3.
Variation in level across the column mounting surface
. The surface that
the column is to be mounted to must be level. Measure the level with a
builder’s level across width and length directions of the installed column.
Options for customers concerned with column level:
o
Small variations can be managed with shims under the mounting bolts,
this is common approach.
o
Larger variations may require steel bars or plate to be used to bring up
the column to level.
o
Extreme variations will likely be best addressed with footings as
described in section 3.
4.
Height of enclosure
. Your shed should allow enough room for the top of the
hoist to clear the roof by 100mm when installing. This will allow for the removal
of the hoist after it is bolted to the floor (otherwise you will not be able to lift the
column off the mounting bolts).
5.
Confirm vehicle clearance.
Locate the position of the hoist intended for
installation. Draw a template on the ground with marking chalk and confirm the
height for clearance to the roof, and horizontal distance for clearance at each
end of the vehicle. Vehicles are lifted from the central point of gravity which is
typically around the middle of the driver’s door (between A and B pillars of
car). This will impact the clearance at the front and rear of the vehicle.
Measure the distance from the midpoint of the door to front and rear of floor
and confirm clearance at ground level and at maximum lift height.

6.
Confirm the maximum lift height clearance
for vehicle by measuring the
distance from the lift position to the ground. HAPP pads are typically around
110-120mm from ground level when in the lowered position. If your lift position
is 200mm then your total possible lift height will be higher by 80mm than
specified. This is not normally an issue however in some cases when you
have a high vehicle and a clear floor model you may need to allow for this. In
this case if you vehicle is a van with 2 meters in height for example, the clear
