The Cross Country 393SDXL and 292SDX form a Super-B side dump train that moves 33.2 cubic yards water level in a single 63-foot combination. Both units are built on 100,000 psi hi-tensile premium steel frames with Hardox 450 wear-plate floors, and both dump under the same controlled SDX action. Manual and load-sensing lift axles are available to manage weight distribution across the combination.
