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. |
