JOBO ST50 is a stroke feeder developed for economical production in first thinnings and energy wood harvesting.
The harvester falls, twigs and cuts. Reliability and good delimbing result are basic but simplicity and low weight are major targets. The use of high tensile strength materials gives the possibility to gain low weight so that the harvester head can be attached to small tractors or excavators.
On the control unit, you select type of tree (SET 1 to SET 6) and length (six different lengths/tree stroke).
Selected length and measured length are indicated as well as production and total driving time. It has four driving programs (selected with F1-F4), for Combi driving with stroke and roller, only roller, MultiStem and MultiGrip for heavier wood.
The model has inductive sensors with an accuracy of 2,5 cm and reads feed in the front.
All functions of the unit can be controlled by two boxes located close to the crane control unit.
Where the terrain allows, the harvester can advantageously be mounted on excavators (5-9 ton).
For assembly, the bucket is usually replaced with a boom extension that can be fixed or hydraulically projected.
Excavators usually have enough oil flow and additional hydraulics that can be used.
With this small harvester, the production can be raised to a professional level. Despite the lower speed, the smooth combination reaches 4-6 m3 of production in typical thinnings.
