Abstract: A twin lifting machinery for two 40 feet container shore crane is disclosed, comprising motors, high speed shaft brakes, two reductors, a plurality of multiple-project rope reels, and a plurality of reel brakes; wherein at least two motors and two reductors are provided; the input shafts of said two reductors connect to one of the output shafts of the motors respectively, and the output shafts of each reductor connect to the reels, the reel brakes are provided on each reel respectively. The synchronous operation or individual operation of two sets of lifting machineries under electrical control can be carried out, achieving the lifting and lowering operation of two hanger tools of sea side and land side The twin lifting machinery thus can carry out both the synchronous operation of two hanger tools and the individual operation of a single hanger tool, increasing the loading and unloading efficiency of the container crane by more than 60%.

Abstract: The present utility proclaims an automatic corneal epithelium separation device characterized in the following including: a dual-motor assembly comprising two motors, with a connecting key fixed below; a separator, with an inner-round via-hole connecting up and down, a separating piece on its one side and a check arm extending out on its upper surface; a suction ring assembly comprising a suction ring, with a suction ring stud on the upper plane, on the ring face of which a flat key slot is positioned, and a connecting tube is connected with the suction ring integrally through a stop ring fixed at its one end. The present invention can separate corneal epithelium from Bowman's membrane rapidly and easily without the use of alcohol and other chemicals. It prevents the epithelium from being loosened. It separates the epithelium continuously and protects the stroma bed and the epithelial flap after separation. It is a kind of epithelial microkeratome without using alcohol, that is automatic rotating EPI-LASIK.
