An Inverted Power and Free Conveyor utilizes a single
enclosed track combining the power chain and the free trolleys.
The power & free system uses fixed chain dogs that engage the
pivotal free trolleys to move them through the system.
Disengaging the free trolley from the chain dog allows for free
trolley accumulation.

These systems are most commonly used when moving lighter
parts. Areas of use include production areas or delivery systems
that require accumulation such as general assembly, body shop,
painting and oven drying.
