22JLF15 Hoisting Mechanism for 6t Tower Crane  

Tower Crane Parts : 22JLF15 Hoisting Mechanism Tower crane mechanism is one of the most important tower crane parts. Tower crane has three common mechanisms that is hoisting mechanism, trolleying mechanism, and slewing mechanism. Hoisting mechanism 22JLF15 is popular used for 6 ton tower crane.  JLF series hoisting mechanisms adopt the structural style of variable frequency motor+S-NGW reducer+winding drum.S-NGW reducer is empolyed for the first time in China with the precision of all gears(through grinding processing) up to 6 level and features of less noise, compact structure, light weight and convenient maintenance. Winding drum of major diameter and lebus grooves is adopted with good rope-arranging performance to increase wirerope's service life. Due to stepless speed regulation and steady operation, it reduces the impact on the components and mechanisms of the tower crane and achieves the slow position with toward zero speed which is covenient to precise ho…
