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.

An adjustable drilling rig is provided for drilling and installation of foundational micropile matrices in difficult to access locations. A platform and separately adjustable legs are provided to level the platform. Arms and a crossbar mount to the legs, and each includes a bushing slidably mounted and moveable there along. A mast is slidably attached to the crossbar bushing through a mounting plate. The mast carries a drill head to which a drill will be attached. Various adjusters are mounted to bushings, mounting plate and other components of the adjustable drilling rig and are independently and selectively activated to adjust the drill head translationally along the X-, Y- and Z-axes and rotationally about the X- and Y-axes to achieve five degrees of freedom in five planes. The entire adjustable drilling rig is provided in two frames for easy transport to remote work sites and may be assembled without complex tools.

A system, apparatus, and method for leveling a borehole or blasthole drilling machine, or portion thereof, provided over a drilling site can implement a ground contact detect phase or operation, a first coarse leveling phase or operation, a lowering phase or operation, and a fine leveling phase or operation. The phases or operations can be based on or responsive to signals from sensors of the drilling machine. The phases or operations can involve changing length of one or more of the jacks of the drilling machine when the drilling machine is positioned over the drilling site.

Embodiments of the present disclosure relate generally to underground horizontal directional drills and, more particularly, to aspects of drill operation, ground anchoring, and operator assistance features. In some embodiments, a drill is provided that includes an anchor assembly and/or a rear stabilizer that may pivot relative to a carriage frame of the drill. In other embodiments, a roller bearing system that permits the carriage to translate along the carriage frame is provided. In still other embodiments, rests to support the drill rod during makeup and breakout are described.

An anchoring device for a horizontal directional rig is provided. The anchoring device uses vibrations from a motor to drive an anchor into the ground in a more efficient manner than traditional stake down systems. The vibrating motor is mounted to a stake down carriage. The oscillations from the motor allow the steel anchor to penetrate the ground with a small axial load and therein allows greater surface and holding force.

A system and a method are for positioning a drilling rig arranged to drill in a ground. The system has a positioning jig including at least one coupling portion; a drilling rig including at least two coupling portions; and at least two anchoring elements including an upper coupling portion and a lower coupling portion. The lower coupling portion of the anchoring element is arranged to be releasably fixed to the ground. The upper coupling portion of the anchoring element is arranged to be connected to the coupling portion of the positioning jig and to the coupling portion of the drilling rig, so that the upper coupling portion of the anchoring element can optionally be connected to the positioning jig or the drilling rig.

An anti-jam control system for mobile drilling machines is disclosed. The anti-jam control system may include a method for automatically clearing a jam during an automatic drilling mode of a mobile drilling machine including a drill bit mounted on a drill string. The method may include: monitoring a feed rate of the drill bit during the automatic drilling mode; and automatically initiating an anti-jam operation when the feed rate is below a predetermined feed rate threshold.

A levelling assembly is provided, for levelling an upper carriage assembly of a machine with respect to an undercarriage assembly having a first track roller frame and the second track roller frame. A levelling body is rotatably coupled to the first track roller frame and the second track roller frame and defines a first side and a second side laterally opposite to the first side. The levelling assembly includes a first pair of fluid actuators for movably coupling first side of the levelling body with the first track roller frame and a second pair of fluid actuators for movably coupling second side of the levelling body with the second track roller frame. The first and the second pair of fluid actuators move the levelling body between a fore tilted position and an aft tilted position relative to the first and the second track roller frames.

Skid-steer loader attachment assemblies configured to perform earth augering are provided. The attachment assemblies can include a pair of outriggers. Methods for performing earth augering using a skid-steer are also provided. The methods can include extending dual outriggers from a boom assembly of a skid-steer to engage substrate; and extending an earth auger into the substrate from an auger assembly that is operably engaged between the dual outriggers. Skid-steer loader and attachment assemblies configured to perform earth augering are also provided. Boring assembly coupling assemblies are also provided.

The invention relates to an earth working apparatus having an undercarriage which is designed as a running gear, and an upper carriage which is supported in a rotatable manner on the undercarriage and has a driver's cab as well as a drive motor for the undercarriage. According to the invention, between the undercarriage and the upper carriage an extension segment is arranged, through which a vertical distance between the undercarriage and the upper carriage is extended. On the extension segment between the undercarriage and the upper carriage a support means for tilt protection is mounted. The invention furthermore relates to a method for earth working with an earth working apparatus of such type.
