Industry Application

Rigging and Cargo Control for Mining and Energy

Hoisting in shafts, winch systems and conveyor belt tensioning in mining and energy projects require chains, shackles, pulley blocks and turnbuckles that are built to withstand repeated stress, corrosive environments and heavy-duty lifting. Kailipu supplies the full rigging bill of materials for mining and energy applications from Qingdao on one purchase order, with components matched to the same strength level and tested to standard.

Industry Pain Points

What Goes Wrong in Mining and Energy

  • Chain links and shackles from different suppliers with mismatched strength levels, leading to an assembly limited by the weakest component
  • Shackles with a working load limit stamped but no traceability marking or material test certificate for audit purposes
  • Chain connectors that do not match the rail profile or mounting method of the mine cart or conveyor frame
  • Lifting chains with inconsistent surface finish or weld quality across batches, affecting corrosion resistance and service life
  • Pulley blocks and turnbuckles arriving without proof load testing records or dimensional tolerance checks
  • Multiple suppliers for different rigging components, causing delays and incomplete shipments for critical project phases
What Buyers Need

What Mining and Energy Buyers Actually Specify

  • Chain assemblies and rigging hardware with the same strength level and working load limit stamped on each component
  • Components tested to EN818-2, AS2321, ASTM973 or NACM2010 with proof load testing and breaking strength validation
  • Chain connectors and links designed to fit mine cart rail profiles and mounting brackets with confirmed dimensions
  • Surface finishes such as electrophoretic black, zinc plating or HDG to suit the corrosive conditions in underground or surface mines
  • One consolidated shipment with all rigging components for shaft hoisting or conveyor tensioning arriving together
  • Material Test Certificates to EN 10204 3.1 and traceability marking on each rated component for compliance audits

What chain grades are used in mining and energy applications?
Grade 80 and Grade 100 alloy chains are standard for lifting and hoisting. Grade 80 conforms to EN818-2, AS2321 or EN818-7. Grade 100 conforms to ASTM973 or NACM2010. Grade 43 is not suitable for heavy-duty mining use.
Do you provide proof load testing and breaking strength validation?
Yes. All production batches undergo proof load testing and breaking strength validation. Records are available on request. Marking on the hardware includes the working load limit and traceability details.
Can you supply chain connectors to match our mine cart rail profile?
Yes. Send us the rail section and bracket height, and we will confirm the correct flat sawtooth or arc tooth chain connector that fits your mine cart or conveyor frame.
What surface finishes are available for mining chains and shackles?
Available finishes include electrophoretic black, zinc plating, HDG (hot-dip galvanizing), and black oxide. Choose based on the site environment and corrosion resistance needs.
Do you supply Material Test Certificates with orders?
Yes. Material Test Certificates to EN 10204 3.1 are supplied with orders for rated metal components. Request them at the quote stage.
Can you ship all rigging components for a mining system together?
Yes. Goods can be held in our Qingdao warehouse for up to two months to consolidate shipments. All components for a single system ship together on one set of documents.
Do you offer custom marking or tonnage stamping?
