A cable car carriage for transporting goods or passengers has two opposing spaced-apart crawlers. Each of the crawlers has a crawler chain composed of juxtaposed chain links. A support cable can be inserted between the opposing crawlers on the opposing chain links of the crawler chains. A pressing mechanism connects the crawlers with one another, and is designed to adjust the distance between the crawlers as well as the pressing force of the two crawlers relative to each other and/or the pressing force of the two crawlers against the support cable. The crawler chains are driven in a circulating movement by a drive via a crawler running gear, thus moving the cable car carriage along the support cable. A cable crane, a passenger gondola, a cable saddle, and a transport assembly employing the cable car carriage are also disclosed.

A pre-compression type emergency air spring assembly includes an upper cover plate, an air bag, an upper end plate, and a lower end plate. A periphery of the upper end plate is connected with a periphery of the lower end plate through the air bag. A top part of the upper end plate is provided with transverse pre-compression cavities and transverse pre-compression plates arranged at transverse openings of the transverse pre-compression cavities. The transverse pre-compression cavities are internally provided with laminated spring elastomers through the transverse pre-compression plates in a pressing mode. Multiple steel springs are arranged between the upper cover plate and the upper end plate in a pressing mode along a circumferential direction of the laminated spring elastomers. The upper cover plate is arranged on a periphery of the transverse pre-compression cavities in a sleeving mode.

A suspension assembly for a cycle having improved stability includes a steering fork having a first arm and a second arm, each of the first arm and the second arm having a fixed pivot and a shock pivot, the space between the first arm and the second arm defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit having a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. A gas pressure inside the shock gas spring is equal to a predetermined pressure for a user's body weight to produce optimal ride conditions for the user's body weight.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.

The invention relates to a spring-damper element (2) for mounting a punching press (1), with a hydraulic damper unit (3) with a first fluid chamber (4) and a second fluid chamber (5), wherein, in the intended operation, a hydraulic fluid is displaced from the first fluid chamber (4) via a throttle point (6) into the second fluid chamber (5) when the spring-damper element (2) is compressed. The damper unit further comprises an overload valve (7) arranged between the first fluid chamber (4) and the second fluid chamber (5), which overload valve opens when a specific fluid pressure is reached in the first fluid chamber (4) or when a specific pressure difference is reached between the first fluid chamber (4) and the second fluid chamber (5) and releases a bypass (8) via which hydraulic fluid then flows from the first fluid chamber (4) into the second fluid chamber (5) bypassing the throttle point (6). Thereby, the spring-damper element (2) is designed in such a way that the fluid pressure or the pressure difference, respectively, at which the overload valve (7) opens can be adjusted when the spring-damper element (2) is installed as intended. With such spring-damper elements according to the invention, it becomes possible to create a mounting arrangement for a punching press, the damping characteristics of which can be adjusted without significant effort, such that a variable operation of the press in wide ranges becomes possible while keeping the ground loading to a minimum in each case.

The invention provides a vibration isolation system (IS), comprising a piston (402) to carry a payload, a connecting member (410), a spring (404) and a flexible member (408). The spring is arranged to support the piston along a direction with a positive stiffness. The flexible member is arranged to apply a force to the piston along the direction via the connecting member with a negative stiffness.

A shock strut is provided that includes a first energy absorption stage or load limiter and a second energy absorption stage or load limiter. The second energy absorption stage or load limiter can include one or more disc springs. The shock strut can be employed on both fixed and retractable landing gear alike, while providing design adjustability for obtaining load-deflection curves that accommodate a range of descent or impact velocities.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.
