Tilting saw conveyor PTO
Cutting firewood at its best
The HMG rocking circular saw with a 4m or 5m telescopic conveyor belt from the WSK 7F series is available with a PTO connection or combined with an electric motor and is driven by a V-belt system. The drive is geared in such a way that energy-saving firewood cutting is achieved at low PTO speeds. The V-belts protect the drive systems and increase work safety. Thanks to the welded square steel tube frame, it achieves the highest stability. The large rocker enables quick loading of wood from the side and eliminates the need to open the lid, which ensures more effectiveness when cutting. This system is protected by a European patent (EP 3848170). In addition, the rocker is ergonomically and smoothly designed and is easy to operate thanks to integrated tension springs. The height of the rocker handle is adjustable for comfortable operation. In the WSK 7F-Z, WSK 7F-Z8 and WSK 7F-Z10 models, the conveyor belt is driven by its own oil supply and in the WSK 7F-T model by the tractor hydraulics. Using maintenance-friendly hand winches, the conveyor belt is extended from its compact transport position into the working position and adjusted to the desired ejection height. The conveyor belt consists of special studded textile segments that ensure faster removal of the conveyed goods. The conveyor belt speed can be adjusted from 0-91 cm/sec using an adjustable valve. Another special advantage lies in the design of the wood feed shaft, because the remaining piece of wood that no longer needs to be cut and remains in the rocker does not have to be thrown into the feed device by hand, but can simply be pushed through with the next log to be cut . A later retrofitting of components is possible at any time (e.g. electric motor for PTO drive).

In its 5/2020 issue, the magazine “Heimwerker Praxis” rated an HMG WE 7-8 tilting circular saw as “upper class” and with a grade of 1.4. An excerpt from the assessment: “… a great machine with a very high safety factor that makes making firewood a fun factor. Every euro is well spent here …” |
HMG machines are designed and manufactured according to principles valid machine guidelines. each machine a functional check is subjected to prior to delivery.
Boaters are to be audited, so HMG circular saws by the laboratory are checked. A valid type certificate is in any manual of the machine! |
