The Guardian SP .300C Combo Chassis with Combo Dry and Combo Liquid systems offers higher operating productivity with ease of transition for operations where both liquid and dry applications are required. Switch systems in minutes using a crane or 10,000-lb. lift capacity telehandler and quick-attach coupler system. Spring-loaded front mounts loosen and swing away for fast changes, and spring-loaded rear mounts on the dry box loosen easily. The liquid skid, tank, product circuit and boom all come off in one assembly.
