Crossing Brazos River

13 July 2018


Two Liebherr LTM 1500- 8.1s were used for the construction of the Loop 340 bridge over the Brazos River in Waco, Texas.

The all terrain cranes, with maximum capacity of 500t, were supplied by Austin Crane Service— part of Davis Crane companies—on behalf of the contractor JD Abrams.

The job involved the setting of seven spans—five bays of 105ft TX-54 beams, one 30ft and one 75ft span of TX-28 beams.

The Liebherr LTM 1500-8.1 has a variable telescopic boom system: owners can set it up with either a 50m or an 84m boom. On this job, the crane on the north side of the river was set up with an 84m long boom and Y-guy boom support system. The second one was set up on a special arrangement on the river bank with 160ft of luffing jib.

The jobsite was very challenging to get the cranes in place, Davis Crane said, but the job was completed in its two day time frame.

The eight-axle LTM 1500-8.1 was first unveiled at Bauma 1998 and became one of Liebherr’s most successful models, with the 500th unit delivered in 2016.

The manufacturer has been continuously adding technological improvements and upgrades to it to ensure it remains up to date. The machine now comes with telescopic guying and the option of fully disassembling the telescopic boom.

The “removable telescopic boom” option results in low axle loads, allowing users to obtain permits for travelling on roads more easily.

Over the years, this crane has been used in many infrastructure projects, wind farms, power plants and various other applications.
