The high cost of acquiring land and limited land space for building houses and offices in cities and highly industrious environments across the world has led to a paradigm shift from low level buildings to multi-story apartments and huge skyscrapers.
Accessing the various levels and segments in huge skyscrapers and multi-story apartments used for offices, schools, warehouses and residence is made possible by lifts (elevators). In the complete absence of elevators in such buildings, movement to- and -from each level of the building will be seemingly uncomfortable. The discomforts and risks associated with moving around these buildings without an elevator can slow down the pace of work, increase downtime and promote poor work culture.
For any corporate organization to adopt the use of elevators, it must first and foremost have a fair understanding about the different types of elevators and which one will be more suitable in easing movements and increasing efficiency.
Hydraulic elevators are carriage devices that are used for carrying and moving humans, luggage and other items from one level of multi-story buildings or skyscrapers to another. They can conveniently be categorized into two types;
Direct acting hydraulic elevators
Suspended hydraulic elevators
A Direct Acting Elevator is made up of a ram which slides in the internal of a fixed cylinder that has an opening at its bottom. The opening is the feature that permits the ram to easily slide in an upward and downward direction, and also allows hydraulic fluid to enter the cylinder. The ram of a direct acting elevator consists of a cage that is attached to its top. The cage serves as a big box that carries objects in both upward and downward directions. For movement in an upward direction, hydraulic fluid pressure acting from beneath the cylinder pushes the ram upward. In a downward movement however, the cage moves by allowing the oil in the cylinder to get drained into an accompanying oil reservoir.
A Suspended Hydraulic Elevator on the other hand, consists of a cage that is suspended from a wire cable, a jigger made up of a fixed cylinder, a sliding ram and a set of two pulley blocks that are placed at the bottom of the hole of the cage. Of the two pulley blocks, one is movable and the other is fixed. The available sliding ram of the elevator is connected to the movable pulley block. For moving and carrying objects, Suspended Hydraulic Elevators admits hydraulic fluid at high pressure into the fixed cylinder of the jigger. The hydraulic fluid forces the ram to move towards the left side which makes the distance between the fixed and movable pulleys to expand and as such moves the cage in an upward direction. The cage moves in a downward direction when the high pressured fluid in the cylinder is released.
