Langer + Laumann Smart Door Solutions

The Right Solution for Every Door

Whitesmith Solutions, in partnership with Langer + Laumann, supplies industry-leading elevator door modernisation solutions that restore reliability, improve performance, and extend the service life of existing elevator doors—without the cost and disruption of a complete door replacement.


Rather than replacing the entire door system, Langer + Laumann conversion packages upgrade only the door operator, motor, and control system, retaining the existing door panels and mechanical hardware wherever practical. The result is a faster, more economical modernisation that delivers the performance of a modern door operator while significantly reducing installation time, project costs, and lift downtime.


With more than 450 dedicated conversion packages covering virtually every major elevator manufacturer, Langer + Laumann offers one of the world's most comprehensive door operator upgrade programmes. Whether the existing equipment is obsolete, unreliable, or no longer supported by the OEM, there is almost always a compatible conversion solution available.


Why Choose Langer + Laumann?

For over 25 years, Langer + Laumann has specialised exclusively in elevator door technology, developing universal conversion packages that replace obsolete door operators while preserving the existing door system.


Unlike a complete door modernisation, which often requires extensive mechanical alterations and replacement of the entire door assembly, Langer + Laumann focuses on upgrading only the components most susceptible to wear and failure. This proven approach delivers a modern, high-performance door operator with substantially lower installation costs and minimal disruption to building operations.


Designed and manufactured in Germany, every conversion package includes purpose-designed mounting components, intelligent door control technology, and pre-engineered interfaces to simplify installation across hundreds of different door configurations.



The Right Solution for Virtually Every Elevator Door

One of the greatest strengths of the Langer + Laumann system is its compatibility.

With dedicated conversion packages developed for more than 450 elevator door systems, Whitesmith Solutions can supply upgrade solutions for virtually any existing installation, including both OEM and non-OEM equipment.


Supported applications include:


  • Centre-opening elevator doors
  • Side-opening elevator doors
  • Telescopic elevator doors
  • Car doors
  • Landing doors
  • Freight elevator doors
  • Obsolete and discontinued door operators
  • Legacy door drive systems
  • Manufacturer-specific and custom door installations


If the original door operator can no longer be sourced, a Langer + Laumann conversion package is often the most practical and cost-effective alternative.


Technical Assessment & Door Identification

Selecting the correct conversion package begins with identifying the existing door system.


Whitesmith Solutions provides comprehensive technical support, including door identification, compatibility assessments, and application engineering. In most cases, we can identify the correct conversion package using photographs of the door header, operator, motor, and door arrangement, together with confirmation of the opening type and clear opening width.


Our technical team works closely with Langer + Laumann to ensure every project is supplied with the correct conversion package for a straightforward installation.


A Smarter Alternative to Full Door Modernisation

Complete elevator door replacements are often unnecessary.


In many cases, the door panels, tracks, and mechanical hardware remain in good condition, while the door operator and control system have become obsolete or unreliable. Langer + Laumann modernisation packages replace only these critical components, providing the performance and reliability of a modern door system without the expense of replacing the complete assembly.


For building owners, consultants, and lift companies, this means:


  • Lower project costs
  • Shorter installation programmes
  • Reduced disruption to building occupants
  • Improved door performance and reliability
  • Continued support for previously obsolete equipment


Whitesmith Solutions combines local technical expertise with Langer + Laumann's world-renowned door operator technology to deliver practical, cost-effective elevator door modernisation solutions throughout New Zealand, Australia, and the South Pacific.
