Crane Hook Block
INTRODUCE :

Kingrail Parts has developed a series of new blocks and tracks based on the latest requirements and technology FEM 1001 and DIN standards 15020.

 

In all cases, the security at the face of damage is higher than the requirements of the FEM standard. Suspension (hook, cross axle, nut) meets the DIN standard 15411. The hook complies with the DIN standard 15401 and 15402, which is made of STE355 -level forged steel (G -grade, DIN standard 15400). If necessary, you can use alloy 34 CR MO 4, 34 CR Ni Mo 6 and 30 CR Ni Mo 8 (S, T, V Grade).

 

All linked hooks are equipped with safety bolts to prevent them from being separated from sling. They can be equipped with an anti -rotation system, which can be easily installed without using tools; this can keep the hooks stable. The pulley is made of rolled steel, designed and manufactured by Kingrail Parts, and is equipped with a double -cylindrical roller bearings, which is perfectly located with the special holder. These bearings are lubricated by the lubrication point, each pulley is located at the end of the axle, and properly prevent any possible knocks.

 

Pay special attention to the shape of the throat when constructing a pulley. The bottom radius (DIN 15601 (R = 0.525 D)) greatly extends the service life of the cable. If the cable is placed correctly in the throat of the pulley, the service life will reach the maximum value. The throat can extend the service life of the cable and can be provided according to the requirements. Due to the type of bearing used, the distance between the pulleys (four or more pulleys and the boat) is very small.

SPECIFICATIONS :
