The principle of escalator
The driving main engine is the power source of escalator, which transfers power to the spindle driving shaft through the main driving chain; the cascade chain is driven by the main driving shaft, which drives the cascade to move up or down; the tensioning device of the cascade chain installed at the lower part plays the role of tightening the cascade chain.
Structure of escalator
Escalator is a large and complex transportation equipment with mechanical structure as the main body. According to its functions, escalator can be divided into eight parts: support structure (truss), cascade system, guide rail system, handrail system, handrail device, safety protection device, electrical control system and automatic lubrication device.
