Double Sheave Block Conductor Stringing Blocks For Changing Line Suitable

Core Design Features

• Duplex chromium-plated steel sheaves for smooth cable guidance
• Integrated load-bearing axle with double-row tapered roller bearings
• Hot-dip galvanized steel frame with 360° swivel base
• Working Load Limit: 2-15 tons (color-coded by capacity)
• Compatible with 3/8" to 3/4" diameter conductors
• Safety factor: 4:1 per EN 13414-1 standard

Operational Advantages
