German crane and material handling manufacturer Sennebogen has launched the 655 HD duty cycle crawler crane. The 55 tonne capacity crane is designed for heavy-duty tasks including dragline bucket or in foundation construction.
Features include twin 16 tonne winches driven by high-pressure, variable hydraulic motors and a continuously-variable free fall brake. The wide range of optional equipment means it is suitable for various different applications. It can also use a jib, with lift heights of up to 56 metres. The unit is compact at just 3.30 metres wide.
The 655 HD is the first machine in Sennebogen's crane line to feature Green Efficiency technology. Features include temperature-controlled fan drives, an automatic start-stop system and exhaust gas treatment, all of which boost performance but minimise fuel consumption and emissions. Power is supplied by a 261 kW Caterpillar diesel engine and a multi-circuit hydraulic system.
