Overview

The KUPO CHC-6.3/19.1 is a 6.3 x 19.1 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 chain sits in the useful middle range between the 4.0 mm 250 kg chain and the 7.1 mm chain used on larger hoists. It is the right match for half-ton RIGPRO applications where the chain needs more capacity without moving to the largest hoist family.

Key Features

• EN 818-7 compliant Type DT construction matches the baseline standard for power-driven hoist chains.
• 50.0 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.
