Stainless Steel Hoisting Tackle Pulley Hoist Sheave Suitable For
Various Applications
A heavy iron pulley is a device used to lift and suspend heavy
objects, usually made of iron or other metallic materials. They are
widely used in places such as construction sites, factories, docks
and shipyards to lift cargo, equipment and other heavy items. The
following is a general introduction to heavy rail blocks:
Construction and how it works: A heavy iron block usually consists
of one or more wheels, which are mounted on a sturdy metal frame.
The weight is tied to the block by a rope, chain or wire rope, and
then the block is moved along the hook or suspension device by
manual or mechanical means, so as to achieve the lifting and
suspension of the weight.
Load-carrying capacity: The load-carrying capacity of heavy iron
blocks varies depending on their design and specifications, and can
accommodate objects of various weights and sizes. Larger lifting
iron blocks usually have a higher carrying capacity and can handle
heavier items.
