INDUSTRIAL PULLEY BLOCKS
Industrial Grade Construction,
Reliability & Performance
Ronstan’s Industrial Pulley Blocks offer a high quality, reliable solution for
a myriad of applications. Full stainless steel housings and attachment
fittings provide ultimate durability, long service life and resistance to harsh
environments. Self-lubricating acetal polymer sheaves running on polished
stainless steel races perform equally well with dynamic loads and high static
loads, and an alloy sheave option is available for use with wire rope. Ronstan
Industrial Blocks are load rated and are backed by a full factory warranty.
Swivelling and pivoting shackle head
Allows easy attachment and correct alignment of the pulley block. Shackle pins are drilled
for use of security wire. The option of shackle with clevis pin and retaining ring is available in
Series 75 - order as RZxxxxC. Provides tool-free attachment and removal.
Removable becket to suit pre-spliced lines
Pre-spliced lines are neat, compact and provide greater security and strength than knotted
terminations. Beckets on all Ronstan Industrial Blocks are removable to accommodate the
use of pre-spliced lines.
Simple and secure rope holding
Blocks fitted with cam cleats provide a simple means of holding the rope. Just pull the rope
through the spring-loaded jaws, which prevent the rope from slipping back. Flick the rope up
and out of the jaws to release. A stainless steel eye strap keeps the rope in position ready for
re-cleating.
