4.1
ASSEMBLY OF THE 4’ SKYBEAM
®
The SKYBEAM must be pre-assembled in accordance with
these instructions. The counterweights are assembled on the
counterweight Frame and all roof loads must be confirmed in
accordance with this manual.
When using casters, install guide channels on structure to guide
the casters. Two channels are required, one for the front
support and one for the rear counterweight Frame. See Fig. 1.
• Block the end of guide channels with end stops.
• Always use a guide channel on roofs to distribute bearing
load.
• Guide channels to run parallel to building face.
• Rigidly secure both ends of guide channels to the structure
Determine if you are using the two or three beam version of the
4’ Skybeam. Both have a 4’ reach and a 1,000lb (454 kg)
capacity, the advantage of the three piece beam is less
counterweights are required (16) versus (28) required for the
two beam variation.
