These instructions indicate step by step how you ensure a trouble-free installation and a satisfactory operation. It
is therefore of vital importance that you take the necessary time and care in order to ensure that the installation
tolerances are not exceeded, otherwise the hoist will not function effectively and you will not benefit fully from
your purchase of the hoist.
NB: Note this arrow → .The hoist will throughout these instructions be shown from the drive-on direction.
NB: If these installation instructions are not followed strictly, the hoist is not covered by warranty.

160mm. (HILTI HST3)
Information for fitter:
The hoist has to be installed on an even floor and must not be installed in or close to construction joints
(min. distance = 200 mm). The thickness of the wearing surface on the raw concrete and clinkers, if any, must
be added to the length of the expansion bolts.
Expansion bolts used for the installation of the hoist in not-cracked concrete:

NOTE: The requirements of the local authorities concerning installation of hoists must always be
respected.
AS/NZS 1418.9 Section 3.4 Location of Vehicle Hoists
Vehicle hoists should be positioned so that any moving part of the hoist or the load is not less than
600mm away from the nearest fixed structure. Where a vehicle hoist is installed adjacent to any other
equipment which moves, the minimum clearance between any part of the hoist or the load and that
equipment shall be 600mm.
15. Drill holes for 2 expansion bolts in each post (to ensure that posts do not tilt during installation). Drill ho-
les through base plate. Fasten posts by means of expansion bolts - do not tighten bolts yet as definitive
adjustment of post position will take place later on (see step 20).

20. Raise portal and place on posts.
Adjust distance between posts if necessary.
Fasten portal - adjust distance between portal members if necessary - tighten bolts.
21. Check distance between posts and that posts are plumb - shim up if necessary.
22. Drill holes through base plate for remaining expansion bolts. Tighten all expansion bolts.
Torque for expansion bolts: 110 Nm.
NOTE!
Shim up base plates so that posts are vertical. As much base plate surface should be in
contact with the floor as possible. Molnar recommends at least 75% surface/shim to floor
contact, specifically in the middle of the base plate which must be in contact with the floor or
shimmed.
