Liebherr shows off lineup of demolition equipment

For the second year in a row, Liebherr USA Co. was the lead sponsor of the NDA Live Demolition event. The company featured five machines at Demolition Rockies: the R 950 High-Reach Demolition Excavator; the R 946, the R 936 and R 926 crawler excavators; and the A 924 Excavator.

Liebherr high-reach excavators, such as the R 950, are purpose-built for selective deconstruction of large industrial buildings. The entire machine, including the demolition front, is designed and manufactured by Liebherr. At the Live Demolition, the R 950 was equipped with an Epiroc CC 3100 U Combi-Cutter attachment.

High-reach machines “have eliminated the wrecking ball,” according to Travis Willison, vice president of the demolition division of Toronto-based GFL Infrastructure Group. Willison’s company purchased the R 950 featured at the event, and he was on-site to see it in action.

“The wrecking ball was a great invention for its time,” Willison says, but modern demolition machines “are much safer, much neater, much quicker.”

In addition to the R 950—which offers a reach of 83 feet, making it one of the tallest and largest machines featured at the event—participants also had an opportunity to operate the R 946 equipped with an Epiroc SC 6200 hydraulic shear. The R 936 was equipped with an Epiroc BP 2050R bulk pulverizer attachment, which got plenty of test runs working to reduce a mound of concrete to rubble.

The full line of earthmoving, material handling and demolition equipment from the Liebherr USA Co. Construction Equipment division is designed with built-in versatility that meets the unique demands of the demolition industry.
