This 2023 Sennebogen 855R-HD with K21 boom configuration and Green Hybrid energy recovery is a Certified Pre-Owned Sennebogen — backed by a 12-Month / Remainder of 2,000-hours Hydraulic and Structural and warranty — and at just 800 operating hours, it is essentially new. This E-Series crawler machine will be available in June and is accepting inquiries and deposits now.

The K21 configuration delivers 68.8′ of total reach via a 12.1m straight compact boom and 9.5m curved grab handling stick with special materials handling kinematics — purpose-built for massive scrap piles, port terminals, and mill yard environments where reach, stability, and throughput are the operating mandate.

The 855R-HD is equipped with the Sennebogen Green Hybrid energy recovery system, recovering energy during boom lowering to reduce fuel consumption by up to 30% — a significant operating cost advantage over a standard machine at this production level, and a meaningful differentiator for operations focused on efficiency and long-term cost management.

Power comes from a Cummins L9 C310 producing 314 HP at 2,100 RPM, Tier 4 Final compliant, with an automatic idle speed stop and Eco-mode for additional fuel savings during lower-intensity cycles.

The reinforced R-HD crawler undercarriage provides a wide footprint and exceptional stability on uneven or unpaved surfaces — making this machine the right choice for high-production environments where a wheeled undercarriage would compromise stability or surface performance.

The maXCab Industry E300/260 elevates hydraulically to 3.0m and extends 2.6m out, with bulletproof front and skylight glass, SENCON diagnostics, SENtrack telematics, air suspension seat with lumbar support, and automatic A/C — giving operators the visibility and comfort needed for long, high-cycle production shifts.

Available June 2026 — inquiries and deposits accepted now.
