The invention discloses a chain block with a load limiting function and a using method thereof, and belongs to the technical field of chain blocks, the chain block comprises a chain block main body, a hand pulling transmission assembly is installed on the chain block main body, and the hand pulling transmission assembly is connected with a brake transmission assembly used for brake protection. The brake transmission assembly is connected with the chain block body, and a double-chain-wheel lifting device is installed on the brake transmission assembly. The chain block body is connected with a lifting assembly used for lifting the chain block body to the installation position, and the lifting assembly is used in cooperation with the hand pulling transmission assembly. By means of the mode, installation of the chain block can be achieved without an external lifting assembly, and during large-load stretching, compared with a single chain wheel lifting chain block, the chain block has better stability, meanwhile, abrasion to components is reduced, and the service life is prolonged.

    本发明公开了一种具有限载功能的手拉葫芦及其使用方法,属于手拉葫芦技术领域,包括手拉葫芦主体,所述手拉葫芦主体上安装有手拉传动组件,所述手拉传动组件连接有用于制动保护的制动传动组件,所述制动传动组件和手拉葫芦主体连接,所述制动传动组件上安装有双链轮起重装置;所述手拉葫芦主体连接有用于抬升手拉葫芦主体到安装位置的抬升组件,所述抬升组件配合手拉传动组件使用。通过上述方式,本发明实现了无需外置抬升组件,就可实现手拉葫芦的安装,在大负荷拉伸时,相比单链轮起重本手拉葫芦具备更好的稳定性同时对部件的磨损减小提高了使用寿命。
