The HKD 302-S with its hydraulically opening side panels is an all-rounder. With them, it can cope with unloading even poorly sliding cargo loads, like maize for silage or compost, for example. For lighter bulk cargo, the loading volume can be designed to be up to 29 m³ (in a combination with two trailers a huge 58 m³). These tippers also remain a fully-functional three-sided tipper.
