Sennebogen has announced the launch of a new duty cycle crane that is aimed at demanding applications such as diaphragm wall construction.
According to the manufacturer, the 70t 670 HD crane has a powerful multi-circuit hydraulic system, and the strong slewing drive that make it particularly well-suited to special underground engineering.
The crane is equipped with clamshell grab or drag-line bucket and two 16t freefall winches, with the option to upgrade to 20t. The new model offers maximum boom lengths of up to 56.9m and an auxiliary jib and fly boom as options, which means it can be used as a conventional crane.
The new duty cycle crane has been designed for operation on sites with restricted working space with compact dimensions and an an easy ballast mounting system save time and money when transporting between construction sites. The crawler chassis can telescope down to a width of just 3m.
