Abstract: A gearbox guide assembly is provided. The guide assembly includes a guide plate. The guide assembly is configured to guide a movement of a gearbox along a mast of a machine. The gearbox guide assembly also includes a support assembly associated with the guide assembly. The support assembly is configured to couple to the mast. The support assembly is removably attachable to the guide assembly through mechanical fasteners. The support assembly includes a plurality of wear pad assemblies attached to the support assembly. Each of the plurality of wear pad assemblies includes a wear pad configured to contact the mast. Each of the plurality of wear pad assemblies also includes a key element removably coupled along one edge of the wear pad by mechanical fasteners. The wear pad is accessible for removal thereof by decoupling the key element associated therewith.

Abstract: A pipe handling system for a platform based drill includes a drilling platform with a frame structure having a first end, a second end opposite the first end, and first and second opposite sides. A mast is supported on a pivotal connection to the platform permitting the mast to be pivotally adjusted to a negative drilling angle whereby an upper portion of the mast leans in a first direction extending toward the first end of the frame structure and away from the second end of the frame structure. The mast includes a length direction and has an open cross-section with a concave side facing in the first direction and a convex side facing in a second direction opposite to the first direction. A pipe handling unit mounted to the concave side of the mast is configured to support a drill pipe within the mast when the mast is pivotally adjusted to the negative drilling angle.

Abstract: A system for disassembling components of a drill string includes a primary wrench, a secondary wrench, and a bit removal basket. The primary wrench has a pair of jaws in which at least one of the jaws is moveable in relation to the other. The secondary wrench is disposed at a position lower than the primary wrench and is configured to define a pair of beveled faces that are adapted to restrict a rotational movement of at least one component of the drill string. The bit removal basket is disposed at a position lower than the secondary wrench. The bit removal basket is configured to define an opening therethrough. A shape of the opening is configured to correspond with profiles of at least two types of drill bits, one of the at least two types of drill bits being present for use in the drill string.
