The AW Contractor Hydraulic Tailboard has lifting arms which are located on the
outside of the trailer. This enables the tailboard to be easily used in conjunction
with a variety of optional extras such as extension sides, silage sides and side
to side roll-over sheets. This type of tailboard also gives a high clearance.
The tailboard mechanism incorporates a slotted profile which pivots on 45mm diameter
chrome pins which can be easily greased. The slotted profile enables the tailboard
to initially lift vertically out of the 4 profiled lugs welded onto the trailer rear
cross member and then pivot to open fully.
The double acting hydraulic rams are fitted with hydraulic check valves to prevent
‘creeping’ of the rams during travelling and to ensure that the tailboard opens evenly.
The combination of the check valves and the profiled lugs on the rear cross member
maintains a good seal at all times.
The rams are chrome plated and fitted with rose joints at both ends.
The mounting of the tailboard ram base is kept to a minimum and is tapered and
shaped to prevent snagging. The box section ‘A’ frame arms are set to as close to
the bottom of the tailboard as possible for strength. The tailboard itself is fixed
by 4 heavy duty fully adjustable bolts making adjustment simple and thereby enabling
a good seal to be maintained.
