An elevator door operator is the drive that opens and closes the car door and landing doors on every single trip — the most cycle-intensive door application in any building. The niche demands precise, adjustable speed and force control across the whole travel profile: fast approach, slow-down before contact, and a defined closing-force limit so the leaf never traps a passenger. Industry practice for this class is a VVVF (variable-voltage variable-frequency) drive with closed-loop position control [ESTIMATE]. Note the standards boundary: EN 12453 explicitly excludes lift doors from its scope [SOURCED: antpedia.com], so whole-lift conformity to EN 81 / ASME A17 remains the lift integrator’s responsibility — RAX supplies the door-operator mechanism engineered to your interface [ESTIMATE].
RAX Door Technology manufactures elevator door operators on an in-house servo motor assembly line, validated in a 100,000-cycle fatigue test lab. Servo / VFD drive capability delivers smooth acceleration and deceleration ramps, with anti-pinch protection and safety-edge inputs, and WiFi / RS485 connectivity for integration with your lift controller. As a pure manufacturer (no on-site installation), we match travel, speed and force to your door geometry, then ship from a single sample unit — full flexibility on order quantity — with wiring diagrams and English manuals under full OEM/ODM terms.
Servo / VFD drive with programmable speed and force ramps for smooth, quiet door travel and a controlled, safe closing phase — precision servo-drive manufacturing is our core competency.
Every design is validated in our in-house 100,000-cycle fatigue test lab — the right discipline for an application that cycles hundreds of times per day.
Anti-pinch protection, safety-edge / light-curtain inputs and force limits engineered to EN 12453 practice for powered doors [ESTIMATE].
WiFi / RS485 connectivity and dry-contact logic for mating with your lift controller; technical drawings and wiring diagrams ship with every order.

Figures marked [ESTIMATE] are industry-typical conventions for elevator door drives, not RAX test data; RAX’s own speed/force/voltage datasheets are confirmed per inquiry. RAX figures are from the approved brand brief.
Door type (single-speed / bi-parting), clear opening width × height, leaf weight and travel — the basis for the speed and force profile we program.
Trips per day, temperature range (RAX products are tested from −30 °C cold storage to +50 °C desert conditions), machine-room or in-hoistway mounting.
Your controller’s supply voltage (24 V DC or AC), signal logic (dry contact / bus), and any WiFi / RS485 integration requirement.
Required closing-force limit, safety-edge or light-curtain inputs, and the certification route your lift integrator follows (EN 81 / ASME A17).
RAX supports full private-label production of elevator door operators: custom colors, operator matching to your car-door line, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA (27-year zero-leak record). Standard lead time 12–20 days per container; FOB Tianjin / Qingdao, FCL & LCL supported.
Product standard for industrial, commercial and garage doors and gates — the harmonized basis for CE marking of RAX door systems.
Safety in use of power-operated doors — force and entrapment-protection practice. Its formal scope excludes lift doors, which sit under lift rules [SOURCED: antpedia.com].
Lift-construction standards governing the complete elevator; conformity of the installed lift is the integrator’s scope — we engineer the operator to your interface [ESTIMATE].
Design and testing of protective devices (safety edges, light curtains) and mechanical test methods referenced across the door-operator framework.
Industry practice for this class is a VVVF (variable-voltage variable-frequency) drive with closed-loop control, which gives the smooth acceleration, slow-down and controlled closing force that passenger service requires [ESTIMATE]. RAX builds on its own servo / VFD drive technology, programmed to your door’s travel and weight profile.
EN 12453’s formal scope excludes lift doors [SOURCED: antpedia.com]. RAX holds CE to EN 13241 and EN 12453 for its door-operator range and applies the same force and entrapment-protection discipline, but conformity of the complete installed lift to EN 81 / ASME A17 remains the lift integrator’s responsibility.
Yes. We build dry-contact and bus interfaces plus WiFi / RS485 connectivity options, and we match supply voltage (24 V DC or AC) to your controller. Send your controller I/O list and we confirm the interface on technical drawing.
The operator supports adjustable closing-force limits with anti-pinch protection and safety-edge / light-curtain inputs, aligned to EN 12453 / EN 12978 practice for powered doors [ESTIMATE]. The exact safety architecture is confirmed with your lift integrator per project.
Yes. Color, operator matching to your car-door line, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production, under NDA with tooling archived up to 5 years.
Sample 7–15 days; standard container 12–20 days; custom first order 20–35 days (repeat 15–20). Operator/motor warranty is 3 years (servo motor 5 years), with free spare parts dispatched by DHL/FedEx within warranty (5–7 days).
