The RailDolly Carriage in the Traveler Kit has a larger footprint than some of our other options so it provides a more stability when using a full-size broadcast camera or similar. This portable camera dolly is also a good option for critical audio recording because operation is silent with it’s semi-soft wheels. This configuration uses one RigPlate, two RigAxles and two different types of skate wheels. Another capability with the RailDolly Portable Camera Dolly is the ability to use it on square or rectangular rails. Square or rectangular rails can be much more rigid than tube/pipe so if you’re going to be putting a BIG camera rig in motion this is an ideal option. This configuration also included the parts to configure our RigSkate so you get 2 great options for movement.
