506 Escalaire/Escalator Rebuilds
506 Escalaire Complete Unit Assembly View
Otis 506 units, known for their glass balustrades, differ from 506SL units, so parts aren't interchangeable. For compatibility, consult your UNITEC representative. Key features include two belt-driven handrail drives at the top, powered by a separate chain. As EC143 or 16VEC-RH machines exceed their service life, UNITEC offers the EC2-7 Service Replacement Machine for reliability.

The Electrical Safety Device Identification Guide - 506
This chart outlines the safety switches and devices used in 506-Escalaires, matching the electrical designations on your unit's wiring diagrams. Review your diagram and unit features to identify specific switches, as not all 506 units include functions like brake lifting or wear switches. Use this chart to verify components for replacement or modification.
Use this informative flyer when discussing 506-Escalaire rebuild proposals with building managers. Leave a copy with your customer to clarify key components for overhaul as ~1990s equipment ages. Highlight critical areas needing attention, like worn track sections in landing and turnaround areas. Over time, mechanical systems endure loads and incidents affecting performance, often unseen without inspection. Evaluate these components in your rebuild quote, even as optional additions. We're here to support you for a successful rebuild.
