Deployable Payload
A mast installation can be exposed to several types of loads. The physical weight of the instrument
and its attachments is referred to as the payload. The mast can support much more weight when
properly guyed and stabilized but BlueSky Masts will only recommend payloads that are safe to car-
ry during the deployment process and we call this the deployable load. The remaining reserve load
capacity represents the margin designed to absorb any subsequent environmental load that the
mast may encounter. The primary environmental load on a mast is wind load.
The payload capacity on a BlueSky Mast is governed by the installer’s ability to safely elevate the
payload to the desired height. As poles are inserted into the tripod and the mast begins to climb,
the mast tip has a tendency to lean off-center and away from its position of greatest strength. An
iterative process of incremental guying and mast pole elevation may be required to successfully de-
ploy the mast. For best results, please limit your deployment to the height and payload combina-
tions given in the table below.
