Small Steel Blocks & Sheaves
Designed for small size wire rope and cable. Low carbon steel is used in the side plates while the sheaves are turned down using cold-rolled bar stock. The bearings are made from a combination of bronze and steel that is then oil impregnated to insure permanent self-lubrication. These bearings - specially designed for high load and medium speed applications - are then pressed into the sheaves. Al swivel eyes and hooks are drop forged. Each part is zinc-elctro galvanized and rivets are used to fasten block together. They are marked to comply with NIDA-SIDA standards. Shown are single and double patterns available. We encourage you to contact us for custom applications.

DO NOT EXCEED WORK LOAD LIMIT OR 20% OF THE PRODUCT'S BREAK STRENGTH.

 

BLOCK WARNING: The work load limits shown indicate the maximum load that should be exerted on the block at any time! This load value may be different from the weight being lifted or pulled by a loading or hoisting system. It is necessary to determine the total load being imposed on each block in the system to properly determine the block to use (for instance, a single sheave block being used to change load line direction can be subjected to total loads greatly different from the weight being lifted or pulled!).
