Mac-Trac

For use only with the Scorpio Plus and Scorpio Plus XXL models, Mac-Trac
is designed for masons and chimney builders. Mac-Trac mounts to existing
4-, 5-, or 6-foot (1.2-, 1.5-, 1.8-meter) standard 1-5/8 inch- (0.3175-
centimeter-) tubular scaffold frames. The system is set for a 7-foot (2.1-
meter) cross brace and the Trac cantilevers 2 feet (0.61 meter) out over the
cross brace side of the scaffold tower. By removing the scaffold cross brace
at the work level and ensuring the cross brace is properly installed on the
frame above (use alternate horizontal brace at the level where cross brace has
been removed), the workload can be pulled in by hand and set down on a
work platform. For lifting larger loads, the system can be adjusted to raise
material up through the center of the scaffold to the work platform.
The Mac-Trac system consists of two supports and the Trac monorail. Two
identical horizontal supports span the 7-foot (2.1-meter) scaffold frame and set
down on the scaffold coupling pins. Gravity lock pins fasten the horizontal
supports to the coupling pins, and J-hook clamps secure the supports around the
top horizontal ledger of the scaffold.
The Trac monorail is a formed channel specifically made to accept the roller
wheels of the Scorpio hoist models. The Trac is slotted at the open end to make it
easy to slide the hoist into the Trac. Safety pins and keepers prevent the hoist from
rolling out of the Trac. The hoist and Trac can be positioned in the center, left, or
right of the 7-foot (2.1-meter) scaffold span by choosing the appropriate mounting
holes on the horizontal supports.
