With a main boom length of 6 – 20 m, this robust machine is ideal for pipework applications (well construction or geo thermal applications) to a pipe diameter of 60 – 120 cm. Construction sites of this kind are often of limited duration and difficult to reach. Quick operational readiness and easy transportation between construction sites are therefore the major advantages of the SENNEBOGEN 620 HD. Even in heavy-duty drag line operation, the 620 HD impresses with the robust design of all its components and the telescopic crawler undercarriage which can be extended to around 4 m external width. The 600 mm flat shoes guarantee the best possible stability of the machine. 臂根有油缸机构可以折叠12米主臂,快速安装,副臂可以折叠,整体高度还只有3.13米高
