Broken rock, sand, gravel and natural stone are quarried on the eastern edge of the Swabian Jura. So as to strip the blasted material effectively and quickly, a rock loading bucket is used,from the attachment specialist HS-Schoch with a cutting width of 3970 mm and a capacity of 6.8 m³, (Fig.) which is directly mounted on a VOLVO L350F.
The complete attachment is made of HARDOX metal wearing plate and has been equipped with a tooth system and shields from ESCO. HS-Schoch is a partner of HARDOX Wearparts certified by SSAB and they have gained decades of experience and know what is important when processing HARDOX steel. Blades and side wings are most strongly stressed during stripping. For this reason, the wear protection experts at HS-Schoch decided to make these neuralgic points as follows – the trapezoidal blade of HARDOX HiTuf of 70 mm and the wings of HARDOX 450 of 40 mm thickness. This also applies to the bucket bottom that is made of HARDOX 500 of 15 mm and is additionally equipped with wear rails.
The ULTRALOK tooth system from ESCO ensures the correct cutting. ESCO is one of the leading manufacturers of technically exacting earthmovers and resistant wear parts used for construction and mining, for dredging and recycling. Eight tooth tips, type ULTRALOK U55-AP, cut through the blasted rock during stripping. The rock loading bucket has been additionally equipped with ESCO TOPLOK shields between the teeth. The cast Toplok® shields of hardened ESCO alloys are ideal for abrasive use and, in addition to a good penetration behaviour, offer excellent protection against impact stress.
