For affected single-plunger traction machines, there are two approaches to evaluate — and they have very different installation scopes.
Path A: Dual-Plunger Retrofit Kit. Adds mechanical redundancy at the brake assembly. Requires work on the machine itself, may require OEM coordination, and includes machine room access and downtime.
Path B: Rail-Gripping Safety Brake. HydraSafe mounts on the guide rail, outside the machine brake assembly. No machine modification, removal, or OEM coordination. Physical rail mounting is typically completed within six hours inside a permitted project.
Return-to-service timing depends on permitting, testing, and acceptance. Confirm the accepted approach with the NYC Department of Buildings (DOB) or your Authority Having Jurisdiction (AHJ).
