Permanent Platforms - Building Maintenance Units (BMU)

Building Maintenance Units (BMU)

Our permanent suspended platforms or Buildings Maintenance Units (BMU) are combined with roof cars, monorails or davits, providing safe, reliable and simple access solutions for window cleaning and external building maintenance. Also known as Window Washing Gondolas in Asia, Power Climber's permanent platforms have become the industry 'standard' for BMUs and are purchased by building maintenance system manufacturers and installers worldwide. Our BMUs meet or exceed the special requirements set by European Standard EN1808 for permanently installed building maintenance units.

Features:

  • Powered either by PC400 or Astro hoist
  • Motorized wire winders to store steel wire ropes (suspension and safety ropes) with up to 200 m capacity
  • Cable bin to store electrical supply cable
  • Protective cladding against falling objects (compulsory for EN1808)
  • Bottom limit trip bar
  • Top limit and ultimate top limit switch
  • Electrical interlocks on safety devices
  • Low voltage controls (compulsory for EN1808)
  • Automatic self-leveling system
