2.2.5. Positioning Posts For Gates Opening To A Secondary Position.
For the set
-
up for gates closing in two
positions refer to Fig 6 (to right) for
calculating post positions. Start by
determining the primary working as the
secondary working is driven by these
figures. This most complex scenario
traditionally occurs for gates located
along a scrape passage (for example) with
gates swinging out from the bedded area
to the feedline.
In a scrape passage arrangement the
primary working clear gap dimension (y) is
driven by the passage width/gable set
-
up.
Refer to Fig 6a (below) when hanging
from an RSJ at the gable ends.
Note:
post faces along the scrape line are
aligned regardless of post size to give a
consistent scrape edge.

2.2.4. Gate Set
-
Up Slamming To Wall.
It is common to feature some type of receiver in this arrangement, typically a slotted plate receiver
is bolted to or welded to the wall or stanchion face, in this instance add the depth of the receiver
to the clear gap dimension (y) to allow for sufficient clearance.
