A quick disconnect Kelly bar system is provided. In use, a construction attachment includes a quick disconnect mounting plate for connecting the construction attachment to a hitch of a construction machine. A pivotable coupling assembly is connected to the quick disconnect mounting plate. Additionally, an extendable mast is connected to the pivotable coupling assembly at a first end of the extendable mast, and to a headblock structure at a second end of the extendable mast. Further, a Kelly-bar assembly is connected to the headblock structure.

A vehicle support structure, which in petroleum wellsite operations is commonly called a rig mat or a ground stabilizing mat, includes: a main body including an upper surface, an underside, a front end and a rear end, the main body defining a planar structuring with a thickness; a front pad coupled to the main body and positioned adjacent the front end; a rear pad coupled to the main body and positioned adjacent the rear end, the front pad and the rear pad each configured to be moveable between a supporting position protruding from the underside of the main body and a retracted position in plane or retracted from the underside; a front pad drive mechanism for the front pad, the front pad drive mechanism configured to drive the front pad to move between the supporting position and the retracted position and to move the front pad forward and backwards and side to side relative to the main body; and a rear pad drive mechanism for the rear pad, the rear pad drive mechanism configured to drive the rear pad to move between the supporting position and the retracted position and to move the rear pad forward and backwards and side to side relative to the main body, the front pad and the rear pad being configured to operate to support the main body in an elevated position relative to a ground surface and configured to move the main body forward and backwards and side to side relative to the front pad and the rear pad and over the ground surface. In use as a rig mat, a method for well site operations includes: placing the rig mat at a position on a first well site; positioning a rig on the rig mat; and adjusting the position of the rig mat while the rig remains supported on the rig mat such that the rig is centered on a wellhead of the well site.

The invention relates to an assembly (1) for forming a mast for guiding a drill drive in an HDD machine. The assembly comprises a mast body (10) with a generally U-shaped cross-section, a mast cover with a recessed surface (21), a set of two or more racks (30), first connecting means (24) for connecting the racks releasably to the mast cover and second connecting means (44) for connecting the racks releasably to the mast body. The racks together with the mast body and the mast cover in assembled state form a mast with a substantially closed contour.

A drilling machine includes an inclination-based levelling system. The drilling machine includes a frame with front and rear portions, and a plurality of support jacks including a pair of rear jacks proximate the rear portion of the frame and a front jack proximate the front portion of the frame. Each jack is extendable and retractable. The drilling machine also includes a sensor configured to monitor and transmit sensor data, the sensor data including at least one of a roll of the drilling machine and a pressure. A controller operatively associated with the sensor, is configured to calculate a volume of debris to be produced during an operation of the drilling machine, to select a machine height setting based on the calculated volume of debris, and to extend and retract the plurality of support jacks according to the selected machine height setting.

An apparatus, a method for positioning a rock drilling, and a rock drilling rig is provided. The rock drilling rig includes a mobile drilling platform and a drilling mast connected to the drilling platform. The drilling platform is levelled vertically before initiating drilling. The apparatus determines the needed vertical levelling requirement. The levelling causes displacement of a drilling tool line passing through a drilling tool. The apparatus estimates the displacement and provides aid for the operator to position the drilling platform in order to compensate for the estimated displacement distance.

Construction equipment is provided that can include: a transport assembly operably supporting a platform, the platform having a leading edge opposing a rearward edge, the leading edge associated with a first direction of the transport assembly, and the rearward edge associated with a second direction of the transportation assembly; an operator cab above the platform and aligned closer to the leading edge than the rearward edge; an engine above the platform and aligned closer to the rearward edge than the leading edge; and a boom pivotably attached above the platform closer to the rearward edge than the leading edge, the boom being movable between a first position fully extended and a second position fully raised. Utility line pole placement and/or removal construction methods are provided that can include extending an extension assembly having a banana boom from a transport assembly to couple with a utility line pole.
