The Libec DL-3RB is a standard folding dolly for tripods, used to move a camera and tripod smoothly across a studio or event floor and to make dolly shots in any direction without tracks on smooth, hard surfaces. It is designed for Libec's RT20C, RT30B, RT40RB, RT50B and RT50C tripods, as well as Libec LX, RS and RSP 750 series systems, and it also fits selected Sachtler, Vinten and Manfrotto tripods using its adjustable rubber tripod attachments. It carries loads up to 45 kg and weighs only 3.9 kg. Each of the three 10 cm casters has its own foot-operated lock and release pedal for stability once positioned. A carrying handle is built into the centre section and the arms fold together for storage and transport; the dolly is designed to pass through a 90 cm doorway. It is a practical accessory for broadcast studios, live-streaming setups, lecture capture and event videography. Tripod and camera are not included.
