The first Liebherr’s LRT 1100-2.1 rough terrain crane with counterweight upgrade in the United States was brought to Liebherr Mining Equipment Newport News site to assemble a T 264 Liebherr mining truck.

The LRT 1100-2.1 rough terrain crane was upgraded in 2022. The upgraded steel counterweight is increased by 1 metric ton resulting in an increased lifting capacity, allowing the LRT to hoist loads beyond what’s capable for the rest of its class.

The counterweight is also more compact providing a better rear view in the cab, minimizing blind spots. This upgrade also allows for increased load charts as well as inclination charts, aiding in operation up to 2 degrees from level.

The upgraded LRT was taken to Virginia to assist in assembly of an on-site mining truck. The rough terrain crane allowed for a smooth and rapid assembly of the T 264 mining truck and fulfilled any lifts needed at the site, the company said.

With no down time, the LRT crane also allowed the job to be finished four days ahead of schedule, saving both time and money.

“It can be very hard to schedule cranes for builds like this,“ noted Thomas Coenen, mining equipment product support representative, Liebherr. “Auxiliary cranes are often shared and used for maintenance of heavy mining equipment and other lifting needs around mining sites. In this instance, I was able to use the upgraded LRT from Prillaman’s crane rental. Using one crane that can lift the truck makes the project easier, and we can complete the build faster. This also meant no downtime or crane changes for different components to be lifted.“
