Crane Hook Block
Description:
A crane hook block typically consists of hook, safety latch, pulley, and steel wire rope. It can be configured as a single hook or a ramshorn hook, either a forged or laminated hook, with lifting capacities ranging from 5 tons to 500 tons. The hook block is a standard component found in most cranes and lifting equipment.
Forged Single Hook:
-
The forged hook is manufactured using DG20 (DG20Mn) material for enhanced durability.
-
Each hook is equipped with a safety latch to securely prevent the load from unintentionally unhooking during operation.
-
The pulley diameter-to-wire rope diameter ratio exceeds 20, ensuring optimal service life for the rope.
-
All pulleys are fitted with protective covers or devices to prevent the rope from slipping out of the groove, ensuring safe and efficient operation.
Forged Double Ramshorn Hook Block:
-
The forged ramshorn hook is crafted from DG20 (DG20Mn) material, ensuring exceptional strength and durability.
-
The double hook design provides optimal stress distribution, allowing for the efficient utilization of the hook body material.
-
Each hook is fitted with a safety latch to prevent the load from unintentionally disengaging.
-
The ratio of pulley diameter to wire rope diameter exceeds 20, which contributes to the extended service life of the rope.
-
A protective pad is incorporated at the hook opening to prevent damage from friction with the spreader, thereby enhancing the hook's longevity. This protective pad can be easily replaced when worn.
Laminated Ramshorn Hook Block:
-
The hook is a laminated gantry hook, riveted together using Q345-B steel plates, with a protective pad at the hook mouth.
-
The protective pad at the hook mouth safeguards against damage caused by friction with the spreader, prolonging the hook's service life. The pad can be replaced when it becomes damaged.
-
The laminated double hook is designed for enhanced safety and reliability, ensuring it does not break suddenly under load.
-
All hooks feature a safety latch to prevent the load from unhooking.
-
The pulley diameter-to-wire rope diameter ratio exceeds 20, ensuring the longevity of the rope.
-
All pulleys are equipped with protective covers or devices to prevent the rope from slipping out of the groove.
-
Laminated hooks are commonly used in the lifting of heavy loads, such as ladles, offering robust performance in demanding applications.
National Standard Testing Center:
-
We have national standard testing center lab with testing methods: non-destructive testing, metallographic analysis, mechanical testing and chemical analysis, mainly testing and control of the crane parts, raw materials, product welding quality, etc.
