A drill rig includes a base, a drill tower extending from the base, a drill pipe coupled to and supported by the drill tower, and a driving mechanism coupled to the drill tower that moves the drill pipe relative to the drill tower. The driving mechanism includes a rack and a plurality of pinions that engage the rack. The drill rig also includes an adjustment mechanism coupled to the driving mechanism, the adjustment mechanism including a plurality of rollers and an adjustment component that moves the plurality of rollers simultaneously toward the pinions to contact the rack.

Gear backlash adjustment mechanism

An industrial machine includes a frame supporting a boom having a first end and a second end opposite the first end, an arm movably coupled to the boom and including a first end and a second end, an attachment coupled to the first end of the arm, a conduit extending from the frame to a position adjacent the attachment, a first member coupled to the boom, and a second member spaced apart from the first member. The first member supports a portion of the conduit as the arm moves relative to the boom. The second member supports a portion of the conduit as the arm moves relative to the boom. The second member is movable relative to the first member.

Conduit support system

A pick holder for a roll sizer, the roll sizer including at least one roll drum defining a drum axis, the roll drum rotating about the drum axis. The pick holder includes a base and a shoulder. The base includes at least one hole for receiving a fastener for removably coupling the pick holder to the roll drum. The shoulder is coupled to the base.

Pick holder

A reel system includes a reel having a rotational axis, the reel including a plurality of ledges spaced radially from the rotational axis, the ledges defining a stepped configuration along an interior surface of the reel. The reel system also includes a first clamp having a first width and a second clamp having a second width greater than the first width, wherein the first clamp and the second clamp engage the plurality of ledges as the reel is rotated.

Reel with stepped configuration

A moveable shaft assembly including a frame, a first shaft, and a first drive assembly. The frame includes a first support wall and a second support wall opposite the first support wall. The first shaft includes a drive end and a support end and defining a first axis therebetween. The first shaft extends between the first support wall and the second support wall. The first drive assembly rotates the first shaft about the first axis, and the first drive assembly is coupled to the drive end of the first shaft. The first shaft and first drive assembly are moveable relative to the frame in response to a reaction force acting on the first shaft in a direction oblique or transverse to the first axis.

Moveable shaft assembly

A retainer assembly for securing a bearing relative to a shaft in a first axial direction. The retainer assembly includes a collar, a lock ring, and a retaining nut. The collar includes a first portion, a second portion, and a bore extending through the first portion and the second portion. The first portion includes external threads, and the second portion includes an internal recess extending circumferentially around the bore. The lock ring is located within the internal recess such that the lock ring is positioned between the second portion of the collar and the shaft and is removably coupled to the shaft. The retaining nut includes internal threads that threadingly engage the external threads of the first portion.
