The wheel and the rollers are rigidly fixed relative to one another. Each trolley (12) has a geometry such as to cause a rotation moment around the upper wheel (13) when the trolley traverses sloped sections of rail to increase the force of contact or traction of the driving wheel (13) on the rail.

Abstract: A bottom flange running gear of a monorail has load-bearing running wheels on both sides of a preferably I-shaped running rail. Such a running gear has front and rear lateral guide rollers mounted on preferably vertical axles and in contact with the running rail. A preferably unilateral or one-sided load may be applied to the running gear, preferably by a traction motor. The invention proposes that at least one supporting roller carrier, preferably on the sidepiece of the running gear opposite the traction motor, can be linked coaxially to the axle of one of the guide rollers. The invention further proposes that a supplemental guide roller can be in contact, preferably under the force of a laterally positioned spring on the running rail, against the edge of the bottom flange of the running rail. Additionally, a supporting roller, mounted on a preferably horizontal supporting roller axle, may be in contact, from below, against the bottom flange of the running rail.

Abstract: A device for shipping suspensible piece goods has an elongated trolley which can travel along an overhead rail. A rod is fixed to either longitudinal end of the trolley and depends from the latter. The end of each rod remote from the trolley has an upwardly open hook-shaped portion. A carrier is removably suspended on the hook-shaped portions and has a cutout which allows goods to be suspended from the carrier. Once the carrier has been loaded, the entire shipping device can be placed in a truck for transport as a unit. A downwardly open hook-shaped element projects laterally of the carrier from the hook-shaped portion of each rod. These hook-shaped elements can be used to suspend the shipping device from a bar in the truck. Since the hook-shaped elements are located laterally of the carrier, the shipping device tilts to one side when it is suspended from the bar. The shipping device and its suspended goods then take up less room in the vertical direction thereby increasing the loading capacity of the truck.

Abstract: A suspended personnel carrier includes an elevated cylindrical track from which a carrier is suspended for translation by a bearing assembly. The bearing assembly includes orthogonal rollers which ride along the cylindrical track. The carrier is propelled along the track through a fan drive system including a propeller and a motor.

The drive motor and propeller are coupled to the frame of a carrier by a slip rail assembly, and to the bearing assembly by a shock absorbing telescoping linkage, such that drive force is first transmitted to the bearing assembly, rather than the frame.

Abstract: A cable car type vehicle arrester features a pair of trumpet bars which are interconnected by a link which either maintains the distance between the bars constant or reduces same upon one of the bars being deflected outboard of its home or rest position. This reduces the free swinging time of the vehicle between bars and increases the distance through which the bars subsequent to the initial deflection are deflectable by the vehicle. This accordingly increases the stroke of shock absorbers associated with the bars increasing the conversion of the kinetic energy of the vehicle. Casters can be provided to support the bars to allow longer lighter bars with less robust bearing and structural members. The casters can be run on a corrugated surface to cam the bars vertically further increasing the kinetic energy conversion and endow a self-centering action on the arrester.
