Advantages of Double Horizontal 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 Working Load
Double Horizontal Blocks allow full 180 degree of horizontal rope exit 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.
