crane drum materials
What Material Is The Crane Drum Made of?
Drum is one of the important components of the lifting mechanism on the crane, storage of wire rope, rolling control hook lift, play a big role. Crane drum is also by winding wire rope, and directly bear the role of the load, so its quality must meet the requirements. Quality often has a lot to do with the material, so what is the crane drum material?
Crane drums are mainly made of iron and steel in the following forms:
Cast Iron Drums
Cast iron drum is generally used for lifting the smaller equipment, the use of grey cast iron not less than HT200, slightly higher requirements can be used for high-strength cast iron or ductile iron QT40 and so on. Grey cast iron drum process is relatively simple, low melting point of the material, easy to produce. Hardness is not high, small wear and tear on the wire rope, but low strength, can not withstand large impact, otherwise easy to deform even cracks. Mostly used in light grade, intermediate work level. Ductile iron reel than grey cast iron reel strength, toughness and impact resistance to some higher. Cast iron drum using sand cast iron casting process, cast iron due to itself in the casting of good mobility, casting defects is relatively small, but need to go through aging treatment.
Cast Steel Drums
Cast steel drums often use a variety of carbon steel or alloy steel, such as lower production costs, higher strength, toughness and plasticity, impact resistance. The surface is hard, easy to wear on the wire rope. Cast steel drums are mostly used in heavy and extra heavy duty conditions. The steel of cast steel is not as fluid as cast iron and is prone to defects such as porosity and needs to be annealed.
Steel Plate Welding Drums
Steel plate welded drum is often used Q235B or Q345B carbon alloy steel plate, good overall performance, good low temperature performance, good cold stamping performance, good welding performance and cutting performance. Steel plate welding drum production, the cut steel plate, through the cold roll of the coiler, in the welded into, and then annealed and subsequent cutting processing. Steel plate welded drum has good comprehensive performance, high strength, high hardness, good wear resistance, strong impact resistance, and is very suitable for the production of large diameter drum. It is suitable for all kinds of medium-sized or heavy cranes, and can meet the needs of the more complex working environment.
With the modernisation and construction process faster and faster, the requirements of lifting machinery is also higher and higher, lifting machinery to large-scale, automation, specialisation trend. Therefore, it can be known at the same time, the crane reel will also be large, large rope capacity, high performance development. This requires the crane drum has a larger size to accommodate longer wire rope; with a higher hardness, strength, abrasion resistance, impact resistance, corrosion resistance, etc., to adapt to the work of higher intensity, more complex environment.
GloryRail provides crane rails and related accessories supply and service for a variety of industrial projects. Through close cooperation with major rail production factories, GloryRail has established a spot warehouse for rail materials, and at the same time built two production lines for square steel flat steel rails, realizing the supply of all types of lifting rails. After years of rapid development, the accessories processing factory has iteratively upgraded production equipment and production lines and is equipped with the latest forging equipment to ensure product quality and performance. The steel structure workshop can produce conventional crane blocks, buffers, embedded parts, etc., and can also provide drawing processing services.
