Maximum anti-crushing safety thanks to the sensitive edges (optional) combined with maximum pressure relief valves that limit the maximum value of the hydraulic pressure in the presence of obstacles (adjustable during installation).
Ideal for heavy workloads in the presence of large-sized up-and-over doors.
Locks on opening and closing (double lock) the door
remains shut without installing further locks
AT 50 can be easily installed without modifying the upand-over
Very high resistance to shocks and stress during operation
thanks to the ductile cast iron body.
Great hydraulic sealing thanks to internal scrapers.
Silent and regular performance guaranteed by polyurethane seals and P.T:E. guide rings.
