Inverted U Monorails | O’Brien Lifting Solutions

Inverted U Monorails provide independent, permanent fall arrest solutions over long spans in areas where there are no existing support structures. Foundation-mounted, reinforced W-Beam steel columns and arms support the SAFETRACK® monorail at heights of up to 28ft.

An Inverted U system comprises two steel columns connected at the top by a support beam from which a monorail is suspended. Typically, the monorail is suspended centrally along the beam. However, it can be offset to obtain the desired position while utilizing the most suitable column positions, which is ideal when working around existing obstructions. Inverted U systems are used across many industries where floor mounted systems are necessary.
