The CPS 4B240A200 is a heavy-duty bottom dump trailer engineered for high-volume hauling of aggregates, sand, and construction materials. With a 20 cubic yard single hopper capacity (expandable to 23 yards with bangboards), this 40-foot trailer delivers efficient discharge through a 54" x 108" opening and commercial-grade steel gates. Built with lightweight 10GA and 12GA steel, it balances strength and payload optimization. The tandem air ride suspension, electric tarp system, and dual-mode gate controls (cab and ground) make it ideal for demanding job sites and highway transport. California-legal and DOT-compliant, this trailer is ready for rigorous fleet use.
