Product Description:
When transforming your excavator into a high-capacity material handling powerhouse, equipment synergy is everything. Our 3.5 CBM Hydraulic Rotating Excavator Clamshell Grab is meticulously engineered to bridge the sweet spot for 20–40 ton excavators. Rather than merely hanging an attachment, this grab is calibrated to harmonize with your carrier machine’s hydraulic output. Operating seamlessly within a 180–200 bar working pressure and an optimal 65–80 lpm working flow, it ensures your excavator’s hydraulic pump works at peak efficiency without system strain, translating engine power directly into relentless digging and biting force.
Engineered for Extreme Loads and Heavy-Duty Agility
Weighing in at a solid 3000 kg, this 3.5 m³ grab strikes the ideal structural balance for mid-to-heavy excavators—heavy enough to leverage natural gravity for deep penetration into packed materials, yet structurally balanced to prevent undue front-end wear on your boom and arm. At its heart are heavy-duty hydraulic cylinders featuring a robust 140 mm bore and an 80 mm rod diameter, designed to resist high-stress fatigue during continuous multi-layer digging. Combined with 360-degree hydraulic rotation, it allows operators to execute complex, multi-angle material placement with pinpoint accuracy, drastically cutting down repositioning time and reducing operator fatigue.
Target Materials & Jobsite Versatility
Designed for maximum productivity across high-volume material handling, this clamshell grab excels when paired with your fleet's heavy excavators:
