摘要： A fastening system that comprises a fastener and a single tool that provides both snugging torque and final tensioning to the fastener assembly, from a single side, with a single operator, with no torque feedback. The fastener comprises a nut and a bolt with a head and a shank extending axially from the head. The shank has at least one threaded portion and at least one splined portion, the splined portion defining the end of the bolt. The splined portion remains connected to the threaded portion after final tensioning. The tool comprises a first socket and a second socket, wherein the first socket is engaged with an outer surface of the nut and the second socket is engaged with the splined portion on the fastener. Snugging torque and final tension are both controlled by the tool.

摘要： A drive track is for a wheel train for mobilizing a paving vehicle upon a ground surface, the wheel train including a drive wheel and a bogie wheel. The track includes an endless body disposable about the wheel train and having a driven portion engageable by the drive wheel such that the drive wheel circulates the track about the wheel train. A generally annular rail portion is connected with the drive portion and has a continuous inner circumferential surface contactable with the bogie wheel, such that the bogie wheel rolls along the inner surface, and a continuous outer circumferential surface contactable with the ground surface. The rail portion supports the bogie wheel above the ground surface such that when the track circulates about the wheel train, a distance between the bogie wheel axis and the ground surface remains substantially constant as the bogie wheel rolls along the rail inner surface.
