Innovative installation methods for Manntech’s facade access systems

Manntech is recognised globally for advanced German high quality engineered building maintenance units (BMU'S), having pioneered many of the facade access systems seen in the industry today. Manntech offers a variety of unique installation methods that are tailored to each project's demands, including both new installations and replacements of pre-existing building maintenance systems.

Manntech can help you navigate the pre-delivery and installation phases of installing a facade access system by providing an integrated project management experience. A project manager will conduct thorough preparation to ensure a smooth delivery process. Considerations for site access will be included in this preparation, such as organising traffic control and preparing the work area. This guarantees that the relevant individuals are on-site at the right time throughout the delivery, resulting in reduced material handling and safety risks.

Technical expertise can also be appointed to oversee challenging installations, such as a custom facade access solution designed to satisfy the needs of highly complex architectural buildings. Common methods of installation include:

Light Weight Roof Derrick Crane

An aluminium, lightweight roof derrick crane is an efficient and economical solution for providing access to install a building maintenance unit. With a maximum lifting capacity of up to six tones, derrick cranes require an installation time of approximately one week for the crane, after which a building maintenance unit can be installed in four to five days.

Mobile Crane

Ideal for low rise buildings, mobile cranes can also be utilised for the installation of building maintenance units. Installation of mobile cranes is efficient, requiring only one day, however careful planning is required to ensure that street closures, permits and reviews of nearby subway lines underground are considered.

Elevator or Hoist Cars

Installation’s utilising building elevators or hoist cars require the building maintenance unit to be broken into components due to varying capacity and size limitations. Detailed logistics planning is required for this method to ensure that pinch points and floor capacities are taken into consideration. Consequently, this method requires a longer installation time of one to three weeks and an extended commissioning period due to the separation of pieces.


Utilising a helicopter to install a building maintenance unit requires significant logistics planning, including of the staging area, flight path and required street closures. Likewise, the building on which delivery is being made needs to be secure and clean, with all personnel removed from the top three floors. As a result, this method is typically reserved for uncongested areas for BMUS with components weighing up to 16,000lbs and where the use of cranes isn’t an option.
