Driver (in chain-example): driven mainly by a motor, worm gear, sprocket, brakes (brake) and other components. On the installation position of the motor can be divided into vertical and horizontal, vertical escalator currently used mostly driven machine. Its advantages are: compact, small footprint, light weight, ease of maintenance; low noise, vibration small, escalators, particularly monolithic driver (Figure 6.3), its motor rotor shaft coaxially with the worm, thus well-balanced, and can eliminate vibration and reduce noise; large carrying capacity, small lift height of the escalator by a drive motor drives, the lift height of the escalator driven by two drives. Texas Noah Witt escalator is the core component two chains, which circulates around two pairs of gears turning. At the top of the escalator, with a motor drive gear to rotate the chain ring. A typical escalator uses 100-horsepower engine to rotate the gear. Engine and chain systems are installed in the truss, escalators customized framework refers to the metal structure extending between two floors. The conveyor belt moving a plane different price escalator, chain ring movement is a set of stairs. Escalators most interesting places are moves these steps. When the chain moves Zhanhua escalator, stairs remained level. At the top and bottom of the escalator, stairs folding each other to form a platform. Thus the upper and lower escalator easier.
