Abstract

The tree is held in position for its branches to be stripped off by a tube (10) fixed underneath the lopping-machine by means of bolts (11). The tube is slipped over the tree-trunk (28), and its dimensions vary with those of the tree. A jack (23) is fixed to the tube (10) to transmit vibrations to the trunk (28). The jack (23) with casing (24) and piston (25) can be a double-acting one with two pipes (26, 27) connecting the jack to a distributor and pump. The vibrator can be a circular or undirectional vibrator. Cogged wheels (3, 4) are driven by motors (5, 6). At the top, the vibrator has a vibration-deadener consisting of springs (8) positioned between the housing (7) and the lever-hook (9).
