Abstract

A frontloading arbor apparatus for use in counterweight rigging operations configured to enable individual counterweight load adjustment within at least one of a plurality of discrete compartments while the remaining compartments are secured by one or more gate mechanisms, thereby limiting a potential inadvertent separation of the entire counterweight load during use. The frontloading arbor apparatus including a rigid support frame having a plurality of laterally oriented shelf members extending between a pair of sidewalls, a corresponding plurality of gate mechanisms for each of the plurality of discrete compartments, the plurality of gate mechanisms pivotably coupled to one of the sidewalls and configured to pivot between an open position and a closed position, and a corresponding plurality of latches for each of the plurality of gates, each of the plurality of latches configured to independently secure each of the corresponding plurality of gates in the closed position.
