Technical Information

• The torsion springs that balance the weight of the door must comply with DIN17223, are

galvanized or painted. Spring usage alternatives with a standard life of 15 000 cycles, and
a life of 100 000 cycles can be used if desired.

• The steels of the torsion springs used in the doors have been specially sandblasted and

painted to extend their life.
• The steel ropes that ensure the healthy operation of the door are 6x19 = 114 wire wounds

around the polypropylene core and are resistant to 1960 N/m m² tension.

• The shafts on which the torsion springs of the door are attached are galvanized.

• Horizontal rails have rear connection C profile.

• There is a rope break safety system that prevents the door from falling down, as a standard

for the industrial system, in case the steel ropes break, and it is kept with a cover for
safety.

• The rails and brackets of the door are made of 2 mm galvanized sheet, depending on the

type of lifting (standard, low, high, vertical) application is made.
• There is a special lifting to prevent the rail profiles of the door from coming out of the

wheels.

• Rails and Angle profiles must be combined with air clamping without heat treatment and
have a structure that cannot be separated easily.

• The wheels that move in rails on the door sides are made of noise-preventing polyamide.

• As a standard, there is an opto laser safety system application inside the rubber gasket

under the door, which makes a soft touch and allows it to return upwards in case the door
encounters an obstacle during its downward movement.

• There is a special joint section that provides sealing between the door panels and a rubber

gasket throughout the panel integrated with the panels.

• There is a double lip rubber outer sealing gasket between the door panels and the top and
side walls, which maintains its lexibility down to -30º C.

• Between the door panels and the loor, there is a special hollow rubber gasket, which

provides sealing, ensures that the door is fully seated on the loor, and is inserted into the
profile on the bottom panel of the door.
