Yoke Box provides central emergency stop and tilt sensors. Platform locks onto mast in case over excessive tilt or slack rope condition. Mast guide rollers prevent sway and create a stable work platform. Secure anchoring to the façade every 20 ft. load capacity at heights of up to 330 ft. can be used simultaneously and independently from each other. No big trucks or forklifts are necessary. 1 phase 220V power is usually easier to find on job sites. ![]() Two workers can install and dismantle the complete system. The lightweight modular components are easy to store and transport. Use it as a mast climber, or add some roof rigging and use it as a suspended platform! No other system gives you this versatility! This means increased utilization and efficient fleet management.Ĭompanies that don’t yet own suspended scaffolding, now have a 2 for 1 platform system. Added safety is achieved by an automatic locking device that engages in case of excessive tilt or slack rope condition.Ĭompanies that already own Altrex suspended scaffolding can integrate existing hoists and platforms and need only add the mast components. Mast guide rollers keep the platform from swaying to create a solid work deck up to 50 ft between masts. ![]() The Fixeo system is lightweight and modular with a base of only 2-1/2 square ft and 5 ft high mast sections that only weigh 52 lbs! Two workers can transport and install the complete system. The Fixeo combines the advantages and takes away the disadvantages of each system to create a truly stable, efficient and cost effective way to access building facades during construction, restoration and maintenance. A suspended platform is lightweight, very modular and inexpensive, but it sways and roof rigging can be a problem. A mast climber is stable and ground rigged, but heavy, cumbersome to install and expensive.
