[ii] The other side was filled with hydraulic fluid. When the launch valve was triggered, the hydraulic fluid pressure dropped rapidly as fluid was vented into an unpressurised catch tank. The piston was forced rapidly from the air end to the hydraulic end, pulling the crosshead and the jigger pulleys and drawing the launch trolley forwards.
Acting as gantry, the lifting frame included a number of work platforms from which crewmen serviced the rocket. Three (later two) platforms folded flat against the lifting frame, and could be folded out from the elevated lifting frame with the use of a hand winch. Each folding platform included a safety rail of folding posts and chains.

An air winch, sometimes known as an air hoist or air tugger, is an air-powered version of a winch. It is commonly used for the lifting and the suspension of materials. In the oil and gas, construction , and maritime industries, air winches are frequently preferred to electric, diesel, and hydraulic winches because of their durability ...
For lifting structures such as houses the hydraulic interconnection of multiple vertical jacks through valves enables the even distribution of forces while enabling close control of the lift. The screw version of the bottle jack works by turning a large nut running on the threaded vertical ram at the neck of the body.
Hydraulic motors usually have a drain connection for the internal leakage, which means that when the power unit is turned off the hydraulic motor in the drive system will move slowly if an external load is acting on it. Thus, for applications such as a crane or winch with suspended load, there is always a need for a brake or a locking device.
