Physical installation
Warning! The Rotator 281 must be either fastened to a flat surface such as a floor or roof, or
clamped to a truss or similar structure. Do not apply power to the Rotator 281 if it is not
securely fastened.
Warning! The supporting surface must be hard and flat. Fasten the rotator securely.
Warning! Use only the supplied rigging clamps and M12 bolts. The clamp must be screwed into
the central holes in the rotator’s mounting brackets using the supplied M12 washers and M12
locking-nuts.
Fastening the rotator to a flat surface
The Rotator 281 can be fastened to flat surface such as a floor or roof. Check that the surface
can support at least 10 times the weight of all rotators and equipment to be installed on it.
Mounting the rotator on a truss
The Rotator 281 can be clamped to a truss or similar rigging structure.
When loading the rotator with full load it is important to use all 3 slim couplers when mounting.
To clamp a Rotator 281 to a truss:
1.
Check that the rigging clamp is undamaged and that the rigging
structure can support at least 10 times the combined weight of all
Rotators and equipment to be installed on it.
2.
Use the 3 supplied rigging clamp or contact Wahlberg Motion Design
for a replacement.
3.
Fasten the clamps to the rotator with the supplied M12 bolts, nuts,
and washers in the holes in the mounting brackets of the rotator.
4.
Block access under the work area. Working from a stable platform,
hang the rotator on the truss. Tighten the rigging clamp.
Mounting the rotator in an angle
The Rotator 281 can be mounted in any angle.
Warning! Always mount the load with the center of mass directly below the center of the axis.
Warning! The maximum load depends on the angle the rotator is mounted in. Refer to table
below

Shaft - down
150 kg.
(330 lbs.)
only with 3 rigging clamps mounted!
