An industrial vehicle includes a body, an axle pivotally supported by the body, a lateral acceleration sensor determining lateral acceleration applied to the body when the industrial vehicle is turned, an actuator temporally restricting pivoting of the axle while the industrial vehicle is being turned, a vehicle speed limiter limiting traveling speed of the industrial vehicle when the industrial vehicle is turned, and a controller driving the actuator based on the lateral acceleration determined by the lateral acceleration sensor to temporally restrict pivoting of the axle and to limit traveling speed of the industrial vehicle based on the lateral acceleration. In the controller a first lateral acceleration threshold value which is used in judging whether traveling speed of the industrial vehicle should be limited is set larger than a second lateral acceleration threshold value which is used in judging whether pivoting of the axle should be temporally restricted.

According to an embodiment, a transport device includes: a vehicle body including a fork portion that supports a load, a lift portion that drives the fork portion up and down, a movable carriage portion that supports the lift portion, and is movable on a traveling surface by driving a drive wheel, and an auxiliary leg portion that is provided in the movable carriage portion, is movable along a longitudinal direction of the fork portion, and has an auxiliary wheel having a variable position with respect to the movable carriage portion; and a control unit that, in a case where a step is present on the traveling surface, controls operations of the lift portion, the movable carriage portion, and the auxiliary leg portion such that the movable carriage portion climbs the step, based on the position of the center of gravity calculated by a calculation unit.

A carrying mobile robot includes a frame, a suspension system disposed at the bottom of the frame, and a lifting mechanism disposed on the frame. The suspension system includes two suspension mechanisms disposed on the left and right sides, each of which includes a supporting beam, a driving wheel, a connecting member and a first driven wheel. The first driven wheel and the driving wheel respectively support the front and rear ends of the supporting beam, and the connecting member is connected to the supporting beam and located between the driving wheel and the first driven wheels. The lifting mechanism includes a plurality of lifting members, a first driving system for driving the lifting member and a transmission system for transmitting the driving force of the first drive system to the lifting members.

The present invention relates to a transport device (100) for transporting one or more handling devices, each for handling a pallet (300) and/or a workpiece (1) on a machine tool (1000) which is set up on a base surface for machining the workpiece (1), wherein the transport device (100) is freely movable on the base surface for positioning the one or more handling devices relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

This disclosure includes a shock damping system that has a pressure storage reservoir, a check valve in fluid communication with the pressure storage reservoir, and a needle valve in fluid communication with the pressure storage reservoir. The needle valve is in a parallel fluid-communication configuration with the check valve.

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.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end, a second actuator coupled to the first end, a third actuator coupled to the opposing second end; and a fourth actuator coupled to the opposing second end. The first actuator and the second actuator are selectively engageable to facilitate providing active control of a first pitch adjustment and a first roll adjustment of the first end of the chassis. The third actuator and the fourth actuator are (i) selectively fluidly couplable to facilitate providing passive control of a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis and (ii) selectively fluidly decouplable to facilitate providing active control of the second pitch adjustment and the second roll adjustment of the opposing second end of the chassis.

A support system for a vehicle includes a base and at least a first and a second support arm. Each of the first and the second support arms include a base end pivotally coupled to the base through a respective hinge assembly. Each of the first and the second support arms further include a distal end opposite the base end. The support system also includes a respective wheel assembly coupled to each distal end. Each wheel assembly includes an independently powered and steerable wheel configured to engage a travel surface, a propelling motor configured to drive a respective first support arm between a stowed condition and a deployed condition unaided while the vehicle remains stationary, and a steer actuator configured to change an angle of the wheel with respect to a respective support arm.

Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.
