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

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

- Elimination of monthly monitoring by the operator 's
- Elimination of the problems caused by the chain jumping on the teeth ofthe 'gear
- Reservoir Load Range 4 months
- Preliminary study demonstrates an increase of chain life of 25%
- The quantity of lubricant used is reduced by 80%
- Number of cycles per day: 19.5
- Oil worn out per cycle:  1.28 cc
- Oil worn out per day:  24.96 cc
- Oil worn out per month: 0,77 L compared to 5 liters consumed with the old system


This case application was implemented using
