The invention relates to building construction machinery and provides a tower crane hoisting mechanism brake automatic balance compensation device. The crane hoisting mechanism brake balance compensation device comprises an arc-shaped rack, sector ring teeth, a sector ring tooth clamping plate, a sector ring tooth outer clamping plate and a tension spring. The arc-shaped rack is provided with sawteeth I. The sector ring teeth are provided with sawteeth II meshed with the sawteeth I on the arc-shaped rack. The sector ring teeth are clamped between the sector ring tooth clamping plate and the sector ring tooth outer clamping plate. A crane hoisting mechanism brake composed of the balance compensation device comprises a brake releaser, a hydraulic oil cylinder, two groups of brake arms, brake arm torque springs, two groups of brake blocks and adjusting screws. The two groups of brake blocks are hinged to the two groups of brake arms through articulated shafts II respectively. The crane hoisting mechanism brake further comprises the balance compensation device. The crane hoisting mechanism brake balance compensation device greatly improves the operating reliability and durability of a hoisting mechanism brake system, reduces the maintaining frequency of the brake system and is simple in structure, economical and practical.
