An improved coupler for a tongue on a towed vehicle that attaches to a tow hook mounted on a towing vehicle to either pull the towed vehicle over a road or to pull the towed vehicle located on an elevated surface. The coupler includes an elongated tongue tube attached to the end of the tongue attached to the towed vehicle. Upper and lower rings are axially aligned and mounted or attached to the front surface of the tongue tube. The rings are spaced apart on the tongue tube to allow the towing vehicle to pull or push the towed vehicle over the same roadway or an elevated surface. Brackets are used between the tongue tube and the trailer tongue to prevent compression, collapse, and fore to aft or aft to fore movements. An adjustable jack is attached to the side of the tongue tube. An optional lid is provided over the top opening of the tongue tube that covers a storage compartment inside the tongue tube. An optional chock holder plate and a pair of compatible chocks may be placed inside the storage compartment.

The various embodiments disclosed herein relate to an interchangeable hitch mechanism that is coupleable to a pusher device. Other implementations relate to a pusher device having such an interchangeable hitch mechanism that can be removably coupleable to a manual jack pallet.

A combined hitch and anti-roll system that includes the support structure, hitch system, and anti-roll system and may be removably mounted to a vehicle is also disclosed.

An adjustable hitch mounted on a self-driving machine and providing a coupling to a trolley. The hitch includes generally two gas struts connected to two parallel arms to bias the hitch in an upward direction pivoting with respect to the driving machine. This enables the hitch to be moved in a vertical direction to facilitate it connecting with the trolley, typically the frame of the trolley, to allow for the hitch to be lowered to engage a frame of the trolley. An engagement assembly, being connected to the lifting arm, wherein it has a face and a jaw that are configured to securely engage with the wheeled equipment.

A system for automated trailer weight distribution, including: A system for automated trailer weight distribution, having a tow vehicle with a hitch mount having a spring bar. The system may also include a trailer and a spring bar mount disposed on the trailer and having an initial position relative to the trailer, where the spring bar mount is configured to receive and engage the spring bar. Furthermore, a weight distribution measurement device disposed in association with the tow vehicle and being configured and arranged to determine a weight distribution of the tow vehicle when the spring bar is engaged with the spring bar mount and a weight distribution actuator can be configured and arranged to adjust the height of the spring bar mount while engaged with the spring bar, wherein the weight distribution actuator communicates with the weight distribution measurement device such that said weight distribution measurement device operates to activate the weight distribution actuator to adjust the position of the spring bar mount.

A system for powered trailer weight distribution having a hitch mount with a spring bar, and a trailer with a spring bar mount disposed on the trailer and having an initial position relative to the trailer, wherein the spring bar mount is configured to receive and engage the spring bar, and a weight distribution actuator configured and arranged to adjust a position of the spring bar mount relative to the spring bar while engaged with the spring bar, wherein the weight distribution actuator is connected to a power source that provides power to the weight distribution actuator, facilitating the adjustment of the position of the spring bar mount.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar having a modulus of elasticity, the moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a releasable tension member comprising a top portion configured to be pivotally supported by a frame member of the trailer and configured to pivot about a horizontal axis, and a bottom portion configured to support the rearward end of the moment bar; and a moment bar preload mechanism configured to push up the moment bar rearward end to thereby preload the moment bar; wherein, when the moment bar rearward end has been preloaded, the releasable tension member can be pivoted between a first angular position and a second angular position below the preloaded moment bar; wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar, a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar, and wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle; and wherein the length of the moment bar is less than 28 inches is disclosed.
