Drive motor that elevators the engine room via the control panel receives the command to act, and act in the desired direction cabinet works through. Cabinets, counter weight and friction between the drive pulley of the wire rope caused by a movement up and down moves. Is approximately equal weight to each car and counterweight. Reason is that energy savings have been. This type of propulsion machinery is called the friction-driven elevators. In addition to rope or chain wound on the drive pulley-operated lift is also available. From the way the elevators are called elevators the drum.
Elevators are broken down into types according to carrying capacity. Housing used in elevators, 100, 180, 240, 320, 400, 630, 1000 kg, 7, non-residential areas used lifts, 630, 800, 1000, 1200, 1600 kg to 5, health care facilities that are used in elevators, 1600, 2000, three species are separated to 2500 kg. According to the elevators, speed 0.63 m / sec, 1 m / sec, 1.6 m / sec, 2.5 m / sec and 2.5 m / sec speeds to 5 on the variety Of these, depending on the elevator cabin, engine room and the well is of changes in gap size. In addition, the elevators again, according to the speed and the engine brake system uses a variety of forces.
