The motorized undercarriage moves the roof car over a rail track, so that it is able to reach a large facade surface. A rail track can be customized according to the dimensions of the roof, and can possibly be used by multiple roof cars.
The Economical serie is equiped with a fixed jib. Depending on the BMU type the jib can be raised to bring the a cradle closer to the facade. For example a pantograph cradle can be positioned under a balcony by luffing the jib up. This function also enables a roof car to lift a cradle over a high parapet or roof edge.
A rotating spreader allows for adjustment of the direction of the cradle in relation to the facade. This makes it possible for workers to get close to curved facades or facade with a certain angle.
The PLC (Programmable Logic Controller) for our BMU’s is designed so that it can be monitored remotely. This facilitates remote inspection and analysis of system faults, and the integration of BMU data in a BMS (Building Management System).
The roof car can be rotated to change the direction of the jib in relation to the rail track. This function is used when the gondola is lifted from the roof and suspended over the edge. It could also be used to work around the corners of a facade.
All our roof cars can be equipped with a restraint system. This system connects the gondla to the facade, preventing that the gondola moves too far away from the facade, or starts swinging. This increases the safety of the BMU in windy conditions. A restraint system is for buildings that are 40 meters (131 feet) and above.
An industrial control panel which is used to control the power and movement of the roof car and jib. It includes buttons or switches that allow operators to control the building maintenance unit.
Extra façade rollers are deisgned for external use and can be used to provide insulation from the elements.
