3.1 Overview
The Roller Live AC (RLVAC) conveyor is designed for longer runs of transport conveyor in applications

adjustable spring tension.

3.2 Belt
The main conveying belt is 99mm wide and is available with two different joining options.
The laced belt is quick to install and quick to repair, and does not require special tools or expertise with
the lacing factory installed. It is well suited for any conveyors within its load capacity (light to medium
product loads, or heavy loads on shorter conveyors).
The hot-spliced belt requires special tools and skills to create splices, and cannot be installed or replaced
as rapidly due to the minimum time for the splices to heat and cool. However, it is a more durable option
that is necessary for very heavy loads (working strength of the hot splice is about 2.7 times the working
strength of the lacing) and is maintenance-free for the life of the belt. The hot-spliced belt is also quieter
because there is no metal lacing contacting the conveying rollers.
3.3 Drive Section
Two different drive designs are available for RLVAC 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
