New 90 tonne Sennebogen crawler
By Alex Dahm03 April 2009
Sennebogen in Germany is launching a 90 tonne capacity lattice boom crawler crane. Target applications for the 690 HD include special civil engineering, mining, demolition and materials handling. In addition to lifting work, the 690 HD is designed for heavy duty applications, including hydraulic diaphragm wall grabs, vibrator, drag line and grab.
To help handle heavy duty tasks there are 291 or 447 kW engine options, 880 litre hydraulic tank and large oil cooler. The 1,000 litre fuel tank reduces idle time. It has a four-circuit hydraulic system with options to suit custom configurations and attachments.
Winch options are 16, 20, or 25 tonnes and there is mechanical synchronisation. Extra winches are available on the upper structure and in the lower boom section. The line speed of 115 m/min is the highest on the market, the manufacturer says.
