A system for monitoring a trailer hitch assembly includes a first sensor sensing the position of a kingpin of a trailer relative to a throat of a hitch plate, a second sensor sensing a position of the locking mechanism movable between locked and unlocked positions, a control circuit coupled with the first sensor and determining whether the first sensor indicates a proper location of the kingpin relative to the throat and whether the second sensor indicates that the locking mechanism is in the locked position, and a light source proximate the throat of the kingpin and activated when the control circuit determines that the kingpin is properly located and that the locking mechanism is in the locked position, such that the light source illuminates the throat and the kingpin assisting visual inspection of the position of the kingpin relative to the throat.

Fifth wheel coupling detection system with inspection and indication lighting arrangement

A kingpin assembly comprises a housing having a recess located therein, a kingpin having at least a portion located within the recess of the housing, a collar member operably coupled to the kingpin, and a collet member extending about the kingpin and frictionally engaging the housing and the kingpin.

Fifth wheel hitch kingpin assembly

A fifth wheel slider assembly includes a hitch plate with a throat for receiving a king pin of a trailer, and a slider assembly that includes at least one rack member having a first side and a second side and supportable above a vehicle frame. The slider assembly further includes a first portion including a guide plate slidably abutting the second side of the at least one rack member, and an engagement assembly releasably engaging the at least one rack member at incremental points along a length of the at least one rack member, thereby selectively positioning the hitch plate with respect to the at least one rack member, and a second portion including at least one support bracket pivotably supporting the hitch plate, slidably abutting the first side of the at least one rack member, and readily releasably coupled to the first portion of the slider assembly.
