The invention discloses an energy-saving tower crane using counterweight. The energy-saving tower crane comprises a tower body, a hoisting assembly and a counterweight assembly, a jacking beam is installed on the surface of the top of the tower body in a sliding mode, and the counterweight assembly is installed in the tower body in a penetrating mode. The counterweight assembly is installed in the tower body in a penetrating mode, a counterweight can be arranged in the tower body, a steel wire rope is reversely wound to a winding drum used by a hoisting mechanism for upward guiding, when a lifting hook is in a half load state, the weight of the lifting hook and the weight of the counterweight are basically equal, and at the moment, a motor only needs to overcome friction force to do work so as to drive the winding drum to conduct hoisting. At the moment, the most labor-saving and energy-saving effects are achieved, a tower crane counterweight weighing balance system is introduced, the system has the main function of relatively balancing the weight of the lifting hook, the weight difference between the lifting hook and the counterweight can be kept within the limit range in the working process of the tower crane, normal traction transmission of the hoisting mechanism is guaranteed, and the system is used for balancing the weight of the lifting hook and the weight of a hoisted object. After the counterweight is used, stable operation of the tower crane is ensured, and the power of the motor is smaller than that when the motor is not used.

    本发明公开了一种使用对重的节能塔机,包括塔身、起重组件和对重组件,所述塔身的顶部表面滑动安装有顶升梁,所述塔身的内部贯穿安装有对重组件。本发明通过在塔身的内部贯穿安装有对重组件,能够利用在塔身内布置对重,通过钢丝绳反向卷到起升机构所用的卷筒上引,在吊钩半载的时候,吊钩和对重的重量基本相等,此时电机只需克服摩擦力做功就可驱动卷筒进行吊运,此时最省力、节能,引入塔机对重也称重量平衡系统,该系统的主要功能是相对平衡吊钩重量,在塔机工作中能使吊钩与对重间的重量差保持在限额之内,保证起升机构的曳引传动正常,用来平衡吊钩和吊物重量的,使用对重后保证塔机运行平稳,电机的功率可比不用时减小。
