What is a Hook Block?

The hook block is a crucial lifting component specifically designed for industrial heavy-duty applications. It is composed of multiple components such as pulleys, pulley shafts, hook bodies, nuts, and crossbars, and is the core lifting unit of various cranes. The working level is at M5 or above.

The hook body is forged from 35CrlMo. The forging of the hook body should comply with GB10051.4-10 and GB6067-85 regulations. The surface is smooth, without wrinkles, grooves, or surface defects such as cracks. The hook body undergoes 100% UT flaw detection and surface magnetic particle flaw detection.

The pulleys are hot-rolled from Q355B plates.

The environmental temperature ranges from -40 degrees to 55 degrees.

The paint color is black and yellow, with a total dry film thickness of the paint ≥ 180 um.
