A load-carrying truck has a fork lift mechanism mounted on a chassis, a pair of front wheels (24, 26) and a single rear wheel (30). At least one front wheel (26) and the rear wheel (30) are driven wheels whose speed is varied relative to one another differently depending on whether the truck is being driven in a forward reverse mode with the front wheels (24, 26) aligned generally parallel to the front-rear axis of the chassis and with steering controlled by steering the rear wheel (30), or a sideways mode with the rear wheel (30) aligned generally perpendicular to the front-rear axis of the chassis and with steering controlled by steering the at least one of the front wheels (26). When the truck is operated in forward/reverse mode and is steered towards the side on which the driven front wheel (26) is located, the relative speed (26) of that wheel is decreased progressively and comes to a stop when the axis of rotation of the rear wheel (30) intersects the front wheel position, and is driven in reverse at increasing speeds as the axis of the rear wheel (30) passes that point of intersection with further increasing steering angle. In the sideways mode of operation when the truck is steered in the direction towards the rear end of the chassis, the relative speed of the rear wheel (30) is decreased progressively and comes to a stop when the axis of rotation of the steered front wheel (26) intersects the rear wheel position, and the rear wheel (30) is driven in reverse at increasing speeds as the axis of the steered front wheel (26) passes said point of intersection with further increasing steering angle.

A handling machine is provided. The handling machine includes a chassis, a front wheel shaft, a rear wheel shaft, two front wheels, two rear wheels, a load handling device, a driving cab, and at least one tank. The front wheel shaft and the rear wheel shaft extend transversely and are respectively fitted with the two front wheels and the two rear wheels. The load handling device is mounted on the front of the chassis. The driving cab is fastened to the chassis and is fitted with a seat. The driving cab includes a cab structure including two lateral arches, each lateral arch including a front upright and a rear upright connected to one another. The at least one tank is configured to contain pressurized gas, fastened to the chassis, and positioned between the rear upright of one of the lateral arches and one of the rear wheels.

An apparatus for loading, handling and transporting waste containers includes a vehicle having a main frame and a load container handler, the load container handler including a main frame assembly having a rear and mounted to and atop the vehicle main frame; a pivot assembly pivotally connected to the main frame assembly to rotate about a first axis; a main jib assembly connected with the pivot assembly to reciprocate along a first line between jib extended and retracted positions; a carriage assembly connected with the main jib assembly to reciprocate along a second line between carriage extended and retracted positions and including container connection elements operable to rotate about a second axis and for engaging with and holding a container; and, motive elements for moving the pivot assembly, main jib assembly and carriage assembly.

The present invention involves a narrow aisle truck comprising: a vehicle body having length and width directions; wheels assigned to the vehicle body and arranged on two axes running in the width direction and configured to drive and steer the truck; a drive system configured to exert an acceleration torque on at least one of the wheels; a mast extending substantially vertically with respect to the length direction of the vehicle body between the two axes; at least one detection unit to detect at least one state parameter; at least one actuator to cause a movement of the mast relative to the vehicle body; and a control unit to: determine a current state, determine an effect of an actuation of the at least one actuator on the current state, and activate the at least one actuator to reduce a difference between the determined current state and a predetermined target state.

A loading frame includes a rectangular u-shaped frame with an opening at one side, forks extendable and retractable between the closed side and the open side of the U-shaped frame, loading frame wheels on one arm of the U-shaped frame, and a truck interface on the other arm of the U-shaped frame. The loading frame wheels and truck interface support travel of the frame in a direction other than the direction of travel of the forks between the open and closed sides of the U-shaped frame.

An autonomous transport vehicle includes a frame forming a transport payload area of the vehicle. The payload area includes a payload contact support surface that defines a payload support plane that supports the payload. The payload area further includes an articulated underpick end effector that engages and underpicks the payload with respect to the support plane, and extends and retracts with respect to the payload area effecting payload transfer. Payload registration facets are mounted to the frame to engage the payload. The registration facets are disposed to provide, upon engagement with the payload, at least two degrees of registration capturing and securing the payload in a predetermined position in the payload area, and are configured to effect payload engagement with the at least two degrees of registration registering the payload substantially coincident with seating of the payload on the payload support plane of the payload area.

An electrically powered mast for a lift truck that includes one or more electrically powered actuators positioned within an outermost periphery of a vertically elongate frame of the mast, and selectively moving a carriage along the vertically elongate frame.
