FIELD: equipment for tree felling by uprooting with the use of hydraulic means. ^ SUBSTANCE: apparatus has power unit attached to tree trunk holding frame, to carrier frame, and to lifting cylinder. Tree trunk holding frame is attached to trunk holding mechanism capable of gripping tree by means of levers. Tree trunk holding frame is coupled to pushing cylinder. Carrier frame is attached to supporting roll for rotation. In case of joined arrangement of carrier frame, two parts of carrier frame are moved by means of adjustment unit. Upper part of pushing cylinder is coupled to any part of carrier frame. Other end of lifting cylinder is connected to carrier frame or, in case of rigid connection arrangement of carrier frame, one end of adjustment unit is connected to said frame while other end is coupled to pushing cylinder. Lifting cylinder can be connected to tree trunk holding frame directly or through pivotally joined power transmission. Apparatus is adapted for felling trees of various sizes. ^ EFFECT: simplified construction, enhanced reliability in operation, increased operative safety, and wider operational capabilities. ^ 15 cl, 2 dwg, 2 ex |
