The first elevators were mostly produced for load carrying. The first examples of freight elevators were used when moving coal and mines extracted from mines in the nineteenth century, and later when materials were transported in factories. Generally, these first freight elevators were powered by steam power. The first elevator samples used in human transportation today were designed by the American inventor Otis, who developed safe braking systems. The elevators used today are produced at high quality in terms of safety conditions. In these elevators, there are many security systems such as overload warning system, shock absorber system in case of sudden falls, motorized braking system, parachute braking system, double control system inside the cabins. Even in ancient times, people used the machines to lift heavy loads. Roman architect Vitarius' BC. According to the work he wrote in 26, 236 years ago, some machines were used to lift loads in Rome. Likewise, in the palaces of the Roman Emperors, there were structures similar to closets.
In workplaces or dwellings, the safety of people comes first, followed by property safety in any way. Therefore, all elevators, people and the safety of the load should not jeopardize. The legal obligation in this respect is the Occupational Health and Safety Law issued by the Ministry of Labor and Social Security and the Regulation on Health and Safety Conditions in the Use of Work Equipment. This regulation contains the conditions to be followed for the safe and healthy use of load and human lifts. Electric elevators are pull elevators with up and down cabin driven by the electric motor with the grooved wheel or the rotation mechanism at the top of the elevator shaft.
The pivoting mechanism is connected to the turning shaft of the motor. The steel cables extend from the ceiling of the car to the top of the elevator shaft, overhanging the pivoting mechanism there, again down the elevator shaft and reaching the stabilizing weight. The motor thus lifts only part of the load (approx. 40%). Hydraulic elevators, on the other hand, carry the weight and load of the car in a lift downwardly in a vertical cylinder. The roller must extend to a depth equal to the height at which the elevator escapes inside the building. Therefore, hydraulic elevators are not installed in multi-storey buildings. The cabins of the elevators carrying people are larger and superficial than the others, and the entrances are wider for people to enter and exit quickly at every stop. The length, width and depth of the other elevators vary according to their intended use. For example, hospitals have several elevators with at least deep, narrow cabins for transporting floor-to-floor devices, stretchers and wheelchairs.
Inspection and inspection of elevators used in factories, shipyards, harbors, railways and many other establishments, not only in residences, workplaces and construction sites, should be performed at least once a year by authorized persons such as mechanical engineers, machine technicians or technicians. The electrical parts of the elevators should be checked by the authorized persons. Human elevators are the elevators used inside and outside the high-rise buildings. Elevators capable of carrying up to 1 tons can reach up to an average 1.5 m / s. Human lifts 20-25 can carry loads up to one person. Safety and comfort are most important in human elevators. The interior of the cabin can be coated with wood, metal or glass. In today's technology, doors now open and close automatically. Modern human elevators, which are very good in terms of visuality, are subject to elevator regulations. Human lifts must be controlled by accredited companies according to the regulations.
Our company performs cargo and human lift control and inspection services in accordance with the relevant legal regulations and standards published by domestic and foreign organizations. A few standards considered in these studies are:
- TS EN ISO 14798 Lifts, escalators and escalators - Risk assessment and risk reduction
- TS EN 81-3 + A1 Lifts - Safety regulations for construction and assembly - Part 3: Electrical and hydraulic service lifts
- TS EN 81-20 Safety rules for the construction and installation of elevators - Elevators for the transport of persons and goods - Part 20: Elevators of persons and goods
- TS EN 13015 + A1 Maintenance of lifts and escalators - Rules for maintenance instructions
