Fixing the Motor’s Anchor Plate to the Pillar
Fixing the anchor plate to the pillar is critical to how far the articulated arm will reach the gate. As we have
seen in the previous section, the further away the motor is from the edge of the pillar, the less reach the
articulated arm will have - consequently the degree angle of opening will be less.
Dimensions of Anchor Bracket:
Once the fixing point for the anchor plate has been established, the plate must be fixed securely to your pillar.
There are two approaches to this:
Bolting - Use 12mm diameter bolts (M12) paying attention to the length of thread
required to securely anchor the motor’s plate to your pillar.
(Not supplied with kit)
Spot Welding - If you are welding the anchor plate to a metal pillar / post or a metal plate
that is bolted to a wooden pillar, shave off the galvanised coating on the
chosen area of the motor’s anchor plate prior to welding. This enables the
weld to grab efficiently for long lasting use.
The anchor plate is fabricated from 5mm thick galvanised mild steel. Due to the manufacturing process, the
anchor plate can be positioned on your pillar in one of two ways:
Fig. H – This is a typical plate alignment on a pillar. With the L shape
platform in a lower position to which the motor is resting on and
secured in place with its own anchor bolts. In this arrangement, the
anchor plate bolts are ‘carrying’ the weight of the motor.
Fig. I – This bracket alignment on the pillar, with the L shape platform
in a higher position, will ‘support’ the weight of the motor.
There is no structural benefit to this arrangement, only aesthetic. The
motor will be visibly seen sitting proud on a ‘shelf’.
Once the anchor plate is positioned and strongly fixed to your pillar, next we look to anchor the Kit Simply
motor to the bracket.
