Abstract: A wheel grid includes a crossbar configured to be coupled to a boom of a tow vehicle, the crossbar extending in a lateral direction from a centerline to a distal tip, and an L-arm rotatably coupled to the crossbar at a proximal end of the L-arm and configured to rotate about a rotation axis from an engaged position to a stowed position. As the L-arm rotates from the engaged position to the stowed position, the L-arm intersects with a line parallel to the rotation axis and passing through the distal tip of the crossbar. In the stowed position, an entirety of the L-arm is positioned closer than the distal tip of the crossbar to the centerline of the crossbar in the lateral direction.

Abstract: A wheel grid includes a crossbar configured to be coupled to a boom of a tow vehicle and including a distal tip. The wheel grid further includes an L-arm rotatably coupled to the crossbar at a proximal end of the L-arm and configured to rotate from an engaged position to a stowed position. As the L-arm rotates from the engaged position to the stowed position, a distal portion of the L-arm intersects with a vertical line passing through the respective left or right distal tip of the crossbar. In the stowed position, the distal portion of the L-arm is positioned laterally inward relative to the distal tip of the crossbar.

Abstract: A wheel grid includes a crossbar configured to be coupled to a main boom of a wheel lift tow vehicle; two L-arms, each coupled to the crossbar at a respective pivot point and including an extension member and a wheel brace member; and a crossbar end coupled to each end of the crossbar and including a cantilevered portion, the crossbar ends each configured to engage a tire of a towed vehicle. The L-arms are configured to rotate into a stowed position in which each L arm is positioned under one of the cantilevered portions.

Abstract: A counterweight for a vehicle includes a housing configured to be coupled to the vehicle. The housing defines an internal cavity configured to selectively receive one or more weights. The housing is configured to be selectively repositionable relative to the vehicle.

Abstract: A counterweight system includes a bracket and a counterweight. The bracket includes a base configured to couple to a vehicle and at least one arm extending from the base. The counterweight is coupled to the at least one arm. The counterweight is configured to be at least one of (i) pivotally repositionable, (ii) extensionally repositionable, and (iii) translationally repositionable relative to the vehicle.

Abstract: A modular counterweight system includes a housing, a bracket, and an actuator. The housing is configured to selectively interface with a plurality of counterweights, facilitating incremental adjustment of an overall weight of the modular counterweight system. The bracket is configured to couple the housing to the vehicle, and the housing is at least one of (i) pivotally coupled to the bracket, (ii) extensionally coupled to the bracket, and (iii) translationally coupled to the bracket. The actuator is positioned to selectively reconfigure at least one of the housing and the bracket and thereby change the center of gravity of the modular counterweight system.

Abstract: A vehicle includes a chassis and an underlift supported by the chassis. The underlift has a boom and a vehicle engaging device coupled to the boom. The vehicle also includes an operator control coupled to the underlift that allows the operator to command the boom to lift and tilt to various positions and a control system that restricts movement of the boom when the boom reaches a predetermined position as the boom is being lowered to a loading position. The control system allows the operator to move the boom after the predetermined position is reached such that the boom may continue movement in a downward direction.

Abstract: A vehicle includes a chassis and an underlift supported by the chassis. The underlift includes a boom including a vehicle engaging device coupled to the boom and a movement actuator for moving the boom. The underlift further includes a control system configured to restrict actuation of the movement actuator when the boom moves to a predetermined position; and an operator control coupled to the control system that allows the operator to control the movement actuator after actuation of the movement actuator has been restricted.
