Caterpillar continues to position the 336 - the anchor of its next-generation large excavator range - as a roughly 36,800 kg operating-weight crawler excavator powered by the Cat C9.3B engine delivering 234 kW (314 hp) at ISO 14396, paired with maximum digging depth of 7,510 mm and swing torque of 144 kN·m. The 336 is designed for large-scale earthmoving, quarry production, heavy infrastructure, and mining support applications where production-per-liter-of-fuel and operator accuracy directly determine project profitability.
The machine's defining engineering feature is the "Cat Grade 3D Ready" configuration - all hardware required for the 3D grade-control system is installed and tested from the factory, providing a clean upgrade path for contractors who need high-accuracy grading without aftermarket retrofitting. The 336's standard "Grade with 2D" system provides guidance for depth, slope, and horizontal distance to grade through the standard touchscreen monitor, delivering up to 45 percent improvement in operating efficiency over traditional grading operations. Combined with "Grade Assist," which automates boom, stick, and bucket movements so the operator can stay on grade with single-lever digging, the 336 reduces operator fatigue while maintaining production accuracy through extended shifts.
The 336's "E-fence" function prevents the excavator from moving outside operator-defined set points - a critical safety feature when working beneath structures, near traffic, or within confined urban job sites where the boom or upper structure could strike adjacent obstacles. "Cat Payload" provides on-the-go weighing for real-time payload estimates without swinging, preventing truck over-loading or under-loading and enabling fleet managers to hit loading targets precisely. When paired with VisionLink Productivity, the Cat Connect telematics platform allows remote jobsite analysis and individual-asset production tracking. Combined with baffle-plate reinforcement in high-stress boom areas for improved strength-to-weight ratio, and Cat's established global dealer and parts network, the 336 positions itself as the production leader against the Komatsu PC360, Volvo EC300E, and Hitachi ZX350 in the global large excavator segment.
