Driveway layout
Layout, like gate mounting, can minimise extra
safety devices without compromising safety.
Sets contain one photobeam, normally wired to
the re-open
[F]
input. The beam is fixed to the
gate pier or post. A second pause photobeam on
[E]
input is placed outside the swing of the gate.
The entrance should be on level ground from
pier to pier. The casements need to be at
finished ground level. It is possible to have
casements at different heights but one leaf will
need to be adjusted to suit.
Casements need functioning drainage. In most
cases, the drive will be higher than the water
table, so a soakaway may be sufficient. Steep
private drives may have regular run offs towards
the road that will frequently fill the casement,
then fill the soakaway. Consider a surface drain.
Wood swells when it absorbs moisture. A gap
between gate boards and between gate leaves is
essential. Any sight gap between leaves can be
covered by a rebate on one leaf. This will dictate
the order that the leaves open and close. This
control panel function is also used for drives that
curve inside the property.
On a few occasions, the driveway may be so
steep that it is necessary for gates to open
outwards. This is to be discouraged as it puts the
public at more risk.
Similarly, the casement should be level on both
axes, pitch & roll. However, to adjust roll angle X
can compensate for a steep drive. This needs
careful calculation that can be viewed on our
webpages.
The return wall on the left, or any other fixed
solid feature, should be over 0.5m the area
swept by the gate. Any closer, and a protection
device may be required.
