Sheave Block
Guiding with DSRB wire rope sheave blocks for Pfaff winches.
The dynamic all-rounder with variable rope and sheave diameters and cable deflections of up to 180 degrees moves loads with ease and absolute reliability. The models offered here cover load capacities from 500 kg to 4500 kg depending on model and deflection angle (the complete DSRB S range goes up to 8 tonnes).
Typical for Pfaff is the high standard of quality: the sheave block for manual and powered operation is equipped with grease-filled, sealed ball bearings as standard. A carefully coordinated system of application-specific cable diameters and matching turned precision cable groove ensures that the unit is also wear-free.
