Hydraulic Elevator
Hydraulic Principle
A hydraulic elevator up direction control system is provided that has a circulating valve connected between the supply and the return of a source that normally supplies pressure to the cylinder of an elevator. The circulating valve is controlled by a computer regulated stepless variable solenoid valve that influences the pilot fluid pressure in the operating chamber of the circulation valve to control the size of the opening of the circulating valve and thereby the volume of fluid passing through the circulating valve. This affects inversely the volume of fluid passing through a fluid flow measuring valve, to the cylinder, to provide selectably variable up speeds of travel facilitating a fast, smooth, accurate ride of the elevator car as it approaches a stopping point relative to an upper floor of a building.
Car Parking Elevator
These lifts are specially designed for the vertical transportation of a loaded vehicle or automobile with theirs drives making them extremely useful for:
- Private Garages
- Apartments
- Showrooms
- Service Station
- Complex
Rope Type Elevator
It is similar to a traction type elevator. The cab is elevated by an attached rope that is pilled by pistons.
Rope type 1 is a single indirectly acting suspension with wire ropes having one piston for regular loads.
Rope type 2 is an indirect suspension with wire ropes having dual pistons for heavy loads.

Rope Type 1
Rope Type 2
Hole Type Elevator
This type has a cylinder that extends into the ground the same height to which the elevator is to be lifted.
It is a directly suspension with a simple or a split piston. It is the simplest solution for any load.

Holeless Type Elevator
This type uses telescoping pistons in one or both sides of the cab to lift it. The cylinder stands within the hoist way and dose not required a drilled hole.
Type 1 is a single site direct suspension with a single simple piston for regular loads.
Type 2 is a double side direct suspension with dual simple pistons for heavy loads.
