This step, which is a new design, is easy to fit, simple
to operate, combines rigidity with strength, yet is only
6¾ lbs in weight.
All the moving joints are made
with bolts and self-locking nuts, so that it is relatively
easy to free the linkage should it become seized through
neglect of lubrication. Except for the tread board, which
is wood covered with ribbed rubber and edged with aluminium,
the step is made of aluminium painted steel.
below the top of the mounting angles is 5¾ inches
and the fore and aft movement of the tread board is 7? inches.
"The Caravan" magazine, in their October 1964 issue, quote; "The
whole design is well thought out".
Materials required for fixing:
4 - ¼ inch diameter steel bolts of a length equal
to the thickness of the floor, plus thickness of any wood
battens, and plus ½ inch allowance for nuts.
4 - Large diameter washers (about 1½ inch diameter).
4 - ¼ inch diameter nuts
Wood battens to suit (if required)
On some caravans it will be possible to bolt the step
directly to the floor, but generally it will be mounted
with wood battens between the mounting angles and the floor.
The thickness of the battens will vary according to the
individual requirements of the owner and the limitations
of the caravan chassis or underfloor structure. Even if
the step is mounted below a chassis with 3 inch deep members,
the projection below the floor is only 7? inches.
Having decided on the longitudinal position of the step,
then place it upside down in the doorway, with the outer
edge of the tread board in line with the side of the caravan
and mark off the position of the fixing holes for drilling.
The wood battens, which should preferably run longitudinally
on the caravan and should not be less than 16 inches long,
should now be drilled at the same spacing as the holes
in the floor. ¼ inch diameter bolts with large steel
washers under the heads, can now be pushed down from inside
the caravan, and the battens and step threaded on from
the underside, then put on the nuts and tighten up.
It is now ready for use.
To operate, press up the outer edge of the tread board
and pull out, the springs will automatically locate and
lock it. Press up and push in to stow - again locking is
IMPORTANT - Keep the moving joints greased or oiled.
