The KESLA 671H has long been a well‑known parallel-acting harvester crane used in thinning harvesters, like Sampo-Rosenlew HR46 among others. The crane is known for its excellent handling and durability. In addition to the non-telescopic 671H, which reaches 6.7 meters, the product line has for years included the telescopic 685H, offering a reach of 8.5 meters.
The 6H series has undergone numerous updates that further enhance durability. At the same time, new HF versions have been introduced, featuring a slewing device equipped with a horizontal mounting flange. In terms of boom structure, reach, and performance, the H and HF versions are identical.
Thanks to the horizontal mounting flange with the commonly used 8 × 175 mm bolt pattern – well known from forwarder cranes – and the configurable orientation of the slewing cylinders, the 6HF cranes are compatible with most lightweight harvesters currently on the market. The robust crane base, inherited from the 8‑tonne‑meter forwarder crane, ensures exceptional durability. The slewing device provides a 275‑degree slewing range and delivers 17 kNm of slewing torque, enabling productive and efficient thinning operations.
“The market for lightweight thinning machines is looking lively, and the new crane version has already attracted considerable interest among several forest machine manufacturers,” says Mika Tahvanainen, Product Management Director at Kesla Oyj. “Together with the KESLA 16RH and 18RH‑II harvester heads, the crane forms a perfect solution for lightweight thinning harvesters,” Tahvanainen continues.
