The problem

You keep paying for the same brake failure.

a.Energy-saving escalators stop and restart constantly. Each cycle mechanically engages a contact-type element that confirms brake release.
b.That contact wears with use — fastest on units that run continuously with frequent stop-start cycling, which is why it is the most common cause of brake unit failure.
c.Each time it goes, the solenoid brake unit is replaced — parts cost plus the call-out and labour that go with it, repeated over the life of the escalator.

The Bumdo solution

Sense the brake without touching it.

Our design confirms brake release with non-contact sensing instead of mechanical contact — nothing rubs, so nothing wears out.

Sensing

Non-contact detection

Non-contact sensing confirms the rod has reached its release position — with zero mechanical friction.

Install

Drop-in replacement

Designed to install on the existing brake arrangement of Schindler 9300 / 9500 / 9700 units — a parts swap, not a redesign.
