The belt block is fastened to the back of the car with two captive screws
(Figure 2-3). Make a careful note of the orientation of the block with respect to
the car.
Orienting the Parts During Assembly
To determine the orientation of an extension section examine the flanges on
the edges of the section and note that they are dissimilar. Position the section
so that its orientation matches that of the elevator base.
Figure 2-4 shows a typical mechanism assembly. The motor drive section
always goes on top, and the base section with the idler pulley always goes on
the bottom. Extension sections are mounted between the motor drive section
and the base section. All sections are joined together with tie bars. For systems
up to four sections, two support braces are needed, one attached to the motor
drive and one to the base section. For larger systems, a third support brace
should be mounted near the center of the mechanism, as shown in Figure 2-4.
