Aluminum Screwlift Control Doors
Aluminium Screwlift Doors are custom made to suit any opening size.
They are ideal for bankless channel developments and can be used on the offtake, infield and outfall structures. They are perfectly suited for automation because the actuator is simply bolted to the bottom of the door and to the headstock.
Manual control of the door is done by a gearbox fitted to the yellow headstock using a 32 diameter stainless steel thread.
A watertight seal is achieved with using neoprene guide and sill rubbers.
Screwlift doors can be mounted on control pits, headwalls, bankless checks, drive over weirs and supply channel checks.
