The front loading arbor
(FLA) is an arbor configured to receive its counterweight
bricks from the front rather than from the side.
The benefits include:
it results in a safer loading ergonomic,
it accommodates shelves, which allows for easier loading,
it results in shorter arbors for a given weight requirement,
the arbors can be single, double and triple wide, thus reducing travel height requirements even further.
The FLA was granted North American pending patent and licensed to Thern Stage
Equipment in 2009.
