Features and Benefits
The drill stem lift mechanism uses a four-part reeving system of high-strength cable and pulley blocks and sheaves. Both hanging block type pulleys and overhead supported sheaves can be provided. Attachment of blocks to the crosshead and tower structure is achieved through the use of hanger plates which are custom designed for individual applications.
The guide sheave or the crown sheave is available with an adaptation for the system to indicate “in-drum” tool position. This system is compromised of a NEMA 7 box, a local indicator mounted on the hoist console, special probes and drilling on the guide sheave.
