An apparatus for measuring distance when moving a vehicle, for instance, for measuring how far to move a tractor of a tractor-trailer rig when sliding (e.g., tandem) axles of the trailer, for example, to equalize weight between wheels or axles of the rig. A scale is mounted on the vehicle with (e.g., evenly-spaced) indicia arranged in a line parallel to a forward or reverse direction of the vehicle. The scale is positioned on the vehicle where the driver, while driving the vehicle, can see the scale and can sight past the scale to a stationary visual reference located outside the vehicle (e.g., on the driving surface) to see how far the vehicle has moved. The scale may be on an elongated member which may be attached to the vehicle, for example, to a step below the driver.

A trailer tandem slide stopping device for facilitating positioning of a trailer tandem includes a guide pin, which insertable into a first hole of a plurality of holes positioned in an outer rail attached to a the trailer. The first hole is positioned past either a rearward or forward end of an inner rail of the tandem trailer. The guide pin abuts the rearward or forward end of the inner rail upon driving a semitruck hitched to the trailer in forward or reverse, respectively, to move the trailer tandem toward the rear or front of the trailer, respectively, at which point a locking pin of the trailer tandem is aligned with and positioned for insertion into a target hole of the plurality of holes. The target hole corresponds to a desired position of the trailer tandem relative to the trailer.

A moveable subframe system, a slider box improvement system, and methods of use are presented. The present disclosure provides the state of the art with a safer, easier to use slider box system. The present disclosure relates generally to a moveable subframe system, a slider box improvement system, and methods of use. The disclosure is a device which relates generally to subframes for heavy-duty vehicles, such as tractor trailers. The disclosure is directed to a moveable subframe for tractor-trailers which makes moving the tandem wheelsets forward and backwards easier and more efficient, especially in heavy loaded circumstances. More specifically, and without limitation, the present disclosure may be used to move and/or shift heavy applications. The disclosure provides a slider box system that enables an operator to easily move and/or adjust the location of the trailer and/or trailer load relative to the axle and/or axles.

An adjustable trailer hitch and king pin assembly that may be moved longitudinally to adjust the position and weight distribution of a trailer relative to a truck. The disclosed assembly may allow a trailer to be utilized with various different sized and configured trucks while maximizing the cargo carrying capability and efficiency thereof. In one example, an adjustable trailer hitch is provided having a slidable king pin assembly that may be adjusted forwards or backwards to move the king pin to the desired location relative to the truck and trailer. In another example, a removable king pin may be provided that may be removed and moved to a different location according to the weight and desired weight distribution of a truck and trailer combination.

An articulated lorry that includes a tractor which has a fifth-wheel coupling and a trailer which has a connecting element which is reversibly detachably connected at a connection point to the fifth-wheel coupling. A tensioning device relieves a load on a wheel axle of the trailer, loads a drive axle of the trailer, and applies a force that counteracts a relative pivoting movement between the tractor and the trailer around a pivot axis which is oriented parallel to a transverse vehicle direction of the tractor and/or of the trailer. The tensioning device tensions the tractor to the trailer.

In a caravan that includes a battery and an axle, the battery is designed to supply power to a traction drive of a tractor vehicle and/or to an optional drive unit of the caravan when same is towed on the road, and the battery is mounted so as to be movable in the longitudinal direction of the caravan and can be moved by an adjustment mechanism.

A container transport system for transporting an intermodal freight container includes: a tow assembly pivotally coupled to a tow vehicle, the tow assembly including a support frame, a boom assembly mounted on the support frame, the boom assembly having a boom frame and a lifting actuator mounted on the boom frame; a lift beam shaped to attach to an end of the intermodal freight container, the lift beam mechanically associated with the lifting actuator; a dolly removably coupled to one of the tow assembly and tow vehicle, the dolly including a bogey frame including a plurality of wheels attached to the bogey frame, a pair of brackets located on sides of the bogey frame, the brackets spaced apart such that a width of the intermodal freight container fits between the paid of brackets.

A weight sensing assembly for a semi-trailer truck enabling balancing of a load includes a sensing module, which is one of a plurality thereof. The sensing modules are mountable to wheels of the semi-trailer truck so that each axle has a sensing module engaged to outside wheels thereof. The sensing module obtains a pressure measurement of a tire engaged to the wheel and transmits it to an electronic device. Programming code on the electronic device enables it to utilize a pressure changes, upon positioning of a load upon the semi-trailer truck, to determine a weight that is positioned upon an associated axle. The electronic device calculates adjustments to positions of a sliding fifth wheel and of sliding tandems of the semi-trailer truck to obtain positions thereof that will achieve a legal weight distribution of the load. The electronic device presents, upon a screen thereof, the adjustments to a user.
