It is assembled on the derrick. Together with travelling block, hook and drawworks, it can complete the operation of drill lifting and lowering.

Our crown block delivers reliable performance at the top of the derrick, engineered to withstand the extreme loads and continuous operation of modern drilling. Each sheave is precision-machined from high-strength alloy steel with hardened grooves to extend wire rope life, while heavy-duty roller bearings ensure smooth rotation under full load. The rugged fabricated housing provides secure mounting to the derrick structure while protecting sheaves from environmental exposure. Designed for easy maintenance with centralized lubrication points and accessible bearing fittings, our crown blocks are available in various sheave configurations to match any rig’s hoisting requirements.
