Very specific MODEL
Composed of : (to be studied on precise sketching)
– Main fixing articulated for tubular metallic frame
– Elevating fastening on pulleys
– 4 maintaining cables on each goal giving a really good stability and better loads sharing out + fastening for maintaining cable (ref.B3022) and fixings for cable on roof
– elevating wire made of 5mm galvanised steel (ref. B3016) + elevating fixings adjustable on frame (ref. B3021)
– set of pulleys made steel Ø100mm mounted on ball bearings + adapted fixings
– Tightening set (wire-strainer, clamps, links, fastening devices..)
It folds up to the roof and retracts itself in order to fit in between
2 roof timbers.
IMPORTANT: This is not always possible. Roof timbers must be spaced out enough and thick enough in order to place board and ring in between. Strengtheners must be useful because of the space in between roof timbers.
