A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1,200 people per hour at rope speeds of up to 2.5 m/s (8.2 ft/s). [2] The four person detachable chairlift ("high-speed quad") can transport 2,400 people per hour with an average rope speed of 5 m/s (16.4 ft/s). [ 3 ]
Single bulkhead cylinders, typically built prior to a 1972 ASME A17.1 Elevator Safety Code change requiring a second dished bulkhead, were subject to possible catastrophic failure. The code previously permitted only single-bottom hydraulic cylinders. In the event of a cylinder breach, the fluid loss results in uncontrolled down movement of the ...
A gas lift chair is a form of office chair that allows the user to modify their height in relation to the height of a desk, leading to an increase in comfort and ergonomic benefit. A patent describing a common configuration of a gas lift cylinder by John Wang, published 20 May 1989.
A patient lift (patient hoist, jack hoist, Hoyer lift, or hydraulic lift) may be either a sling lift or a sit-to-stand lift.This is an assistive device that allows patients in hospitals and nursing homes and people receiving home health care to be transferred between a bed and a chair or other similar resting places, by the use of electrical or hydraulic power.
A gas spring consists of a sealed cylinder filled with a charge of high-pressure [5] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
The machining and additional production steps associated with “gun drilling” the piston rod can add cost to the finished cylinder. Magnetostrictive LDTs provide extremely high accuracy, down to one micron. [3] Hydraulic cylinder with a Hall effect sensor mounted along its barrel to sense position of a magnetic piston inside. The sensor is ...

Rabbit tool Hydraulic spreading tool that is specially designed to open doors that swing inward. [15] Red line See booster hose Reducer Adapter used to attach a larger diameter source hose to a smaller diameter receiving hose.
