BBJ Big foot condensing unit support platform frame Frameworks  for 4 standard units 2m x 1.2m

Spreads the weight of the supported plant
No penetration of the waterproof membrane, eliminating any difficult detailing, therefore reducing the risk of leaks
Cost effective
Complete on-site flexibility both during and after installation
Flatpack system for easy transport
Hot dipped galvanised metalwork
Eliminates the risk to roof guarantee
Re-roofing
The big foot system legs may be removed individually for re-roofing or refurbishment, without decommissioning or removing the equipment.

Height adjustment
Over 100mm of vertical height adjustment, to take up variations in the roof (300mm stepped roof option). Floor to framework: 245mm - 350mm

Condenser clamps
The repositionable clamps locate on both sides of the cross-bars, locking down onto the feet of the condenser units as they are tightened.

Linear adjustment
The cross-bars which support the condenser
Units can slide along the plain bars into the position required, then are locked securely in place.

Leg & bracket positioning
The leg & bracket are usually positioned outside the framework, but can be positioned inside if there is an obstruction.

Custom frameworks

With a plan of your roof and dimensions / weights of the plant, we can specify complete big foot frameworks to support up to 10 tons. The system is completely flexible - we can change any part of the design of the frame at any time! We can increase or reduce the weight loading (kn/m2) by changing the number of leg assemblies on the frame.

The big foot mouldings are made of glass filled nylon with uv protection. An independent anti-vibration mat is provided for each foot. All metalwork is hot dip galvanised for all weather protection.

Our system allows for each leg assembly to be removed individually whilst the roof surface is maintained or even re-roofed without the need to decommission and removal of equipment.

Big foot systems set the standard of installation on site, providing the consultant with a method of installation which is quick, clean, practical and aesthetically pleasing.

Modular frameworks

There are three basic modular frameworks available in 1m, 2m and 3m versions. For flexibility, all leg assemblies and cross-bars on the modular frameworks slide up and down to the required location.

The modular frameworks come with 305mm2 feet which are provided with anti-vibration mats to fit underneath. The frame is constructed from 40mm x 40mm standard box section. For heavier loads larger 450mm2 feet are available and heavy duty 50mm x 50mm box section for some components.
