This exciting new wheeled harvester generated much attention with a host of new innovations.The unique crane structure and sleek design give the Scorpion an original and modern look. Logging-on examines some of the interesting features:
- Levelling of the cabin and crane. The axis point of lateral levelling is very low due to a triple-frame structure. This keeps the cab and crane level and reduces sideways movement. Stability is also improved as the balance point of the crane and cabin is on the machines centre line.
- Excellent visibility in all directions. The fully symmetrical crane and cab on a single slewing ring allows very good visibility to the harvester head, even in dense stands. The C50 double arm lifting boom reaches over the operator to provide good visibility in all directions. The cab has large windows with narrow pillars, and also has a roof window.
- Machine stability. An intelligent stabilisation system is used which follows the position and load of the crane. Stabilising cylinders press the rear wheels and frame down towards the crane direction. This gives support to the Scorpion when working to the side. The stabilisation systems also operates while the machine is moving, allowing the operator to continue working. A safety feature prevents the machine from moving should stability become problematic.
- Crane control. The C50 crane has been built with a similar hydraulic parallel function as the C22 and C44 models. Other advantages have already been mentioned above. The parallel function is made possible with a multi-chamber cylinder which pumps oil to the lifting cylinders according to the extension boom movement direction. Depending on the configuration, crane reach is either 10 or 11 m (33 or 36 ft). It has a lifting force of 252 kNm and a slewing force of 57 kNm. The slewing angle is 280 degrees.
- Ergonomics. Machine stability, the excellent vision, the smooth operation and the ergonomically superior cab all contribute to a good operator experience.
The Scorpion is powered by a 6-cylinder 210 kW (286 hp) engine that meets emission requirements through the use of cooled exhaust gas recirculation (EGR) and selective catalytic reduction (SCR). Serial production of the Scorpion will start at the beginning of 2014. Source: www.ponsse.com
