Abstract: The invention relates to an in-house track-bound transporting system with self-propelling carriages that move on rails. The system has stoppers to prevent said carriages from crossing over open rail ends or track borders, and the system is provided with stops. The stoppers collide with the stops in order to prevent a crossing-over, said stops having first and second fixed stop elements. The stoppers can be moved between a first crossing-over position and a second crossing-over position such that the first stop elements can be crossed over in the first crossing-over position of the stoppers, and the second stop elements can be crossed over in the second crossing-over position of the stoppers, wherein the first stop elements cannot be crossed over in the second crossing-over position of the stoppers, and the second stop elements cannot be crossed over in the first crossing-over position of the stoppers.
Abstract: A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and net downhill acceleration of the trolley. The trolley may include a brake pad positioned to contact the cable. At the downhill end of the ride, the lever actuating the brake is caught and lifted by a capture ring, thus relieving the braking load on the trolley. Also, the trolley engages a comparatively modest, second resistance mechanism, such as, for example, a system of springs, that gradually increases in resistance with distance of motion of the trolley thereagainst, bringing the trolley to a gradual halt.
Abstract: A device and system for controlling travel of a railcar along a set of rails is provided. In one example, a railcar stop is coupled to the set of rails and is selectively movable between a first position wherein the railcar is free to travel along the set of rails and a second position wherein the railcar stop engages the treads of the wheels to thereby prevent travel of the railcar in at least one direction along the rails.

Abstract: A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and limit net downhill acceleration of the trolley. The trolley may include a brake pad positioned to contact the cable. At the downhill end of the ride, the lever actuating the brake is caught and lifted by a capture ring, thus relieving the braking load on the trolley. Also, the trolley engages a comparatively modest, second resistance mechanism, such as, for example, a system of springs, that gradually increases in resistance with distance of motion of the trolley thereagainst, bringing the trolley to a gradual halt at a rate to improve comfort of a rider and reduce acceleration forces (loads) on the trolley.

Abstract: Self propelled pallet vehicles (12a) are guided along a track network (10) by downwardly projecting guide pins (350, 352) carried by each pallet vehicle (12) which engage slots (354, 358) in the track network and steer the pallet vehicle (12) along the track network (10). The track network has main (20) and branch (22) track sections, and selective delivery of the vehicles to various destinations along the track network (10) is achieved by controlling the position of the guide pins (350, 352) between alternate rotated raised and lowered positions. In the lowered position the guide pins (350, 352) interact with the track network (10) to guide the pallet vehicle (12) into a branch section (20) of the track. In the raised position, the guide pins (350, 352) cause continued movement of the vehicle (12) along the main track section (22) and past a junction (38). The guide pin position may be controlled by a photoemitter (364) at the junction (38), or by various other alternatives.

Abstract: An energy absorbing apparatus is provided to dissipate the energy of the impact force of a vehicle. A plurality of energy absorbing sheets are arranged in a stacked relation to resist the impact force and to thereby dissipate the energy of the force. Each sheet has a honeycomb structure of hexagonal cells that are filled with a deformable material such as polyurethane foam and that are defined by walls of relatively rigid material. In operation, an impact force is applied to the stack of energy absorbing sheets and each sheet is thereby caused to cut or shear into its abutting sheet so that at least a portion of the energy of the impact force is dissipated. As the stacked sheets cut into one another, the energy of the force is further dissipated by the compression of the polyurethane foam of the sheets.
Abstract: A device for stopping a wheeled vehicle which runs on a guide rail, comprises a scotch block connected to the rail, against which the front wheel of the vehicle can strike. The scotch block in this position fits a part of the outer circumference of the wheel up a certain height. The scotch block is formed by two distinct parts, namely a lower part and an upper part, the lower part being fixed rigidly to the rail and the upper part being retractable from a high position to a low position and vice-versa by rotation about an axis. Movement from the low position to the high position is controlled by an operating component situated upstream from and immediately adjacent the lower part of the scotch block, which component is actuated by a front wheel of the vehicle.
