Before installing the rail joint bar, the power supply of the electrical appliance and circuit under test should be blocked, and the relevant components should be temporarily grounded. Install two bolts on each joint of railway fishplate, that is, one for each steel rail head. When installing railway fishtail bolts, the flat spring washers should be installed first, and the opening should be downward. The contact part of the rail fishplate and steel rail and fishplates bolts should be oiled.
In addition, when purchasing and installing a rail joint bar, pay special attention to the type of rail fishplate and whether the specifications are appropriate. The rail fish plate, as a connecting fastener for the connection between the rail and the rail, is a useful product for rail connection. The connection of railway fishplates saves time and labor than steel rail welding, and the rail fishplates can be replaced at any time.
