摘要： A mobile transport system includes a vehicle frame, first and second pairs of support wheels, first and second drive wheels, and a swing frame. A drive unit including a drive frame is disposed on the swing frame. The first drive wheel is rotatably supported on a first swing arm, and the second drive wheel is rotatably supported on a second swing arm. The first and second swing arms are coupled to each other by a coupling unit, such that a pivot motion of the first swing arm about a first swing axis in a first pivot direction brings about a pivot motion of the second swing arm about a second swing axis in a second pivot direction oriented opposite to the first pivot direction.

摘要： A height-adjustable industrial caster wheel includes a mounting plate, a swivel assembly that swivels relative to the mounting plate, and a spring housing that is movable relative to the swivel assembly. The mounting plate or the spring housing is secured to the swivel assembly, such that the relative position of the swivel assembly and either the mounting plate or the spring housing can be controllably altered to change the overall height of the height-adjustable industrial caster wheel. If needed, a locking mechanism can be used to maintain the relative position between the swivel assembly and the mounting plate or the spring housing. The height-adjustable industrial caster wheel can be adjusted by accessing the height-adjustable industrial caster wheel from above, eliminating the need to raise the pallet truck away from the floor to be able to access and adjust the height-adjustable industrial caster wheel.

摘要： A wheel assembly attached to, or integrally formed with, the underside of an object for allowing the object to roll in one of at least two rolling directions includes a fixture and a wheel. The fixture has a first pair of spaced-apart axle mountings defining between them a first axial direction perpendicular to a first rolling direction, and a second pair of spaced-apart axle mountings defining between them a second axial direction perpendicular to a second rolling direction. The wheel has an axial projection extending from each side. The axle mountings and the axial projections are configured such that the wheel can be located with the axial projections retained by the first pair of axle mountings for allowing the object to roll in the first rolling direction, and alternatively, with the axial projections retained by the second pair of axle mountings for allowing the object to roll in the second rolling direction.

摘要： A self propelled toolbox is provided with a plurality of storage compartments for storing tools. The toolbox is supported by two pairs of wheels. Each wheel of one of the pairs of wheels is a driven wheel that is mechanically coupled to an electric motor that causes the driven wheel to rotate about an axis to propel the toolbox. Each wheel of the other pair of wheels is a castor that is not operably linked to an electric motor and can pivot about an axis for steering the toolbox when the toolbox is in motion. The toolbox contains an energy reservoir in circuit communication with the electric motor for providing power to the electric motor. The quantity of power provided to the electric motor is controlled by a current controlling means that is accessible external of the toolbox by an operator of the self propelled toolbox. The two driven wheels may each be driven by the same electric motor, or they may each be driven by an electric motor that is mechanically coupled to only that wheel.

摘要： A straddle carrier having an electric drive system, consisting of a lower and an upper frame, which are connected with one another by means of supports. A lifting mechanism with hoists is disposed on the upper frame, and the lower frame consists of chassis carriers having electrically driven wheels, and a power generation unit that feeds its generated electric power into a direct voltage intermediate circuit, to which current inverters for supplying the travel, lifting, and auxiliary motors are connected. The power generation unit represents a micro gas turbine having an attached power generator, the power of which is passed to the travel, lifting, and auxiliary motors. The straddle carrier can be produced at low weight and maintained under advantageous conditions. Furthermore, the straddle carrier can be operated under environmentally friendly conditions.
