The invention relates to a device and a method for reaming a flight gap of a drill flight of a drilling tool, comprising a base carriage which can be displaceably mounted along a mast of a drilling apparatus, a reaming element which is configured to engage in the flight gap of the drilling tool, wherein soil material adhering to the drilling tool can be scraped off by the reaming element upon rotation of the drilling tool, and a support arm on which the reaming element is held and which is mounted movably relative to the base carriage between a retracted position, in which the reaming element is spaced apart from the drilling tool, and a reaming position, in which the reaming element engages in the flight gap for reaming soil material. According to the invention, it is provided that the support arm is pivotably mounted between the retracted position and the reaming position about a pivot axle which is oriented substantially parallel to a drilling longitudinal axis of the drilling tool, that the support arm is additionally mounted on the base carriage in a direction parallel to the drilling longitudinal axis of the drilling tool, so as to be deflectable from a basic position, and that the support arm is resiliently held in the basic position by means of a bias spring.

A unique carbon fiber structure that achieves the strength and durability of steel tower alternatives at 90% less weight and a lower total installed cost, providing affordable carbon fiber telecommunication towers that are engineered for peak strength to weight performance wherein the carbon fiber structure is a vertical elongated tower body of decreasing area with an internal installation shaft provided therein to house one or more radio base stations wherein the tower may be made of multiple cylindrical or cone shaped hollow segments with a shaved upper portion whereby the segments are created with carbon fiber and fiberglass hoop windings.

An off-gas conditioning system includes a source of off-gas, at least one testing port, in communication with the source of off-gas wherein the testing port is connected to a meter capable of testing at least one metric selected from the group consisting of temperature, pressure, flow rate, and humidity. A first vapor-liquid separator in communication with and downstream of the source of off-gas, a second vapor liquid separator in communication with and downstream of the first vapor liquid separator, wherein at least one of the first or second vapor-liquid separators includes a heat-exchanger for cooling the off-gas, and wherein at least one of said first or second vapor liquid separators includes a particulate filter for removing particulates from the off-gas. at least one testing port, downstream of the second vapor-liquid separator in communication with at least one analyzer for analyzing said off-gas for specific chemical compounds.

A wheeled vehicle and core saw system has a chassis, a first sub-frame, a core saw attached to the first sub-frame, and a second sub-frame attached to the chassis frame and attached to the first sub-frame. A selectively engageable bearing may be disposed between the second sub-frame and the chassis frame that facilitates movement between the second sub-frame and the chassis frame. The second sub-frame may be moveable with respect to the chassis frame and a water tank.

A mobile drilling machine may include a drilling mast including a mast frame. The mobile drilling machine may further include a rotary head movably mounted on the mast frame, the rotary head controllable to rotate a drill string at a desired drill string rotation speed. The rotary head may further be controllable to move up and down the mast frame at a desired drill string feed speed. Additionally, the mobile drilling machine may include a joystick movable to control the desired drill string rotation speed and the desired drill string feed speed of the rotary head. A controller of the mobile drilling machine may be configured to receive a current desired drill string rotation speed and drill string feed speed information from the joystick and lock the current desired drill string rotation speed and the desired drill string feed speed upon activation of a switch mechanism.

A bolting and drilling system comprising a vehicle, a gantry mounted to the vehicle, a boom assembly having a first end mounted to the gantry and a second end having a first quick connector and a second quick connector. The system includes a bolter assembly connectable to the first quick connector, wherein the bolter assembly comprises a stinger, a drill and a bolter for stinging, drilling and bolting a roof of an underground mine. The system includes a drill feed assembly connectable to the second quick connector, wherein the drill feed assembly comprises a drill for drilling a rock face of a heading. The drill feed assembly is longer than the bolter assembly.

The present invention relates to a hollow boring auger for use for poles, including a first and second mounting part moveably connected, one to the other, to substantially encircle the pole. A first and second auger part are also included, correspondingly attachable to the first and second mounting part, to substantially encircle the pole, A rotation apparatus associated with the mounting parts and the auger parts is included such that in use the auger parts can be rotated about the pole to bore a hollow trench about the pole. The invention also relates to a method of use.

A core drill apparatus includes a swing arm pivotably couplable to a mobile platform and a core drill carried by the swing arm. The core drill being movable via the swing arm between a stowed position and a deployed position with respect to the mobile platform. An excavation rig incorporating the same is also provided.

A vehicular auger implement. The implement is configured to be operated by a single operator and comprises an auger having a bit. The implement includes a four bar linkage comprising a first bar, a second bar, a third bar, and a fourth bar. The first bar is coupled to each of the second bar and a hydraulically actuated arm. The auger is operably coupled to the fourth bar. The four bar linkage is configured to convert a rotational motion of the second bar to a vertical motion of the auger. A vehicle to which the auger implement is coupled is configured to remain stationary while a hole is bored using the vertical motion of the auger.
