Product Description

Product Description

The frame of the crown block is made with high strength steel material. Working pulley block are set slantingly to counteract the torsion of sheave and make side board of traveling block face to derrick. The pulley groove is undertaken middle-frequency quencher so as to extend operating life of sheaves. Working sheave are assembled with double-conic bearing, wherein each bearing has its individual lubricating channel.Rope bar are provided to prevent the wire rope from crossing or failing out the groove. The Crown block is also equipped with wooden buffer and protection net to prevent bump. It is equipped with derrick crane as well for repairing the crown block. Sand sheaves and auxiliary sheaves Assy can be provide as the requirement climbing assistor and falling-proof device can be installed according to various requirements. Besides, sheaves and bearing are interchangeable with its matched crown block.

Features:

1. The crown block is designed and manufactured in accordance with API4F and 8C standard, and have the right to use API symbol.

2. Standard meets SY/T5527 requirements.

3. After quenching pulley groove is anti-abrasive and has long service life.

4. Stick and groove for rope will prevent wireline from droping out.

5. Equipped with anti-collision cushion board and protective screening.

6. Lifting plate for maintenance of crown block.

7. Sand pulley and subsidiary assembly pulley shall deploy according to customer’s requirements.

8. Pulley and bearing of Crown block can interchange with allied travelling block.

Note: Customized design and configuration is available to meet different requirements...
