PCA-1273 Stainless 2 Sheave Pulley 4 inch

Description

This stainless steel swing side snatch block features two lightweight 4 inch diameter deep groove aluminum sheaves, with stainless steel plates that swing open to install rope. Sintered bronze bushings on stainless steel shaft provides 98% efficiency. Using one double pulley (positioned at the load) with a single pulley, you can quadruple the pulling power of the winches. With two double pulleys, an amazing 5 tons of force can be exerted on a load (using the PCW5000).

The middle plate has a hole at the bottom, allowing you to attach the end of the rope with a carabiner when necessary.

Use the 70 kN steel locking carabiner (PCA-1701) to anchor the snatch block to a polyester sling.

Ideal rope diameter: 1/2 inch.

The NEWTON is the International System unit for force; it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one meter per second squared. --- The WORKING LOAD LIMIT (WLL) is the maximum load which should not be exceeded under any condition. --- The MINIMUM BREAKING STRENGTH (MBS) is observed during a destructive test. You should divide it by an appropriate safety factor.
