Hydraulic elevators are elevators which are powered by a piston that travels inside a cylinder. An electric motor pumps hydraulic oil into the cylinder to move the piston. The piston smoothly lifts the elevator cab. Electrical valves control the release of the oil for a gentle descent.
Hydraulic elevators are used extensively in buildings up to five or six stories high. Sometimes, but rarely, up to 8 stories high. These elevators, which can operate at speeds up to 61 meters (200 ft) per minute, do not use the large overhead hoisting machinery the way geared and gearless traction systems do.
All modern hydraulic pumps are either equipped with a Solid-State Contactor or a mechanical Y-Delta starter. Solid-State Contactor starters are better for the motor and the building's power supply, as the windings last longer and there are no voltage drops across the line of the building's power supply. Y-Delta starters use two contactors to start the motor on a reduced speed, then kick on full speed. Old hydraulic elevators just started up abruptly, sending mains power at full blast right into the motor. This puts a lot of strain on the motor which, in turn, makes it burn out faster than motors on Y-Delta or Solid-State Contactor starters.
There are three types of hydraulic elevator; holed hydraulic, holeless hydraulic and roped hydraulic.

The Hydraulic Elevator Controller, offered by us, features telemechanic contactors and on board optical isolation from field wiring. The car gate and landing gate voltage of Hydraulic Elevator Controller is 110v. In Hydraulic Elevator Controller, no additional terminals are required for shaft wiring as male-female connectors are provided on PCB itself. The Hydraulic Elevator Controller comes with LCD display for displaying shaft faults, car gate, landing gate, limit switches position, current position and destination of car, etc. Features
Simple and robust construction with telemechanic contactors.
Anti-creep input available.
On board optical isolation from field wiring
Car gate and landing gate voltage 110v
Single PCB, hence very easy to maintain and cost effective.
State-of-art design with Low voltage and High voltage separation in PCB layout.
Ideally no extra terminals required for shaft wiring as male-female connectors are provided on PCB itself, but shaft connectors of WAGO or PHOENIX can be provided at extra cost.
Down collective.
7 segment common anode display on board.
LCD display to show shaft faults, car gate landing gate limit switches position current position and destination of car, all pending calls, etc.
Single wire registration i.e. only one off wire from button.
Counting type car top reeds Only two reeds, one for up direction slowing and second for down direction slowing and two more reeds, one for up direction stopping and second for down direction stopping.
Counter for lift stopping after defined predetermined time, e.g. one day, one week, one month or two months, etc.
16 digit alphanumeric password for above counter.
Three stage safety chain for customer, avoiding accidental shorting of safeties by trainee technician.
There are six limit switches three on top floor and three on Ground floor. All limit switches are 110, for reliable intended operation. Reed switches are not allowed in place of limit switches, according to Bombay Lift rules.
All limit switches are NC according to Bombay Lift Rules.
Output contactor for motor, for isolating motor from source, according to Bombay Lift Rules.
Separate R-cam contactor fotr OTIS type locks.
As all components are of SMD technology, life of components increases because of reduced oxidation of contact and junctions.
As all electronics is only in one PCB, maintenance is reduced, call-back are minimised and easy to attend and diagnose the fault. Just replacing PCB solves all the problems.
Controller requires only few switchgear to complete the assembly, as all electronics is in one PCB only.
As all outputs are on the same PCB, no interconnection required between PCBs.
DOB, Auto Fan, Auto / Manual doors relays are also available on-board.
Floor setting is field settable.
