Updated From Kesla Oyj: 6H Series Small Harvester Cranes

Kesla Oyj is expanding its small harvester crane product line by introducing new, more versatile versions. The updated 6H series meets the growing demand for lightweight thinning machines and offers an even more durable crane solution with improved operating characteristics.

The Kesla 671H has long been a well‑known parallel-acting harvester crane used in thinning harvesters, and the crane is known for its excellent handling and durability. In addition to the non-telescopic 671H, which reaches 6.7 m (22 ft.), the product line has for years included the telescopic 685H, offering a reach of 8.5 m (28 ft.).

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° slewing range and delivers 17 kNm of slewing torque, enabling productive and efficient thinning operations.
