Smoother Ride
Hydraulic elevators combine the advantages of hydraulic systems with the ease of roped ones. A hydraulic pump is connected to a piston and pulley, while the piston is supported by a pedestal and connected to the hoist way by a series of brackets. A pair of steel cables are anchored to the floor of the shaft, stretched around the pulley at the top, and then attached to the bottom of the L-shaped sling on which the cab sits. The result of installing this system is that the customer gets a smoother ride than many other systems.
