having a load-carrying arrangement connected to the support structure, and a device for reducing vibrations, characterised in that the device for reducing vibrations has at least one load support, which covers the load-carrying arrangement at the top at least in regions, on which support a load received by the load-carrying apparatus can be supported and which support is provided so as to be movable to a limited extent on the load-carrying arrangement such that it can perform vibration-reducing movements relative to the load-carrying arrangement.

The invention relates to a cargo handling vehicle for handling cargo within narrow aisles. The cargo handling vehicle comprises means for autonomous navigation, a chassis having at least two pairs of ground engaging means, a lifting boom. The lifting boom having a first end and a second end wherein the first end is arranged to the chassis and the second end is provided with a lifting unit. The first end of the lifting boom is attached to the chassis enabling movement of the second end in a vertical and horizontal direction, and the lifting unit is arranged rotatably in a horizontal plane. Each of the ground engaging means are independently steerable and individually driven by a respective driving means. Further, the invention also relates to a method in a cargo handling vehicle.

An intermodal container mobilizer that includes a tow vehicle and forward and aft intermodal shipping container attachments. The forward container attachment is carried by the tow vehicle and connects to one end of an intermodal container. The aft container attachment is wheeled and connects to an opposite end of the intermodal container. The forward and aft attachments, together with the tow vehicle, support the intermodal container for rolling transport across a flat surface.

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.

A conveyance apparatus according to an embodiment includes a fork unit, a lift unit, a movable cart unit, an auxiliary leg, and a distal end support mechanism. The lift unit is configured to drive the fork unit upward and downward. The movable cart unit is configured to support the lift unit and be movable on a traveling surface by driving a drive wheel. The auxiliary leg unit is provided for the movable cart unit, and is movable along a longitudinal direction of the fork unit and having an auxiliary wheel a position of which is changeable relative to the movable cart unit. The distal end support mechanism is provided on a distal end side of the fork unit and is switchable between a non-contact state with the traveling surface and a contact state with the traveling surface.

A wheel assembly for an outrigger of a material handling vehicle, comprising a first axle, a first wheel mounted on the first axle and a second wheel mounted on the first axle, whereby the first wheel and the second wheel rotate independently, and a second axle, a first wheel mounted on the second axle and a second wheel mounted on the second axle, whereby the first wheel and the second wheel rotate independently, wherein the first axle and the second axle are mounted on the outrigger, in tandem.

A work machine includes a base, a mount coupled to the base, wherein the mount is configured to support an arm. The arm is pivotally coupled to the mount, and includes a boom and an engagement mechanism positioned at the head of the boom. The mount is configured to raise and lower the arm relative the base. The engagement mechanism may include an extendable grabber to interface with one or more objects and lift and position the objects using the mule. The work machine may include a leveling system coupled to the base. The leveling system is configured to stabilize the base in an approximately level position, and includes a plurality of outriggers positionable between a stowed position and a deployed position. A first total width of the work machine in the deployed position is greater than a second total width of the work machine in the stowed position.

A pallet jack assembly for use with a pallet jack is provided. The pallet jack assembly includes a tug assembly configured for attachment to a towing vehicle and a frame assembly configured to support the tug assembly. A plurality of caster assemblies is supported by the frame assembly. Each of the caster assemblies is configured to support a wheel. The pallet jack assembly facilitates use of the pallet jack as a hand-powered pallet jack or for towing by a towing vehicle.
