Hoist atop an elevator. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist , although some pump hydraulic fluid to raise a cylindrical piston like a jack .
The Mitsubishi Electric-owned Solae Test Tower (173 m) in Inazawa City, Japan, is the world's 4th tallest elevator testing tower after Hyundai elevator test tower at Icheon plant (205 m) South Korea, the Kone Tytyri test tower (235 m) and the Rottweil Test Tower (246 m).
A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.
In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...
The lift operators at the terminals of a chairlift communicate with each other to verify that all terminals are safe and ready when restarting the system. Communication is also used to warn of an arriving carrier with a passenger missing a ski, or otherwise unable to efficiently unload, such as patients being transported in a rescue toboggan ...
Yan Lift, known in its later years as Lift Engineering, built 31 high speed quads between 1987 and 1994, mostly in the United States and Canada. The detachable grips were of an unusual design, in which a steel bar with V-shaped troughs sat atop the haul rope and were held in place by tensioning assembly with rubber springs.
