2.972 How an Elevator Works

The elevator is composed of a motor and, most commonly, a worm gear reducer system. A worm gear system is made up of a worm gear, typically called the worm, and a larger round gear, typically called the worm gear.

  • ConstructionOperationTechnologySafetyVariationsDefinitionUsesTraction elevators are the most common type of elevators. Elevator cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced by a counterweight since 1900. Sometimes two elevators are built so that their cars always move synchronously in opposite directions, and are each other's counterweight.worm machine, worm machine Suppliers and Manufacturers 44,076 worm machine products are offered for sale by suppliers on , of which speed reducers accounts for 18%, worm gears accounts for 4%, and paper processing machinery accounts for 1%.
