Example 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.
