McNally Marine Using Liebherr Cranes in New Brunswick Port Development Project
The project includes installing a 400-meter dock to expand the Ro-Ro capacity of the Port of Belledune, and deepening the inner and outer harbor navigation channels to 17 meters. Dredging amount was 200,000 cubic yards of soft sediment.
The company used an 895 Liebherr crane equipped with a 16-cubic-yard Cable Arm bucket, and a Liebherr 885 equipped with a 13-cubic-yard Cable Arm bucket for the dredging, loading into scows that took the material to a shore-based rehandling station. There, the material was loaded into rock trucks, then taken to in-water, sealed holding ponds. The material was unsuitable for ocean disposal.
McNally began mobilizing for the project in May 2010, bringing equipment from its facilities in New Brunswick, Québec, Nova Scotia and the Great Lakes. By the time of shutdown for cold weather, the dredging was largely completed. At the beginning of March, the area was in the middle of a six-week hiatus because of weather, awaiting warm weather to complete the caissons for the sea wall of the dock.

Liebherr Company Profile
Liebherr excavators and cranes are widely used in the dredging industry. Where extremely heavy-duty digging is required, dredges equipped with the company’s large backhoe excavators are commonly used. Liebherr’s line of hydraulic cranes are successfully used for dredging with clamshell buckets.
A family business, the company was established in 1949 by Hans Liebherr, who saw great success with his first mobile tower crane. Today, the company produces construction machinery and a diverse line of products and services for other industries. The business now comprises 100 companies on all continents and a work force of more than 32,000.
The Liebherr Group is divided into independent company units, to ensure proximity to the customer and the ability to respond to market changes. Management of the production and sales companies for each segment is in the hands of divisional control companies. The Liebherr Group’s holding company is Liebherr-International AG in Bulle, Switzerland, which is entirely owned by members of the Liebherr family.
The family business is in the hands of the second generation and is jointly managed by Isolde Liebherr and Willi Liebherr.
