A cart may include: a carriage; a wheel supported by the carriage and touching ground; a holding member rotatably supported by the carriage about a steering axis and rotatably supporting the wheel about a rotation axis; a steering handle to be gripped by a user; an input sensor configured to detect an operation on the steering handle by the user; a steering motor configured to be actuated in response to the operation by the user detected by the input sensor; and a transmission mechanism connecting the steering motor and the holding member and configured to rotate the holding member about the steering axis in response to actuation of the steering motor. The steering handle and the transmission mechanism may be mechanically separated, and the transmission mechanism may include a torque limiter interposed between the steering motor and the holding member.

A trolley as disclosed for manual transport of loads. The trolley comprises one or more wheels, an axle, a pair of handles which extend upwardly when the trolley is in an upright, non-travel position, a load carrying frame extending forward from the handles, and a pair of spaced support legs extending down from the load carrying frame and positioned either side of the one or more wheels. The support legs are adapted to support the load carrying frame substantially parallel to a support surface, such as the ground, when the trolley is in the upright, non-travel position.

A self stabilizing system which has an incompressible coil at least partially encompassed in a housing, and which controls a foot of a device to be stabilized. The coil abuts a plunger, which plunger is for allowing a user to selectably lock the elevation by use of a pin which fits within a plurality of annular grooves on the plunger. In a first embodiment, a pair of coils surround the plunger on either side and control a pair of feet, thus allowing automatic stabilization on an uneven surface. In a second embodiment, a single coil is controlled by a spring which abuts the plunger allowing a spring-loaded system for selecting an elevation to lock the plunger.

Carrying arrangement for carrying apparatuses, in particular medical apparatuses, having a base carrier on which at least three roller elements are arranged in order to move the carrying arrangement with respect to a floor surface. The roller elements are each rotatable about first axes of rotation (D). At least one of these roller elements is pivotable about a pivot axis (S) with respect to the base carrier. The axes of rotation (D) and the pivot axis (S) extend in different directions. At least one supporting element is arranged at least indirectly on the base carrier. The supporting element does not contact the floor in a first position of the carrying arrangement with respect to the floor surface and the supporting element contacts the floor in a second position of the carrying arrangement with respect to the floor, the second position being pivoted with respect to the first position.

A wheel guard is provided for use on a material handling vehicle comprising a steering assembly, an axle extending through the steering assembly and a steer wheel mounted on the axle. The wheel guard may comprise: a front plate to be positioned adjacent to the steer wheel; an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the vehicle axle is to be extended, the wheel guard to be rotatable about the axle; and a stop coupled to at least one of the front plate or the axle support to limit rotational movement of the wheel guard about the axle.

A cart for supporting a part to be inspected in a non-destructive testing (NDT) machine. The cart includes a base with wheels, a first support extending upright from the base, a second support extending upright from the base, and mounting fixtures being removably attachable to the first and second supports and having mounting ends engageable with the part to support the part from the first support or the second support. The base is displaceable with the wheels to enter and exit the NDT machine. The cart is lockable upon being within the NDT machine to secure the cart in position.

A robotic cart platform with a navigation and movement system that integrates into a conventional utility cart to provide both manual and autonomous modes of operation. The platform includes drive wheels replacing the front wheels of the cart. The platform and system include motors, encoders, an IMU, a processor and a microcontroller. The system has a work environment mapping sensor and a cabled array of digital cameras, proximity or radar sessors, as well as weight sensors, lights, a 15 key control panel secured throughout the cart. When in autonomous mode, the system provides navigation, movement and location tracking with or without wireless connection to a server. Destination keys allow autonomous navigation to desired destinations. Looping, boomerang and home keys facilitate autonomous navigation for a variety working environments and situations. The radar sensors provide enhanced obstacle avoidance, cart localizing, route planning and human interaction capabilities.

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 tipping prevention unit that prevents tipping of an image forming apparatus includes shafts holding a wheel of the image forming apparatus, a shaft that abuts the image forming apparatus at a position higher than the shafts, and a shaft that contacts a floor surface on which the image forming apparatus is placed at a position further protruding to the outside of the image forming apparatus than the wheel of the image forming apparatus.

A wheel guard is provided for use on a material handling vehicle comprising a steering assembly, an axle extending through the steering assembly and a steer wheel mounted on the axle. The wheel guard may comprise: a front plate to be positioned adjacent to the steer wheel; an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the vehicle axle is to be extended, the wheel guard to be rotatable about the axle; and a stop coupled to at least one of the front plate or the axle support to limit rotational movement of the wheel guard about the axle.
