>winding drum is the component to wind wire rope in the lifting mechanism. Rolling drum consists of drum shaft,Â
flange type annular gear,drum hub, bearings, bearing pedestal.When one end of drum is equipped with the switch of rotary type position limitation limiter, it must ensure to make drum shaft and rising limit switch rotate synchronously.
->Drum material generally adopts cast iron. For special use, drum can be weld with cast steel or steel plate.

 | Cast steel type crane drum  1. The material of this kind of crane drum is cast steel. 2. It is rarer than cast iron type and steel plate crane drum because of the lower  castability. 3. Centrifugal casting is used in the process of production. |
||
 |  Stell plate type crane drum  1. The material of this kind of crane drum is steel plate, Q235, Q345. 2. It is more common than cast steel type crane drum. 3. Welding is used in the production process of steel palte type crane drum . 4. It is easy and convenient to produce.  |

Melt-blown microfibers generally have diameters in the range of 2 to 4 mm, although they may be as small as 0.1mm and as large as 10 to 15mm. Differences between melt-blown nonwoven fabrics and other nonwoven fabrics, such as degree of softness, cover or opacity, and porosity can generally be traced to differences in filament size. The most commonly accepted and current definition for the melt-blown process is: a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor or take-up screen to form a fine fibrous and self-bonding web.The melt-blown process is similar to the spunbond process in that both convert resins to nonwoven fabrics in a single integrated process.
