Es-service has designed the escalator step TK65 which also can be installed to any ET escalator. Starting from 2010 Es-service is supplying steps TK to the escalators ET for Helsinki metro (for today 10 escalators are already equipped with these steps). TK65 step has the series of advantages:

• Step has the lowest tolerance of the major dimensions. This is provided by the technology of production – instead of multi-positioning stamping Es-service use high-accuracy rolling;
• Step is assembled with high-quality new aluminum step-riser and combs;
• Step-riser is produced according to EN-115 with the edge tooth;
• Step core is produced from the metal 2mm width which prevents step core list from deformation in the places of casted details fixing and increase the life-time of the step itself;
• The unit of the main roller fixing is done repairable due to replaceable pin usage;
• The unit of the auxiliary roller is enforced to prevent appearance of the cracks and repairable due to replace ability of the auxiliary roller axis;
• Body and edge comb is connected through the lock on the whole length which prevents edge comb from swelling;
• Edge combs and body combs are fixed by the self-screws in special plastic dowels which prevents corruption;
• Step-riser is designed on the chord which prevents layer corruption.
