PROBLEM TO BE SOLVED: To provide a delimbing elivator flexibly responding the shape of a tree having large difference between the diameter of the lower part of a trunk and that of the upper part thereof and extremely varying in difference in diameters of the trunk at the intermediate part, making work more efficient due to perpendicular elivation, and delimbing desired branches into desired shapes. SOLUTION: This delimbing elivator is provided with the following: a travelling section 3 comprising an elevation driving motor and a plurality of drive wheels and training wheels; a tightening mechanism 5 comprising a pantograph jack for regulating pressure via a pressure control motor; a pressure controller 7 comprising a pressure sensor and a controlling circuit; a delimbing device 9 comprising a chain saw, a swing mechanism, a tilt mechanism, a rotary mechanism and a removable mechanism.
