Building Maintenance Unit

Application of Building Maintenance Unit
Building maintenance units are used for the cleaning and maintenance of high building facades, glass curtain walls and window glass. They are also ideal choices for tall building curtain wall cleaning and maintenance as they allow users to get closer to the curtain wall than a suspended platform does.

BMU gondolas feature a higher safety factory, and are comprised of the hoisting machine, safety lock, wire winder (used to collect wire rope that is 100-150 meters high), upper limit device, lower limit device, hull and electric control box, and cable box.
