The present invention relates to a safety lever system in a cab of an excavator, which is capable of preventing an unintended descending of a control box without the operation of the safety lever, and promoting a safer tilting of the control box through a limit means that controls the power application/short-circuit. According to the present invention, if the operator tilts the control box to get in or get out of the cab, the safety lever system shunts (i.e., short-circuit) the power of the cont...

A hitch assembly that includes an anti-rotation mechanism. The hitch assembly generally includes a hitch ball, a ball mount, and a fastener. The invention is directed to a mechanism for preventing rotation of either the hitch ball or the fastener relative to the ball mount. The anti-rotation mechanism of the present invention provides an engagement means for interlocking sections of the hitch ball or fastener with the ball mount, thereby blocking rotation of the hitch ball or fastener relative t...

A trailer hitch guide for ball-and-socket type hitches has an upright rod visible through the rear window of a towing vehicle, a base adapted to be magnetically attached to a socket-forward portion of the trailer-side hitch socket, and a lever arm that extends below the hitch socket to be tripped by the ball portion of the hitch as the towing vehicle is backed up toward the trailer. The socket-forward mounting of the base places the lever arm forward of the trailer socket, such that the guide ro...

The projection has a passageway with a pin. A locking assembly has a fixed portion. The fixed portion has a sleeve. The sleeve is secured with respect to the coupling plate. A passageway extends through the coupling plate. A removable portion has a retaining bar. The removable portion has a portion ada...

In the case of a method for hitching a trailer (2) to a motor vehicle (1), in particular a semitrailer to a semitrailer towing machine, an image sensor (5) is provided which is arranged in a hitching region (6) in such a manner that image data of the hitching region (6) are recorded. During the approach of the motor vehicle (1) to the trailer (2), stored model data of the hitching region (6) of the trailer (2) are segmented in the image data recorded by the image sensor (5) and are in each case ...

A towing apparatus mounted to a frame of a vehicle includes a receiver and an energy management device. The receiver is operably connected to the energy management device and the energy management device is operably connected to the vehicle frame. When the receiver is moved in a first tow direction, the energy management device is isolated and the tow force is coupled directly to the frame. However, when the energy management device is moved in a second, generally opposite direction, the energy ...

The invention relates to a flexible floor for an intercommunication bellows between two cars which, while they are traveling in a straight line, move in a longitudinal direction, said floor presenting transverse undulations enabling it to follow the relative displacements of said cars as they are going around bends, while also enabling passengers to go between the cars by walking on the top face of the floor, said transverse undulations being reinforced by metal blades extending in a transverse ...

A device for selectively compressing and decompressing an anti-sway bar. The device replaces the hand crank on traditional anti-sway bars and relieves drivers of having to get our to their vehicles to compress or decompress the anti-sway bar by hand. A lever is used to compress the anti-sway bar. The lever's head is attached to the anti-sway bar at the same position as the old hand crank, using the bolts and nuts from the hand crank. The lever is raised with the assistance of an electric motor t...

A trailer stability control apparatus for a vehicle and a trailer includes a trailer hitch assembly interconnecting a rear end of the vehicle and a front end of the trailer. The trailer stability control apparatus also includes at least one controllable damper connected to the trailer hitch assembly. The trailer stability control apparatus further includes a controller electrically connected to the at least one controllable damper for providing continuously controllable damping forces between th...
