For more than 20 years, SENNEBOGEN telescopic cranes have embodied the optimum combination of flexibility, cost-effectiveness and quality. The new SENNEBOGEN 673 R-HD rounds out the broad product spectrum as the first telescopic crawler crane of the new E-series.
The 673 R-HD was designed for high performance. Thanks to its telescopic boom, the crane can handle any demanding job on the construction site. In comparison to other crane designs, the SENNEBOGEN telescopic crawler crane offers a host of advantages.
Easy to transport – fast setup and high flexibility
Less than 3 m wide on the highway, the machine can be transported quickly and easily. The train can be comfortably hauled on a long-distance flatbed truck. The machine is ready to use as soon as it arrives at the construction site. With the telescoping crawler tracks, time-consuming leveling and supports, as they are necessary with AT-cranes are a thing of the past. The machine can easily work on a slope up to 4 degrees. The 673 R-HD easily gets the job done on the construction site with its 36 m long boom arm. Two fly boom versions of 8 and 15 meters extend the maximum reach to 51 meters. The integrated heavy-duty jaw functions at an offset angle up to 40°. The machine can reliably carry loads up to 70 tons. The four-stage telescoping boom extends smoothly under hydraulic actuation; all the functions are fully available even under loads which maximizes flexibility – a complicated single cylinder system can be omitted.
As thy first telescoping crane of the new E-series, the 673 R-HD satisfies tier 3b/4 emission standards thanks to the powerful 160 kW Deutz engine in combination with a soot particle filter and cutting-edge exhaust aftertreatment system. In addition, the machine offers significant energy savings in Eco Mode operating at a reduced engine speed. The new SENNEBOGEN SENCON control and diagnostics system offers a clear view of all operating parameters and easy, intuitive user control, as well as the ability to fine-tune machine performance and quickly process error messages. In addition, the load torque limiting system can be easily as reliably monitored.
Maximum driver comfort and a range of uses
The telescoping crawler tracks of the SENNEBOGEN 673 R-HD enables safe and flexible work. Thanks to a large four-point support base and wide baseplates, the machine can stand securely even in dynamic tasks on difficult terrain. The compact dimensions come in handy, particularly in narrow working spaces. In addition to its use as a crane, the 673 R-HD can also operate on a working platform rated to bear up to 1000 kg. This significantly expands the working range of the machine and enables a host of additional uses.
For the driver, the SENNEBOGEN Maxcab ergonomic cabin maximizes working comfort and ease of use. The comfortable joystick control, large sliding door, optional peripheral cameras and stable grating next to the cabin are all ergonomic features that simultaneously enhance safety. To provide an excellent view of the work area, the SENNEBOGEN 673 R-HD can optionally come equipped with an hydraulically elevated cabin. The cabin can be raised an additional 2.7 m and tilt up to 30 degrees to provide a commanding view – a unique solution in construction industry.
In addition, the SENNEBOGEN 673 R is very easy to service. The central lubrication point for all articulations and the slewing ring reduces the required amount of servicing, optimizes accessibility to servicing points and important components, and saves time during operation.
