Meeting OSHA & ANSI Powered Platform Requirements

Are you looking for an independent assessment of your building’s BMU or Powered Platform? We can help.

In addition to inspecting and testing roof anchors and davits, Wikstrom Engineering provides annual inspections of most types of building maintenance units (BMU) and powered platforms that are used for façade access. BMU and powered platform inspections ensure they are safe for use and that they meet OSHA 29 CFR 1910.66 and ANSI A120.1 requirements.

Wikstrom Engineering inspects all Building Maintenance Units including brands Manntech, Mannesmann, Tractel, and Cox Gomyl.

      Powered Platform Maintenance Inspections & Tests

      Understanding safety concerns and regulatory requirements for Building Maintenance Units (BMUs) and Powered Platforms when installed for use by façade access workers is key to ensuring safe building maintenance. Wikstrom Engineering is qualified to perform the annual inspection and safety assessment of these additional building maintenance elements.  

      While Wikstrom Engineering commonly performs the annual safety inspection according to OSHA 1910.66 which includes the secondary brake test, the maintenance inspection that is required 30 days before use and every 30 days during use should be performed by your maintenance service provider.
