ELHO Scorpio stone picker at CIA Ltd.
At CIA Ltd, we strive to maximize land usage efficiency while sustaining soil quality without compromise.
Thousands of years ago, the tremendous power of ice age glaciers carved through the Southern Alps and released rocks and sediment from the Arthur’s Pass headwaters, forming alluvial deposits from the mountains to the sea, a common occurrence on many New Zealand farms.
Farms have been carved out of this rich soil, however, some land has yet to reach its full potential due to uncompromising stones and rocks scattered on the surface.
Stones in the field constitute a significant cost burden annually, due to their potential to disrupt harvesting machines. Damaged equipment must be repaired or replaced, with additional loss of working hours. The downtime resulting from stone-related damage to harvesters or mowers can range from one week to more than that.
To address this long-standing difficulty, CIA Ltd has included the ELHO Scorpio 550 to its range. This powerful equipment efficiently collects stones without damaging the soil.
The ELHO Scorpio 550 stone picker is equipped with unique solutions that make it easy to remove stones from fields.
One of the key features of the Scorpio 550 is fully hydraulic drive. The hydraulic flow is 85 litres/minute, which is achieved with 110-150 bar. The hydraulic drive is designed for use with a tractor’s normal dual-function hydraulic coupling and a nominal pump size of 110 l/min. The maximum continuous use is 24 kW, and the tractor’s own cooler keeps the oil temperature optimal.
Automatic depth adjustment enables the machine to follow the surface of the ground with a constant working pressure. This makes it easy and pleasant to operate the machine, even in extremely dusty conditions.
The hydraulic system can temporarily increase pressure to the second pickup motor when needed, and the lifting force at the end of the tines is 700 kg.Sturdy Hardox 500 tines can rotate at higher speeds than traditional steel spring tines. The higher rotation speed improves sieving and soil removal, and it also breaks up organic materials better. The diameter of the picker is 1.8 metres and rotates at 80 r/min, while the tines rotate at 125 r/min.
The Hardox 500 tines have rubber bushings, allowing the sieve steel bars to flex laterally. All of the tines flex backwards and lift out of the sieve to prevent blockages. The maximum tine flex is 500 mm.
