Crown Block of Oil/Gas Drilling Rig with Pulley and Rope
Technical Features:
• The sheave grooves are quenched to resist wear and extend its service life.
• The kick-back post and rope guard board prevent the wire rope from jumping out or falling out of the sheave grooves.
• Equipped with safety chain anti-collision device.
• Equipped with a gin pole for repairing the sheave block.
• Sand sheaves and auxiliary sheave blocks are provided in accordance with users’ requirements.
•The crown sheaves are completely interchangeable with those of its matching traveling block.
