Boulder Box (optional)
The boulder box is recommended in conditions where many large stones and
boulders are encountered and it is advisable to remove them from the field rather
than leave them in the trenches between the formed beds. The unit consists of two
rows of widely spaced 6 finger stars, and a single row of 10 finger stars. The 6 finger
stars allow normal material to fall through onto the cross web while large stones or
boulders are transported over the 10 finger stars into the boulder box. The boulder
box can then be emptied at a convenient point.
Cross Conveyor
Drive to the cross web is by means of two hydraulic motors, one at each end. In
order to place the conveyed material into the centre of the designated trench, the
speed of the cross web must be coordinated with the amount of traverse.
The LH side of the cross conveyor (item 1, fig 12) can be folded vertically to reduce
the width for transport and storage.
To unfold the cross conveyor:
1.
Remove the ‘R’ clip (item 2, fig 12) securing the transport lock top link (item 3,
fig 12) and allow it to hang freely.
2. Fully lower the conveyor end section using the switches on the control box.
To fold the cross conveyor:
1.
Move the conveyor fully to the LH side of the machine using the control box
‘Side Shift’ switch.
2. Fully raise the conveyor end section using the switches on the control box.
3. Refit the transport lock top link (item 3, fig 12) and secure with the ‘R’ clip
(item 2, fig 12).
