| description | The invention relates to the field of tower type pumping unit brake devices, in particular to a tower type crane flexible brake device which comprises an operating lever frame, a brake operating lever, a fork head, a flexible brake cable, a U-shaped bolt, a pull rod cam, a brake shoe, a pressure sensor and a central control module. The operating lever frame is formed by integrally welding a toothed plate, a side plate, a bottom plate and a cross arm, the brake operating lever is formed by welding a brake handle, a knife switch, an extension spring, a clamping plate, a connecting strip and a spring handle and connecting the brake handle with bolts, and when the flexible brake device is adopted for braking, the brake operating lever is connected with a U-shaped bolt, the U-shaped bolt is connected with a flexible brake cable, and the flexible brake cable is connected with a fork head. The fork head is connected with a pull rod cam, and the pull rod cam brakes and holds tightly on a brake shoe to achieve the pur |
