The present invention relates to a braking device (1) for controlled lowering of tree branches or trunk pieces during tree pruning and plant removal performed by rope arborists. This braking device consists of two functionally connected units: a braking unit (10) designed so as to control the rotary motion of a rope drum (12) having wrapped therearound a rope (30) whose one end is tied to the tree branch or trunk piece to be lowered; a control unit (20) which controls a brake capable of exerting a friction force on said rope drum so as to limit or stop its rotary motion. Unlike known lowering brakes, said braking device is characterized in that the rope wrapped around the rope drum is not subjected to overheating generated by the dynamic friction. Moreover, it can advantageously control in real time the fall of the branch.
