Positioning the Adjustable Mounting Column
1.
When the crane is assembled, the Adjustable Mounting Column may be driven to it’s
full height. The column may either be hand cranked or driven with a 24V battery
driven screwdriver. We suggest you drive the screwdriver at speed 1. The connection
on the column is a 24mm, male hexagonal head.
Important: When adjusting the height of the column make sure that
the 4 Adjustable Stabilizing Rods can move freely and that
they are not restricted in travel. The Rod Locking Pin found
in the middle of each rod must be removed when adjusting
the height and reinserted only when the column is in the
required position.

Important: When driving the column upwards, do not go past the
“STOP” mark engraved on the column.
2.
When the column is in the required position, insert the 4 Rod Locking Pins into the
middle of each rod. Adjust the 4 rods until they are stiff, then counter lock with the
locking nuts found at end of each stabilizing rod (total of 8).
