Installation of Loft Blocks
Two types of Vortek loft blocks, multi-line
and single line (Figure 23), mount to the
I-beams using aluminum clamps as shown
in Figure 24.
1. Determine the center of each hoist (4.5"
from the edge of the hoist) and snap a
chalk line to the other side of the stage on
each beam position confirming that it is the
same location at the hoist center (Figure
25).
All multi-line loft blocks will mount on the
beams closest to the hoist. The single line
block will mount on the beam furthest
away.
2. Mount the loft blocks by aligning the
grooved drop sheave with the hoists’
centerline and tighten the beam clamps.
Repeat this process for all loft blocks
(Figure 26).
