Mounted permanently at roof level, a BMU is the safest and most complete form of suspended access system, providing full lateral, horizontal and vertical movement of the working platform.

These machines will normally have the ability to lift the cradle up and store the cradle in a suitable area on top of the building.

BMUs are produced in different sizes and weights providing hoisting heights of up to 400m and jib outreach up to 35m, enabling safe access to even the tallest and most complex building façades.

Optional window lifting with additional hoist is possible.

The machines can be designed to be hidden inside the building when not in use. Almost all highrise buildings (above 120 meter) in the world have such machines installed.
