The HKA combination trailer system is the considered choice: With just a few manipulations, the trailer can be modified from roll-off containers to a skip loader transporter. The lowerable, overridable and wear-resistant tongue system makes it easier to interchange the front loadable skip loader container. The ASK containers are tensioned with a Y-chain lashing on the trailer. A pluggable side-mounted centring fulfils the statutory requirements for load security. The HKA can also be equipped with the “safety-fix” quickaction clamping system. This trailer type is available in twin and triple-axle variants.
