Bridge Beams Set Over a Live Railroad
Four bridge beams set over active rail with the LTM 1400-7.1 — precision work inside a train schedule.
The lift
Northwest used the Liebherr LTM 1400-7.1 to set four bridge beams over live railroad tracks near Vian, Oklahoma. Working over active rail means every pick is planned to the minute and cleared with the railroad — there are no do-overs inside a traffic window.
| Spec | Value |
|---|---|
| Load | 4 bridge beams |
| Crane | Liebherr LTM 1400-7.1 |
| Constraint | Live railroad traffic below the picks |
| Industry | Civil construction |
Railroad and bridge work is recurring business for Northwest — from beam sets to rerailing derailed cars and picking locomotives.
