Side Mounting Brackets
For mounting masts to vertical surfaces of vehicles or buildings. Comprising two aluminium alloy castings, giving full protection to the mast tube, bolted to galvanised steel bars formed to give a distance of 260mm. between the centre of the mast and the mounting face. (Hole centres are 460mm. apart for M 12 bolts). These brackets are not designed to support the weight of the mast which should stand on its base.
Electric Winch
This electric winch is driven by a robust 12v DC motor with limit switches set to automatically operate at the desired minimum and maximum mast heights. When connected to a standard 12v vehicle battery it takes approx 6 mins to fully extend the tallest mast in the series.
There is a two button control for up/down operation, which stops when the button is released. This winch can also be operated manually with the handle provided, in the event of a power failure. The spooled drum prevents the wire rope from bunching and ensures smooth and controlled operation. The winch is weather protected to Standard IP54
