The invention provides a tower crane and a hanger assembly of the tower crane. The hanger assembly comprises a hoisting steel wire rope; the first end of the hoisting steel wire rope is sequentially wound around a second pulley of a master trolley, a first pulley of a master hanger unit, a fourth pulley of the master trolley, a first pulley of the master trolley, a second pulley of the master hanger unit, a third pulley of the master hanger unit, a third pulley of the master trolley, a first pulley of a secondary trolley, a first pulley of a secondary hanger unit, a third pulley of the secondary trolley, a second pulley of the secondary trolley, a second pulley of the secondary hanger unit, a third pulley of the secondary hanger unit and a fourth pulley of the secondary trolley and then is connected with a hoisting mechanism of the tower crane; and a second end of the hoisting steel wire rope is fixedly arranged. According to the tower crane and the hanger assembly of the tower crane disclosed by the invention, an eight-magnification hanger assembly is formed in a manner that the master trolley and the secondary trolley are respectively combined with the master hanger unit and the secondary hanger unit to respectively form a four-magnification unit; and while the magnification is increased, the width of the hanger assembly is reduced, and the minimum working range of the hanger assembly is reduced.
Description
technical field [0001] The invention relates to the field of cranes, in particular to a tower crane and a hook assembly thereof. Background technique [0002] The hook assemblies in the prior art are usually double-rate, quadruple-rate or six-rate, and usually two or three double-rate units are combined to form a four-rate or six-rate hook assembly. [0003] figure 1 A schematic structural view of a six-magnification hook assembly in the prior art is shown. Such as figure 1 As shown, the six-magnification hook assembly in the prior art includes a first trolley 1', a second trolley 2', a third trolley 3', a first movable pulley 4', a second movable pulley 5' and a third movable pulley 6', Among them, the first trolley 1' and the first movable pulley 4', the second trolley 2' and the second movable pulley 5', the third trolley 3' and the third movable pulley 6' form a double-rate unit respectively, and in the above three double-rate A hook body 7' is arranged below the uni...
