    • How the product works and how it is used.

A bridge is a structure built to pass over obstacles such as a river, valley or road. A lifting bridge is a movable bridge. The bridge deck is hinged on one end that moves to allow passage for boats. For small bridges, bridge movement is operated by the user.

Generally, the bridges are powered by electric motors so we have installed an electric motor with forward and reverse remote control.

    • Short description of the parts.

Lifting Bridge has a tower, it has a bridge deck, it has a hinge, it has two braces, it has two pulleys and one axle and it has a handle. We have installed an electric motor with forward and reverse remote control.
