Gantry type “light duty” and “heavy duty” are available. The gantries can have many different designs. They are available fixed length or extendable. The gantries can be installed suspended from or rolling on Aluminum Alloy or H Beam tracks. They can also be suspended from a pivot point in the centre and a circular track on the other side or otherwise to suit the specific building. Sometimes the gantries are equipped with monorail tracks underneath, allowing a suspended platform to access the whole area beneath the gantry. This is typical for internal atriums giving access to not only the glass roof, but also lamps, sensors, fire protection etc. which has to be inspected and replaced from time to time. Most traversing gantries are special design. All gantries can be delivered with compact aluminum flooring; providing excellent “non-slippery” surface. Both powder coated finish and natural anodized finish are available.
