Abstract
A lifter used for building construction comprises a hoister, a wire rope, an assembly pulley, as well as a cradle which is equipped with a rope breaking resistant device and a stop layer mechanism. When the cradle stops at the layer, the mobile gate is opened, a touch platform on the gate propels a cam through a touch rod on the stop layer mechanism, thereby forcing a brake block at beveling position uplift the horizontal level and dive into a guide rail cross beam, and making the cradle be on self-locking status, the stop layer is safe and reliable. When the wire rope suddenly breaks in the operation of the cradle, a lever on the rope breaking resistant device immediately raises the brake block at beveling position to the horizontal level and clamps on the guide rail cross beam under the action of a tension spring, thereby preventing the cradle from falling. The lifer has simple structure, and the rope breaking resistant device and the stop layer mechanism are convenient for cleaning and maintenance. The cradle sliding guide rails are set as two-side two-rail with steadier running. In addition, the moving gate from top to bottom also saves the space in front of the cradle, which is convenient for unloading and loading.
