HYDRAULIC ELEVATORS – Background, Specs, Types, Pros & Cons
Hydraulic elevators are one of the most popular multi-level structures in the world. They function to transport people and loads from one floor to another. These elevators have made transportation of equipment and people easier, and have allowed the disabled people to move between upper and lower floors.
Hydraulic elevators can work efficiently up to 5 or 6 floors. Piston-powered hydraulic elevators a have typical speed of around 150 ft. per minute. There are three main types of hydraulic elevators: roped, in-ground (roped), and hole-less. All hydraulic systems have four main components: a pump powered by electric motor, a tank (where the oil is stored), a cylinder, and a valve between the tank and cylinder. all hydraulic elevators require a pit below the elevator shaft. The weight carrying capacity of these elevators varies with size of the cab and typically ranges from 2000 pounds to 5000 pounds. Hydraulic elevators have low installation and maintenance costs Easy and quick installation These elevators do not require an overhead machine room These elevators have minimized hoist-way dimensions. Their machine rooms can be remotely located Hydraulic elevators can transport heavy loads Hydraulic elevators have limited performance and speed. The quality of their ride is lower than other types of elevators They require machine room for control components They are only suitable for low and mid-rise buildings Hydraulic elevators require high energy for functioning and are thus energy-inefficient.
