Locking pin locating device

A semi-truck trailer-locking pin locating device comprising

• an elongated body having a first end, a second end, a first side, and a second side;
• a crossbar located proximal said first end of said elongated body, said crossbar extending through and slidably supported by elongated body, said crossbar positioned perpendicular to said elongated body and includes a roller wheel located at each end of said crossbar;
• a securing member located proximal said second end of said elongated body for securing said second end of said body to a side of a trailer;
• a spring-loaded trip flag located on said second side proximal said second end of said elongated body, said spring-loaded trip flag including a rod having an indicator flag located at a first end and a coil spring located at an opposing end of said rod, said indicator flag extending beyond said second end of said elongated body;
• a trip flag holder located on said second side of said elongated body for supporting said supporting spring-loaded trip flag in a loaded condition;
• and
• a trigger mechanism located on said second side of said elongated body, said trigger mechanism displacing said spring-loaded trip flag in a loaded condition from said trip flag holder when triggered.

A method of positioning a semi-truck trailer over a tandems axle to achieve desired weight distribution comprising the steps of:

• aligning a locking pin locating device with a targeted pinhole on a side rail of said semi-truck trailer;
• securing said locking pin locating device to said semi-truck trailer;
• setting a spring loaded trip flag of said locking pin locating device to a loaded condition;
• moving said semi-truck trailer over said tandems axle until said spring loaded trip flag is displaced from said loaded condition;
• and
• extending the locking pins of said semi-truck trailer into said pinholes of said side rail to lock said tandem axle to said semi-truck trailer.
