STEEL GEAR RACK INSTALLATION
03. INSTALLATION
During the course of the gate, all elements of the rack must engage correctly with the pinion!
Spacers can not be welded to the rack!
Do not use grease or other lubricant too thick between rack and pinion as this may damage the automation!
Put the gate in the open position and unlock the motor
(page 7A).
1
Place spacers in all rack holes.
You should place them in the center of the oval rack holes, so you can fine-tune it at the end of the installation if necessary.
2
Position a piece of rack on top of the pinion and level it horizontally with a level.
3
Weld the spacer on top of the pinion.
4
Close the gate slightly until the other end of the rack stands on top of the pinion and weld the other spacer to the gate.
5
Close the gate slightly, letting the rack stay on the pinion and apply another piece of rack (A). To synchronize the teeth with the piece
already installed, use an additional piece of rack (B) and place it under the other two union, holding them with clamps (C).
6
Open the gate until the end of the new rack piece stands on the pinion and weld the spacer.
7
Remove the auxiliary rack piece and open the gate until the pinion is over the other rack end. Weld the spacer.
8
Repeat steps from 5 to 7 for each meter of rack you need to install.
9
Test the gate movement manually with all racks installed and weld the remaining spacers. If there is any friction between the pinion
and the rack, adjust the rack on the oval screws.
