Abstract: An improved track system for movable apparatus for handling materials such as conveyor apparatus for distributing concrete mix and the like, comprises a plurality of track sections pivotally linked together, with each section comprising a tubular upper member mounted by means of struts on two parallel tubular lower members. The lower members are curved inwardly at one end and are beveled inwardly at the other end, so that two joined sections will mate and will form a substantially continuous outer surface even when the two sections are arranged obliquely. A carriage for the track comprises at least one inverted V-shaped member riding along the track on a load caster mounted at the apex of the member. Guide casters mounted at the ends of the legs of the member ride along the lower tubular members and provide lateral stability for the apparatus mounted on the carriage.

Abstract: A support for a camera dolly comprising spaced-apart first and second rails comprised of longitudinal rail members. The first rail has a first seam between its rail members, and the second rail has a second seam between its rail members. The first seam in the first rail is directly opposed from a corresponding second seam in the second rail. The first and second seams have first and second leading edges formed at crowns on the first and second rails, and the leading edge of the first seam is offset longitudinally with respect to the leading edge of the corresponding second seam.

Abstract: A rail for forming a track for a dolly, the rail including a roughly flat base (14), a crown (16) located operatively above the base for engagement by a wheel of a dolly, and two connecting webs (18, 20) fast with and connecting the base and the crown together, the webs converging towards each other away from the base, so that the rail has a generally' triangular profile when seen in end view.
Abstract translation: 一种轨道,用于形成用于小车的轨道,该轨道包括大致平坦的基部(14),位于操作地位于基座上方的用于由台车的车轮接合的冠部(16),以及两个连接腹板(18,20) 将基部和冠部连接并连接在一起,所述腹板彼此朝向彼此收敛,远离基部,使得当在端视图中看到时,轨道具有大致“三角形”轮廓。
