The Sachtler Dolly 75 turns most 75mm-bowl tripods into a rolling support — Sachtler names a handful of 75mm exceptions, including flowtech, SOOM and the system Ace M MS / L TT 75/2 CF / XL TT 75/2 CF lines — giving smooth, stable dolly action across a floor. Independent wheel locks let each wheel be held in place, so the tripod can be parked steady or freed to roll as the shot needs. It folds to a collapsed length of only 25" for transport, and the carry handle is moulded into the dolly's reinforced centre bracket — putting the lifting point where the structure is strongest.
