Car lift
Introduction
A lift is a load lifting device, a type of elevator, with mechanical, hydraulic or electrical technology, it is designed to raise or lower loads vertically, between different levels, without being intended for the transportation of people. It is used in industrial, commercial and domestic settings, and can take various forms depending on its specific function. Basically it is a platform or cabin that runs between two guides. It is often used in buildings under construction, warehouses and self-service stores. Its use requires certain knowledge and different governments require a permit or license to use it.[1].
Description
A forklift, also known as a freight elevator or goods elevator, is lifting equipment specifically designed for the vertical transportation of heavy materials and objects in commercial, industrial, logistics and institutional environments.
The forklift is intended for facilities that transport heavy loads in commercial, cultural or industrial environments. Reserved for staff, the cabins are usually spacious and the speed is slightly lower, with a transmission ratio that provides the engine with sufficient power. It is used, for example, to raise or lower pallets of products in supermarkets, as well as filing carts by librarians or beds and stretchers in hospitals, in addition to serving as an extension of the elevators available to the public.
As the forklift is a lifting system designed primarily to transport loads, its use is authorized only by the operator of the system alone or accompanied by other people. Simplified forklift designs have been developed as proposed by the industry. Forklifts installed in industrial buildings usually have access prohibited to the public and are authorized only to a restricted group of people trained in their use.
Electric forklift It is usually composed of an electric motor that pulls a cable. It can be with a counterweight and a friction-free pulley or the windlass type.
Hydraulic forklift Two enormous tanks shaped like an inverted bell, reminiscent of old gasholders, replace the engine. The hoods move very slowly, rising and falling a short distance, thanks to the powerful force generated by the fluid, sufficient to move the cabin and a large number of passengers at 2 m/s through a very high speed multiplication system. The elevator car moves thanks to a button that activates a piston containing oil. The oil is sent to a cylinder, which in turn drives the piston using a hydraulic power unit (pump). When the piston fills with oil, the cabin rises.
