3.3 Drive Section

Two different drive designs are available for RZPAC conveyors. The screw (fixed) takeup drive is the
least expensive option and is available for conveyor lengths up to 100 ft and total product loads up to
1050 lbs with a laced belt or 3200 lbs with a hot-spliced belt. Because the screw takeup drive is manually
tensioned, it requires periodic tension adjustment as the belt elongates. See Table 6: Recommended
Preventative Maintenance Schedule in section 6.2 for the required belt retensioning frequency.

Figure 2: Screw Takeup Drive Overview

The pneumatic takeup drive offers a low-maintenance automatic tension adjustment and a longer belt
takeup distance for conveyor lengths up to 200 ft, or heavily-loaded conveyors. Since the pneumatic
takeup automatically adjusts belt tension based on the conveyor load, it can handle heavier total product
loads, up to 1900 lbs with a laced belt or 4100 lbs with a hot-spliced belt.
