Mechanical Lift refers to machinery that assists with lifting, moving of items and people. They are of various types; depending on the activity they are supposed to carry out. Some are fixed permanently on the buildings while others are not. They main function is to assist with lifting of moving of materials to higher heights. The first elevator is described in Greek History. Engineering in Kenya has more articles.
Importance of Mechanical Lift
The major function of lifts is to ease transportation and movement of components to very high heights that human beings cannot. By simply pressing a button, they move up. This eliminates the hassle for traversing the stairs or the ramps. A mechanical Lift is also referred to as an elevator.
This machine is involved in transporting people from one floor to another. The first elevator was discovered and described by Vitruvius, a Greek writer who described a contraption built by Archimedes. Elevators of antique period were operated manually by animals and human beings. They lasted up to the 18th century when the first mechanical lift powered by hydraulics was invented.
The importance of lifts is for those especially in the biomechanical industry. This is especially in nursing and in person care for elderly. This enables the elderly and the sick individuals to work with little or totally no dependence from the care provider.
It is also very common to find Mechanical Lift in the urban cities especially in the tall and several storey buildings. They are meant to minimize time wastage and energy by the workers when moving from one floor to another. In energy industry, especially in electricity, the lifts are used by the power companies to lift mechanics to higher heights when erecting electricity cables. Other sectors where mechanical lifts are used include the fire brigade, in architecture and in manufacturing and assembling industries.
How Mechanical Lift function
An example of these lifts is the Traction mechanical lifts. These are powered by motors. The motors use the rolling steel hoists over a drive sheath that hoists the cables. The gear box attached by a high motor is used. The lifts are powered by gearless motors, and the drive sheaths are directly attached to the motor.
Hydraulic elevators use controlled hydraulic and fluid power to raise or lower the lifts. These mechanical lifts are meant for medium and low rise buildings. In these lifts, the plunger presses down to generate power which moves up the elevator. The lifts descent is controlled via gradual release of the hydraulic pressure.
Hydraulic elevators have a smoother trip up and down. However, physical constraints have made these types of Mechanical Lift impractical for high-rise buildings.
Constructing Mechanical Lift
Lifts are of varying sizes which suit varying needs and are mostly found on a multi storey and fixed during construction. However, they can be added to buildings after construction if required. During this time, professional advice must be sought regarding the suitability for the building.
These include local government’s approval and compliance with their standards. Elevators range in models to fit the individual’s requirements. For example, mechanical lifts for commercial purposes will have different specification than those for non-residential purpose. The space available within the premises will also determine the type of elevator to be used.
Other determinants include lifting capacity, the height and width requirements within the lifts. The type of door arrangements required is also another determinant; whether it is a swing or sliding door. Other requirements are the capacity of the building, where it requires an internal mechanical lift or extended external to the building. How to get the materials is important to be considered. This includes whether the materials are to be obtained individually and then assembled on site and other installation processes that will be involved.
The number of floors the lift needs to travel, emergency operations in case of power failure, emergency stop buttons, powers and other requirements like power consumption are the other determining factors when constructing a Mechanical Lift.
