Crown Block
Crown Block
Our crown block is built in accordance with API 4F and 8A, with the certificate of authority to use the official API monogram. It also meets the requirements of industry standard SY/T5527.
Being quenched, the sheave groove is anti-abrasive, resulting in longer service life. A wireline guide device is equipped to prevent the wireline from being out or falling off. In addition, our crown block is equipped with anti-vibration wood and protection net, sand block and assistant block, as well as gin pole for block servicing. The sheaves of crown block and mated traveling block are interchangeable.
