The KUPO CHC-7.1 is a 7.1 x 20.2 mm Grade 80 alloy load chain for RIGPRO hoists, manufactured from chromium-molybdenum alloy and finished in black phosphate for corrosion resistance and a low-profile entertainment look. It is an EN 818-7 Type DT chain for power-driven hoist use, with periodic embossing for traceability and identification.
Why It Matters
This is the workhorse RIGPRO chain size for 750 kg through 2000 kg hoists. It is made for heavier entertainment lifting where durability, traceability, and correct chain-to-hoist matching are not optional details.
Key Features
EN 818-7 compliant Type DT construction matches the baseline standard for power-driven hoist chains.
63.0 kN minimum breaking force supports the rated hoist families that use this chain size.
HV 550 minimum hardness and 12 percent minimum elongation at break support controlled lifting-chain performance.
Black phosphate finish helps resist corrosion and keeps the chain visually discreet in entertainment rigs.
Friction Clutch: Yes, located outside the load path
Positioning: No Micro Switch Positioning (MSP)
Applications
Use as load chain for compatible RIGPRO chain hoists in entertainment rigging, touring systems, theatres, venues, broadcast studios, and professional overhead lifting applications.
Compatibility
RD-750/1000 + RH-1000/2000
Frequently Asked Questions
Can I substitute a different chain size in the same hoist
No. Hoist load chain must match the hoist design, pocket wheel, rating, and manufacturer requirements. Use the chain size specified for that hoist family.
Why does the chain need periodic embossing
Periodic embossing supports traceability and identification, which is required by EN 818-7.
Is this chain for hand lifting or power-driven hoists
The source identifies it as an EN 818-7 Type DT chain for power-driven hoists.
