A completion system and method adapted for use in wells having long lateral boreholes includes a mast assembly, a pipe handling mechanism, a pipe arm, a pipe tub, a pump/pit combination skid, a rig carrier, and a control system. The mast assembly can extend in a generally vertical direction, e.g., perpendicular to the rig carrier and/or the earth's surface, such that the rig can be placed directly adjacent to a wellbore, and the top drive or a similar drive system can be engaged with and move along the mast while remaining above the wellbore. The top drive can be engaged with a support fixture that resists torque and rotation during operation. The support fixture can in turn be engaged with the mast to transfer torque forces to the mast while being vertically movable along the mast to enable positioning of the top drive.

In an automotive construction machine, with a machine frame (4) with preferably vertically arranged lateral outer walls (5), a milling drum (6) mounted in the machine frame (4) for working a ground surface or traffic surface (8), and with an operator's platform (10), it is provided that the operator's platform (10) is moveable on the machine frame (4) transversely to the direction of travel, and is moveable outwards beyond the lateral outer walls (5) of the machine frame (4), that the machine frame (4) is provided with a guide (18) for the operator's platform (10) acting transversely to the direction of travel, and that the guide (18) projects laterally either not at all or just slightly beyond the outer walls (5).

A work machine comprising a main body and a cab riser. The cab riser includes a cab and a frame comprising a first plate to contact a second plate provided on the main body in a first position which the cab is uprightly positioned on the work machine. The first and the second plate are coupled together to sandwich a key plate in the first position, the key plate being disposed in a space created by a first recess on a lower surface of the first plate and a second recess on an upper surface of the second plate, the second recess being aligned with the first recess vertically in the first position, and the key plate includes a first contact surface as a slope surface and a top surface being adjacent to the slope surface in the cross sectional view of the key plate.

Provided is a first robot including: a machine readable medium storing instructions that when executed by the processor of the first robot effectuates operations including: executing, with the processor of the first robot, a task; and transmitting, with the processor of the first robot, a signal to a processor of a second robot during execution of the task when its power supply level reduces below a predetermined threshold; and the second robot including: a machine readable medium storing instructions that when executed by the processor of the second robot effectuates operations including: executing, with the processor of the second robot, the remainder of the task upon receiving the signal transmitted from the processor of the first robot; and wherein the first robot navigates to a charging station when its power supply level reduces below the predetermined threshold and wherein the first robot and second robot provide the same services.

A cabin support deck for supporting a cabin of a construction machine on the underside of the cabin includes a frame member and a mounting portion. The frame member includes a proximal segment at which the frame member is supported, a distal segment, a left side segment, and a right side segment. The distal segment has a first structure having a first lateral dimension. The proximal segment has a second structure having a second lateral dimension which is greater than the first lateral dimension. At least one of the proximal side sections of the left side segment and the right side segment has the second structure, and the other portions of the left side segment and the right side segment have the first structure.
