A track system for a camera dolly comprises two tubular rails 6 supported by a support system comprising a plurality of support elements 9a provided with bases 65. The support elements 9a are height adjustable to vary the height of the rails 6 above the bases 65. Intermediate support elements 45 which are not in contact with the ground can be provided when the normal support elements 9a are spaced widely apart. These intermediate supports 45 are supported by cables or rigid members extending from adjacent support elements 9a. The rails 6, which are preferably packed with an acoustic damping material, are formed in sections which are coupled together by an expanding sleeve joiner. A camera dolly is also disclosed. <IMAGE> |
