The updated 6H series is said to meet the growing demand for lightweight thinning machines and "offers an even more durable crane solution with improved operating characteristics". Well‑known parallel-acting harvester cranes and used in thinning harvesters, like the Sampo-Rosenlew HR46, the 6H range includes the 671H (reach of 6.7 metres) and the 8.5-metre long 685H. As well as the upgraded 6H range, Kesla is launching new HF versions, featuring a slewing device equipped with a horizontal mounting flange. The slewing device provides a 275‑degree slewing range and delivers 17 kNm of slewing torque, "enabling productive and efficient thinning operations". “Together with the Kesla 16RH and 18RH‑II harvester heads, the crane forms a perfect solution for lightweight thinning harvesters."
