Types and Features of pulley wheel block
Crane pulley wheel functions
According to different functions, pulley wheels can be divided in crown block/ fixed pulley wheel and fall block/ moveable pulley wheel.

Therefore, they are coordinated to consist the pulley wheel block which can save energy and change the direction of movement at same time.
Crane pulley wheel materials
Based on different materials, pulley wheels can be classified into cast iron pulley wheel, cast steel pulley wheel, nylon pulley wheel, and aluminum pulley wheels.
Cast iron pulley wheel
Cast iron pulley wheels can be further divided into gray cast iron pulley wheel and nodular cast iron pulley wheel. The gray cast iron pulley wheel has the features of good performance, little wear to wire rope which is widely used in light working duty cranes. On the contrast, the nodular cast iron pulley wheels can stand more collision than that of gray cast iron and they are widely used in the heavy duty cranes.
Cast steel pulley wheel
Cast steel pulley wheel has the features of higher strength and toughness but less manufacturability. Due do the high hardness on the surface, cast steel pulley wheel may cause big wear damage to wire rope and are usually adopted by heavy duty conditions. As the large diameter pulley wheel is concerned, the cast steel pulley wheel are favored because the welding capability and comparatively light weight.
Nylon pulley wheel
Nylon pulley wheels are widely used on the cranes. Nylon pulley wheel has the features of light, wearable, and low stiffness.
Aluminum pulley wheel
