HYDRAULIC CYLINDERS FOR WASTE COMPACTORS

Helesul hydraulic cylinders are widely used in urban and industrial waste compaction systems. In rear-load compactors, they drive the compaction plate and loading gate, ensuring efficient compaction up to 5:1 in domestic and commercial waste, maximizing volume transported per
trip. In side-loading systems, they control the articulated arm and discharge mechanism, allowing automated operation with up to 50% labor cost reduction. In transfer stations, they move high-tonnage presses for pre-compaction, optimizing logistics and reducing transfer costs.
Eject systems use these cylinders for discharge of compacted waste under extreme pressures, while roll-on/roll-off systems employ them in tilting and locking containers of 10 to 40 tons. This
application versatility proves the robustness and reliability of the Helesul design in any compaction environment.

Helesul cylinders operate on the principle of volumetric displacement, converting hydraulic energy into controlled linear movement. Pressurized fluid (ISO VG 46 or 68 recommended)
enters the rear chamber, pushing the piston and extending the chromium-plated rod with progressive force up to 350 kN, depending on the selected model. The integrated end-of-stroke
cushioning reduces mechanical shocks, minimizing operational noise and increasing operator comfort, while extending the durability of the compacto structural components. Construction in SAE 1045 steel alloy with dual-lip polyurethane NBR/Viton seals protects against contaminants, debris, and corrosive liquids, preventing premature leakage and maintaining
hydraulic system integrity. The chromium-plated rod with hardened surface treatment resists abrasion from solid and corrosive waste, maintaining perfect sealing and extending
maintenance intervals. Operation in rapid and repetitive cycles ensures high productivity, allowing more daily trips and better fleet utilization. Versatile mounting options (clevis, flange,
trunnion) facilitate integration into different compactor models, allowing quick replacement and adaptation to customized projects without requiring complex structural modifications.
