How does an elevator work?

There are two major elevator designs in common use today: hydraulic elevators and roped elevators. Hydraulic elevator systems lift a car using a fluid-driven piston mounted inside a cylinder. The most popular elevator design is the roped elevator. In roped elevators, the car is raised and lowered by traction steel ropes rather than pushed from below.
Elevators Explained
Today modern day elevators
consists of a hoist-way, platform, cab, doors, and a powered drive mechanism
used to provide lift and lowering. Elevators consist of door operators,
selectors, C.O.P's which is a car operating panel, inspection stations, safeties,
governors, valves, ect. All modern or newly installed elevators are
typically microprocessor controls.
Elevators are required to be in compliance with A.S.M.E. codes and
standards. A.S.M.E. also covers the installation, maintenance, and
inspection of elevators. Many new elevators today run on proprietary
computer based software that requires specialized tools for proper
maintenance & repairs that only the manufacture can provide. If your
building has proprietary equipment you will have limited maintenance service
options & generally have to pay higher premiums for maintenance. The use of non-proprietary equipment has become a large
part of the business because it allows the owner to offer the maintenance
contract to multiple contractors rather that just one; the manufacture.
Non-proprietary systems general cost more upfront but are offset by
allowing the owner to control the long term costs over the life of the
elevator. Traffic Flow is very important in today's society because as our
population expands our buildings keep getting higher & higher. Computer
controlled or microprocessor based elevators have an optimum flow of
traffic called "Dispatching". Dispatching cuts the time we stand in lobby
and wait for an elevator arrive. The way it basically works is the
dispatcher will register a call & find the nearest elevator going in the
directions the call was made & assigns that call to that elevator. Thus
providing shorter wait times.
Hydraulic Elevators
The cylinder is connected to a fluid-pumping system (typically, hydraulic systems use oil, but other incompressible fluids would also work). The hydraulic system has three parts: A tank (the fluid reservoir),
a pump powered by an electric motor, a valve between the cylinder and the reservoir. The pump forces fluid from the tank into a pipe leading to the cylinder. When the valve is opened, the pressurized fluid will take the path of least resistance and return to the fluid reservoir. But when the valve is closed, the pressurized fluid has nowhere to go except into the cylinder. As the fluid collects in the cylinder, it pushes the piston up, lifting the elevator car.When the car approaches the correct floor, the control system sends a signal to the electric motor to gradually shut off the pump. With the pump off, there is no more fluid flowing into the cylinder, but the fluid that is already in the cylinder cannot escape (it can't flow backward through the pump, and the valve is still closed). The piston rests on the fluid, and the car stays where it is. To lower the car, the elevator control system sends a signal to the valve. The valve is operated electrically by a basic solenoid switch. When the solenoid opens the valve, the fluid that has collected in the cylinder can flow out into the fluid reservoir. The weight of the car and the cargo pushes down on the piston, which drives the fluid into the reservoir. The car gradually descends. To stop the car at a lower floor, the control system closes the valve again.
Cable Elevators
The ropes are attached to the elevator car, and looped around a sheave. A sheave is just a pulley with a grooves around the circumference. The sheave grips the hoist ropes, so when you rotate the sheave, the ropes move too. The sheave is connected to an electric motor. When the motor turns one way, the sheave raises the elevator; when the motor turns the other way, the sheave lowers the elevator. In gearless elevators, the motor rotates the sheaves directly. In geared elevators, the motor turns a gear train that rotates the sheave. Typically, the sheave, the motor and the control system are all housed in a machine room above the elevator shaft. The ropes that lift the car are also connected to a counterweight, which hangs on the other side of the sheave. The counterweight weighs about the same as the car filled to 40-percent capacity. In other words, when the car is 40 percent full (an average amount), the counterweight and the car are perfectly balanced. The purpose of this balance is to conserve energy. With equal loads on each side of the sheave, it only takes a little bit of force to tip the balance one way or the other. Basically, the motor only has to overcome friction -- the weight on the other side does most of the work. To put it another way, the balance maintains a near constant potential energy level in the system as a whole. Using up the potential energy in the elevator car (letting it descend to the ground) builds up the potential energy in the weight (the weight rises to the top of the shaft). The same thing happens in reverse when the elevator goes up. The system is just like a see-saw that has an equally heavy kid on each end. Both the elevator car and the counterweight ride on guide rails along the sides of the elevator shaft. The rails keep the car and counterweight from swaying back and forth, and they also work with the safety system to stop the car in an emergency. Roped elevators are much more versatile than hydraulic elevators, as well as more efficient. Typically, they also have more safety systems.
