EC 203 escalator machine replacement
1. The applicable escalator refurbishment task
Package EC203-mod-01 is for 510 public escalator overhaul to replace drive machine type EC 203 which was a developed in the 1980s and discontinued in the late 1990s. Conduct this package is to use a modern substitute machine for replacement.
2. Technical solution
The existing latest design machine with its footprint the same as the original EC 203 size is not available in the market. In other words, there is no machine that can be one to one replace the EC 203 machine simply. Our technical solution is to design an adapter plate for new machine supporting and fix the plate on the truss support beam.
The substitute machine is qualified by certificate body and meeting code EN115 requirement. The method of machine fixation with adapter plate is verified by calculation and the safety factor is bigger than 5.

|2||Helical geabox machine||IE2 / IE3||
We provide two different types of gearbox used for driving machine replacement. The first is the worm gearbox machine and the alternative type is high efficiency helical gearbox from OMS company from Germany. The machine motor is made in China and the motor energy efficiency level IE2 is standard configuration and IE3 as an option. Due to the different reduction ratio of the gearbox, for the teeth number of sprocket on the new machine output shaft, our engineer will figure out for the customer based on the data in the original escalator so that the escalator operating speed will keep running at 0.5m/s.
Optional features of machine
|Motor thermal protection switch|
|Handwheel safety contact|
|Brake lift monitoring device|
|Indoor / outdoor application|
|Protection class IP44/IP54|
|Variable frequency drive support|
|Brake lining wear device|
|Over speed device|
|Non reversal device|
The machine dismantles and installation by using the following tools:
• Standard service tool (hammer, screwdrivers, wrench set)
• Magnetic drill
• Gantry hanger
Use a gantry fixture to lift out the original machine and load the new machine into the machine room. The installation process is simple and efficient.
The aged escalator drive machine replacement is possible.
