The invention relates to track systems 14, 14′ that may be used to convert steerable, all-wheel drive construction equipment to steerable, multi-track construction vehicles 10. A preferred embodiment of the track system 14, 14′ includes a frame 60, 182 having a reinforcing enclosure 150, 230, a plurality of track engaging rollers 82-86, 202-206, a sprocket 102, 214, and an endless track 76, 198 operatively connected to the frame 60, 182. Tension on the endless track 76, 198 is maintained with two tensioning members 170, 244 operatively connected to the forwardmost roller 82, 202. The track system 14, 14′ preferably includes a limiting apparatus 300 that is configured to restrict the rotational movement “r” of the frame 60, 182 relative to a vehicle axle 16 to which it is attached. The limiting apparatus 300 has a first component 40, which is associated with the vehicle axle 16, is configured and arranged to interact with a second component 262, which is associated with the frame of the track system 14, 14′. Preferably, the limiting apparatus 300 is adjustable such that the range of rotational movement “r” can be varied.

1. A track system comprising: a frame having a first end and a second end, the frame having inboard and outboard frame assemblies that extend between the first and second ends of the frame;a drive sprocket mounted between the inboard and outboard frame assemblies such that the inboard frame assembly is inboard of the drive sprocket and the outboard frame assembly is outboard of the drive sprocket, the drive sprocket being rotatable relative to the frame about an axis of rotation;a first end roller mounted at the first end of the frame;a second end roller mounted at the second end of the frame;a track routed in a generally triangular path about the drive sprocket and the first and second end rollers, the track being driven by the drive sprocket about the generally triangular path when the drive sprocket is rotated about the axis of rotation; andinboard and outboard cylinders for moving the first end roller relative to the frame to tighten the track, the inboard and outboard cylinders being in fluid communication with one another, the inboard cylinder being inboard of the drive sprocket and the outboard cylinder being outboard of the drive sprocket;wherein the generally triangular path of the track has an apex, and wherein the drive sprocket engages the track adjacent the apex to drive the track about the generally triangular path; andwherein the track defines a bottom side of the generally triangular path that extends between the first and second end rollers, wherein the track system includes first, second, third and fourth intermediate rollers for supporting the track along the bottom side of the generally triangular path, wherein the first, second, third and fourth intermediate rollers are positioned between the inboard and outboard frame assemblies, wherein the first, second, third and fourth intermediate rollers are respectively mounted on first, second, third and fourth cantilevered shafts, wherein the first and third cantilevered shafts are supported by the inboard frame assembly and the first and third intermediate rollers are respectively mounted on the first and third cantilevered shafts adjacent the inboard frame assembly, wherein the second and fourth cantilevered shafts are supported by the outboard frame assembly and the second and fourth intermediate rollers are respectively mounted on the second and fourth cantilevered shafts adjacent the outboard frame assembly, and wherein the drive sprocket passes between the first and second intermediate rollers and between the third and fourth intermediate rollers as the drive sprocket is rotated about the axis of rotation. 2. The track system of claim 1, wherein the first and second cantilevered shafts are co-axially aligned and the third and fourth cantilevered shafts are co-axially aligned. 3. The track system of claim 2, wherein the first and second end rollers are positioned between the inboard and outboard frame assemblies and are mounted on end roller shafts each supported by the inboard and outboard frame assemblies. 4. The track system of claim 3, wherein the first and second end rollers each include first and second flanges, and wherein the drive sprocket passes between the first and second flanges of the first and second end rollers as the drive sprocket is rotated about the axis of rotation. 5. The track system of claim 4, wherein the inboard and outboard frame assemblies are interconnected at a first interconnection location positioned above the first end roller, wherein the inboard and outboard frame assemblies are interconnected at a second interconnection location positioned above the second end roller, wherein the inboard and outboard frame assemblies are interconnected at a third interconnection location positioned between the first end roller and the first and second intermediate rollers, and wherein the inboard and outboard frame assemblies are interconnected at a fourth interconnection location positioned between the second end roller and the third and fourth intermediate rollers. 6. The track system of claim 5, wherein the first and second interconnection locations include struts that extend between the inboard and outboard frame assemblies. 7. The track system of claim 6, wherein a conduit for fluidly connecting the first and second cylinders passes through the strut of the first interconnection location.
