McCann Redi-Mix purchases two Liebherr duty cycle cranes

Liebherr crane

A pair of new HS 8100 HD Liebherr duty cycle cranes have found a home in Dorchester, Ont.

With a focus on high production, McCann Redi-Mix selected the HS 8100 HD in dragline configuration specifically for that purpose.

With increased winch size and fuel-efficient engine, the HS 8100 HD is the right addition for the McCann fleet of four Liebherr dragline machines. 

To move the machines between the gravel pits, the HS 8100 HD is engineered for easy dismantling and reassembly, using the self-assembly system. The system makes mobilizations extremely efficient, according to Liebherr. As well, hand railings on the superstructure and boom walkways increase the jobsite safety and can be transported mounted on the machine.

Larger line-pull winches

The new HS 8100 HD is the successor of the well-known HS 855 HD duty cycle crane. The dragline crane is a 100 tonne class heavy duty cycle machine. The new crane encompasses the same benefits of the HS 855 HD, but is now equipped with larger 27.5 tonne line-pull winches and a more fuel efficient 390 kW Tier 4F Liebherr diesel engine.

High flexibility and performance determine the application possibilities of the Liebherr heavy-duty cycle cranes. Whether used with a dragline bucket, slurry wall grab or casing oscillator, Liebherr claims the large-dimension diesel engines guarantees maximum performance. 

Equipment such as oscillators and vibrators can be operated without additional power pack. Moreover, the powerful and low maintenance free-fall winches are designed to fulfill high demands and afford efficient and safe operation.

Heavy duty design

The Liebherr HS series duty cycle cranes are specially designed cranes for heavy-duty cycle applications, through a high weight steel structure, to withstand the dynamic loadings and guarantee a long life. All components on the machine have a long-life span and high production performance, the company claims.
