Near dry machine system for escalator chains for handling

Near dry machine system for escalator chains for handling



Application Study of near dry machine DropsA system at:


Thyssen Krupp – Spain


Application:
Motor system for chains escalators (underground network - place of trial:Madrid and Barcelona)


Analysis of the lubrication system:
The existing system used brushes for lubrication that resultingtechnical problems as:  massive industrialwaste that get dirty the chain, low penetration of the lubricant, ineffectivelubrication, intensive maintenance.

 

Important Points of the system

Lubrication System DropsA
