Types of hoists

 As the name would suggest, hoists are devices used to lift or lower a load by using a rope or chain wrapped around a drum or lift-wheel. They can be powered by electricity, air pressure or by manual means. The component to which the load is actually attached to is called the lifting hook.

A basic hoist can be defined by two characteristics; the lifting medium it uses and its source of power. Regular hoists can use either wire rope that can be wrapped around a drum or something cylindrical, or a load-chain that is raised by a pulley and a profile to engage the chain in order to lift loads. The power supplied for hoists to lift weights can come from hydraulics, electrical or air driven motors. Despite the fact that hoists have been around since the 1800s, electrical hoists only came about in the early 1900s.

Hoists come as integral-package units or can be customizable. Integral-package units are cost-effective and can only be used for moderate applications. Customizable units allow for more access on the application of the hoist as a user can decide on which of the different parts he wants to use. However, these hoists are more expensive as compared to integral-hoists though they can be easily repaired and are more durable. The type of hoist a person selects depends on the application of the hoist.

Manual Chain Hoist Structure

  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

图片
  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...
