In general, all elevators are powered by electric power. In some elevators, hydraulic systems are used. Hydraulic elevators have long been used in factories and warehouses. Initially, water was used as a liquid and then oil was used. Rather, the hydraulic elevators, which are used to lift loads to places that are not too high, are also widely used to transport people after 1950s. The market share of hydraulic elevators in 1980s has reached 60 percent in America and 55 percent in Europe. In our country, it is not preferred.

Today, hydraulic elevators are used more often to lift large loads to low heights and generally in areas with roof problems. Such lifts can lift weights up to 4 tons. The operating system is based on the movement of the oil passing from the hydraulic unit to the piston in the pistons. The descent movement in these elevators is entirely with the car's own weight.

There are different piston types according to the dimensions and capacities of the elevators. The best thing about hydraulic elevators is that there is no encounter between the floor in the case of power cuts. It is equipped with a system that can put the load on the nearest floor.

Hydraulic elevators are used in villas, residences, renovated buildings, especially in the restoration works of historical buildings, in cases where additional load to the building statics is not desired, in theater and opera scenes and shopping centers for panoramic purposes.

Since hydraulic elevators carry people and cargo, regular checks should be made in terms of health and property safety. According to the current legal regulations, it is a legal obligation to be checked by authorized persons such as mechanical engineers, machine technicians and high technicians at least once a year.

our company Within the scope of elevator inspections, it performs regular inspections and inspections of electric and hydraulic elevators. During these activities, the Company complies with the relevant legal regulations and the standards published by domestic and foreign organizations. A few standards considered in this regard are:

• 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
