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.

The trailer tongue system is provided and includes a trailer frame, an arm support assembly secured to the trailer frame, and a trailer connection arm assembly. When the trailer tongue system is ready for deployment, the hydraulic system support activates. The hydraulic system support permits the arm support assembly to pivot between first position and second position depending on whether the user would like to connect or disconnect a trailer from a power vehicle. The arm support assembly enables the trailer arm of the trailer connection arm assembly to be either raised or lowered depending on whether the user would like to connect or disconnect the trailer.

A height adjustable hitch receiver is disclosed and described.

An axle load monitoring system for a load-transporting motor vehicle having one or more auxiliary axles wherein the monitoring system detects a noncompliant carrying-weight condition when the current gross vehicle weight is more than a prescribed maximum allowable gross vehicle weight assigned thereto and/or the current carrying weight of any primary axle and any designated axle group is more than a prescribed maximum allowable carrying weight assigned thereto. And if the current gross vehicle weight is equal to or less than the prescribed maximum allowable gross vehicle weight and the current center of gravity of the vehicle is in a compliance-manageable range which is established by the monitoring system and specific to the vehicle, the monitoring system recommends auxiliary axle usage that would result in compliance with the prescribed maximum and minimum allowable carrying weight assigned to each of the primary axles, any designated axle group and any utilized auxiliary axle.

A container transport system and method of operation can include: providing a vehicle having a subframe assembly coupled thereto, the subframe assembly including a lifting arm and a clamping arm; clamping the clamping arm onto a corner fitting of a cargo container; raising the lifting arm for raising a portion of the cargo container; inserting a jack stand below the cargo container; lowering the lifting arm for tilting the cargo container on the jack stand, the jack stand configured as a fulcrum; positioning a container trailer below the cargo container; and raising the lifting arm for pivoting the cargo container on the jack stand and lowering the cargo container onto the container trailer.

Various implementations include a handle attachment device. The device includes a body and a drive shaft. The body has a first portion and a second portion. Each of the first portion and second portion defines at least one fastener opening. Each of the at least one fastener opening defined by the first portion is alignable with one of the at least one fastener opening defined by the second portion. The first portion and the second portion are clampable on a crank when the device is in a mounted position. The crank has a crank rotational axis.

A shock-absorbing tongue assembly for coupling a rotary cutter with a work vehicle includes a coupler configured to couple to the work vehicle, and a linkage mechanism having a proximal end at the rotary cutter and a distal end at the coupler. The linkage mechanism includes a suspension element configured to dampen energy transferred between the rotary cutter and the work vehicle, a primary linkage mechanism extending from the rotary cutter, and a secondary linkage mechanism extending between the primary linkage mechanism and the coupler. The secondary linkage mechanism is configured to rotate about the primary linkage mechanism while maintaining the coupler in a level condition.

A height adjustable hitch receiver is disclosed and described.

Presented is an automatic trailer hitch for enabling removable coupling between a towing vehicle and a towed vehicle. The automatic trailer hitch includes a base module, a vertical climbing module, linchpin modules configured for selectively driving the linchpins in an engaged position and a disengaged position, and a rotation module. The vertical climbing module is configured to vertically displace a hitch along a single axis. The plurality of linchpin modules is configured for selectively driving the linchpins in an engaged position and a disengaged position. A controller module is operatively coupled to each of the vertical climbing module, the linchpin modules, and the rotation module to monitor and control the multiple-axis position adjustment of the hitch(s) of the automatic trailer hitch.

An automated system is provided for aligning a vehicle tow ball with a tow cup of a trailer. The vehicle has a controller connected to at least some of the vehicle steering, transmission and braking systems to enable the controller automatically to steer and/or move and/or brake the vehicle. Sensors at the rear of the vehicle detect the presence of an object within a region behind the vehicle. The sensors are connected to the controller to utilize the data from the sensors to identify the tow cup of a trailer located within the region behind the vehicle, and to control the reversing of the vehicle in order to bring the tow ball into alignment beneath the identified tow cup so as to facilitate coupling of the tow cup onto the tow ball.
