12 BETA MAX PORTABLE HOIST SYSTEMS
TRESTLE MONORAIL
The universal mounting option system for all Beta Max portable hoists, the Trestle Monorail is ideal
for mounting on a flat roof or an intermediate floor. The system allows a 3.5 ft. cantilever. Two
people can assemble the system in minutes.
TRESTLE MONORAIL ANCHORING METHODS
Trestle Ceiling Brace: For use when the trestle will be installed on an intermediate floor of a build-
ing with a rigid structural ceiling above the trestle. The brace that locks the rear of the trestle
between the ceiling and the floor on which the system is mounted stabilize the trestle monorail.
After the trestle is assembled and placed in the desired location the jack is bolted to the top of the
inboard end of the monorail. The jack must be in firm contact with the ceiling structure.
Floor Tie Down Clamps: Most suitable for permanent applications. The clamps attach to the inboard
legs of the trestle and allow the system to be anchored by chains or wire rope.
Ballasting: A counterbalance system employing two rigid metal containers (each with a capacity of
9.5 cubic ft.) that are bolted to the inboard leg of the trestle. The weight of the material in the
ballast containers counterbalances the combined weight of the load and the hoist at the outboard
end of the trestle. Ballast material must conform to certain requirements. Bricks, solid concrete
blocks, stone or other high-density non-flowable materials are suggested.
Counterweighting: Uses counterweight clamps, which come complete with mounting hardware and
attach securely to the inboard legs of the trestle. This method lets you make use of flat steel coun-
terweights commonly used for roof outriggers. Standard 50 lb. counterweights slide down over the
27 in. upright.
Whatever anchoring method you use, additional tie back ropes should always be in place to secure
the system.
