Engnieering chain and Conveyor Roller chain
Dongchuan SP (Super Premium) is stronger than the standard ANSI roller chain.  This is achieved by manufacturing the chain from a higher grade steel with more heat treatment.  SP chain has a higher tensile strength of about 28% more over the standard ANSI roller chain. The SP chain is generally used in high shock load situations that offers greater fatigue resistance.

Offset links (Half links) are not available for the SP (Super Premium) roller chain. We do not recommend installing offset links on the Super Premium roller chain.
 

• Meets and exceeds ANSI B29.1 specifications
• Roller chain components are shot peened for greater fatigue resistance
• Heat treated components for increased durability, longevity and wear resistance
• Chain is pre-loaded (Pre-stretched) to eliminate initial stretching.
• Chain components are lubricated before assembly, then dipped in a hot oil bath after assembly

The engineering chain and conveyor chains listed on this page are produced by Dongwu, a morden conveyor chain manufacturer based in China, these products are especially designed for automated logistics equipment , material handling equipment, engineering vehicles, and more.  We produce chains according to your customized requirements.
 

Galle chains are applied in many hoisting constructions, such as locks, slipways, upward pressure damming constructions, cranes etc.

In addition to the standard DIN 8150, DCC's engineering department has optimized many of those chains, and has found solutions to make them low-maintenance chains.

Because of the safety requirements, many of the applications of Galle chains are subject to strict certification and testing procedures. 
DCC is familiair with those procedures.
If you are interested, or if you have any questions, please contact our sales department.
