Advantages of Swivel Blocks
High Strength to Weight Design
Alloy steel sheave with machined web profile reduces unnecessary weight and provides highest strength to weight ratio.
High Sheave-to-Rope Ratio
Minimum 16:1 sheave outside diameter to rope diameter ratio to reduce rope bending stress and increase rope life.
High Versatility
Swivel blocks self-align to ensure proper cable routing to maximize rope life.
High Efficiency Bearing
Sheaves utilize either ball bearings or cylindrical roller bearings for reduced friction, smooth motion, and lifetime lubrication.
