Ponsse's sliding boom-style HN harvester cranes have become a concept in their own right in the CTL forest machine market. For almost two decades now they have been a trademark of Ponsse harvesters and one of the key factors in their efficiency.Thanks to its low structure and strong turning device based on a slewing drive, the P0NSSE HN has an extremely low centre of gravity, guaranteeing stability across the entire extent of its reach. Its tiltable vertical boom and quick extensions produce a swift linear movement from machine to tree, and the co-ordination of the optimally placed power arms makes handling even sizeable pieces easy.
All components of the Ponsse cranes are manufactured using the latest manufacturing technology and are subject to continual quality assurance monitoring. The booms are machined only after all the welding has been done, ensuring the extremely high measurement precision of the components. This adds to the components' service life and facilitates their installation. Critical welding seams are finished using TIG welding. On top of all this, every fourth component manufactured is sent for special laboratory testing in which the manufacturing quality of critical points is inspected with ultrasound, penetrant solution, and other non-destructive materials testing methods.
Unbeatable properties combined with high manufacturing quality and reliability have ensured the popularity of HN cranes throughout the world, year after year.
