Abstract: Apparatuses, systems, and methods for determining and verifying operational states of fifth wheels. Certain methods for determining the operational state of the fifth wheel may include sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component movable to lock the fifth wheel to a kingpin of a towed vehicle and determining an end position of the movable component based on the magnetic flux. The end position of the movable component is then compared to a threshold position and an operational state of the fifth wheel is determined based on the comparison of the end position of the movable component to the threshold position.

Abstract: A weight distribution measurement system includes a portable measuring device configured to measure a linear distance and store a plurality of measurements. The portable measuring device is also configured to measure a first distance between a first location on a vehicle supported by an axle of the vehicle and a second location, wherein the first distance is measured prior to loading the vehicle. The portable measuring device is also configured to measure a second distance between the first location and the second location, wherein the second distance is measured after loading a vehicle. And the portable measuring device can measure a third distance between the first location and the second location, wherein the third distance is measured after loading a vehicle and after a weight distribution mechanism has been engaged, and then calculate the percent weight distribution over the axles of the vehicle using the portable measuring device and display the percent weight distribution.

Abstract: An attachment thimble is disclosed for attaching a rope shackle to a vehicle for towing, pulling, or other tasks. In one embodiment, the attachment thimble has spaced apart flanges and a mid-portion with a diameter less than the dimensions of the flanges. A through-bore is formed through the thimble from one flange to the other flange. The thimble is sized to be slid into a hitch receiver or disposed between mounting dogs of a D-ring mount. In one application, a rope shackle is formed into a loop by pressing the knot on one end of the shackle through the eyelet on the other end. The thimble is then disposed in the loop and the knot, eyelet, and thimble are slid into the hitch receiver of a vehicle until its through-bore aligns with holes in the receiver. A securement pin is then slid through the receiver and through the thimble to secure the rope shackle to the hitch receiver for use.

Abstract: A work holding device includes a first jaw piece having an elongated first connection member for connecting the work holding device to a support. The first connection member defines a first passage. A second jaw piece has an elongated second connection member positionable within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly movably couples the second jaw piece to the first jaw piece. The spindle assembly is configured to move the second jaw piece with respect to the first jaw piece to create a clamping pressure when an object is placed between the first jaw piece and the second jaw piece.
