Continuous, infinitely adjustable moving up and down of the HaTe® tarpaulin by rolling/unrolling on an aluminium grooved tube. Distance and alignment variations during operation are accommodated by a mini-telescopic articulating coupling between the drive and the aluminium grooved tube. 

Wind loads on the HaTe® tarpaulin are carried by stretched HaTe® protection mesh.

The HaTe® tarpaulins are moved by stainless steel wire ropes and pulley blocks or by a central drive tube in combination with plastic rope drums and crown wheel gears (2 No.).  

Drive options manual (up to max. 50 m) or electric (up to max. 2 x 50 m).

Electric drive with sensors.  

Options:      

• Temperature (temperature sensor) and/or  
• Precipitation gauge (rain detector)  and/or
• Wind speed (air speed meter/cup anemometer) 

The HaTe® tarpaulin(s) are prevented from deviating out of alignment by guides consisting of high strength belts, screw eyes/lashing rings and ratchets.
