About this file

This is a specification sheet for a bear trap trailer issued by the Michigan Department of Natural Resources (DNR). The document details the technical requirements and construction specifications for a single trailer unit designed for wildlife management purposes. The trailer specifications include overall dimensions of 12 feet in length, 51 inches in width at the frame (74 inches outside of rims), and 51 inches in height from the ground. The trailer is equipped with a 2-inch receiver hitch, 4-way flat plug, 1000-pound rated tongue jack, LED lights, and a spare tire with boat crank mount. The structure incorporates 2-inch by 6-inch, 2-inch by 3-inch, and 3-inch by 3-inch tubing components, along with various mounting plates, pulleys (2-inch by 5/8-inch), and cable systems designed to support the operational function of the bear trap mechanism.

The trailer includes specialized components for trap operation such as polyethylene wear bars approximately 12 inches in length to be affixed to each angle post at trap contact points using threaded steel inserts. The specification sheet provides detailed dimensional drawings and construction guidance for all major components. The completed trailer must be finished with a flat forest green powder coat before delivery and includes a license plate bracket with integrated license plate light mounted on the left driver's side fender. The document serves as a comprehensive technical guide for manufacturing or procurement of the trailer to ensure it meets Michigan DNR standards for bear trap transportation and operation.
