Manual Chain Hoist Structure

图片
  CB type hand chain hoist When Manual chain hoists lifting weights upward, hands and pulled clockwise chains, bracelets wheel rotates counterclockwise when pulling hands to pull the chain down the stopper with separate brakes, ratchet pawl still under the effect of the five tooth long axis lifting sprocket drive runs in the opposite direction, so that the weight steady decline. Chain hoists generally use one-way ratchet friction disc brake, brake in the load on their own, with the ratchet pawl engages under the action of the spring, the brake safety. It is safe, reliable, easy maintenance, high mechanical efficiency, bracelets pull small, light weight and portability, smaller size and beautiful appearance, durable and suitable for factories, mines, construction sites, wharves, docks and warehouses for installation of equipment, lifting goods, especially for open and no power supply, but also shows its superiority. Selection of main parts chain hoists steel materials, the use...

Bridge Crane and Overhead Crane Systems

  Bridge Crane = Overhead Crane = Overhead Bridge Crane This issue may be too elementary for many of you, please kindly note that Bridge Crane, Overhead Crane System and Overhead Bridge Crane are different titles for the exact same thing. This results in the customer meaning one thing while the design engineer is thinking of something entirely different.   The main travelling structure which spans the width of the bay is the Overhead Bridge Crane. The bridge consists of two end trucks and a bridge beam (bridging between the two end trucks).   End carriages/trucks: Located on either end of the bridge beam are the end trucks. They provide a connection point between the bridge beam and the house the wheels on which the entire crane travels. These wheels ride on the runway beam allowing access to the entire length of the building. Bridge Girders/Crane beams: The horizontal beam of the crane bridge supports the hoist. There can be either one or two bridge beams, but we’l...

overhead crane classification, gantry crane classification

  Crane   classification s of various types of cranes for you to pick up right   overhead crane   and gantry crane for your application. Overhead   crane duty classification   and gantry crane classification are presented for you. Please check now. Crane classification Crane classification is determined by two kinds of ability; first is the frequency of the use of a crane, called the crane use level; second is the crane load bearing, referred to as the crane load condition. 1.Crane use level Crane has certain work cycles during the useful life time.  crane operation  work cycle is the whole operation process starts from the preparing of lifting items, until the next lifting. Total work cycles show crane utilization degree, it is one of the basic parameters of crane level classification. Crane total work cycle is the sum of crane working cycles during the service life. When determine the appropriate crane service life, it need to consider the econo...
