Roped (traction) elevators came first. Otis Elevator Company invented the modern elevator in 1853 which used ropes. Otis Elevator Company then also invented the first hydraulic elevator which was installed in 1909 at the Singer Building in New York City (since demolished).
Elevator auto-homing sends the elevator to a predetermined floor when not in use. This is usually the first floor. Hydraulic jacks and cables raises and lowers the elevator cars.
the Otis-dominated elevator industry kept pace with developments of its own, introducing the hydraulic elevator in 1878, the electric elevator in 1889, and the gearless traction electric elevator in 1903.
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
Schindler is a company that is known for building hydraulic elevators. They are very highly rated.
An elevator pit typically contains the elevator buffer, which absorbs energy in case of a sudden stop or free fall, the counterweights, and the guide rails that ensure the elevator cab moves smoothly. Additionally, it may also house the hydraulic equipment or motor that powers the elevator.
The main forces acting on an elevator are gravity, which pulls it downwards, and the tension in the cables or hydraulic system, which lifts it up. Additionally, there may be air resistance and friction that affect the motion of the elevator.
