Ballast; Counterweight - Beta Max Beta Lite Manual Del Usuario

Ballast

A counterbalance (or ballast) system uses two rigid metal containers, each with a
capacity of 9.5 cubic feet (269 liters), bolted to the inboard (rear) Trestle Monorail
leg. The weight of the material in the containers counterbalances the combined
weight of the workload and the hoist at the outboard end of the Trestle Monorail.
Ballast material must conform to certain requirements. Suggested materials to use
for ballast are: bricks, solid concrete blocks, stone, or other high-density nonflow
material. Liquids can not be used and loose sand, in some installations, may not be
a suitable choice. Each container should be filled to the maximum capacity for
maximum stability.

mounting hardware securely attach the upright to the inboard Trestle
Monorail legs. Standard 50-pound (22.7-kilogram) counterweights slide
down over the upright and counterbalance the system.
