High-Performance Hydraulic Cylinder for Livestock Feed Unloaders

The Helesul Hydraulic Cylinder for Feed Unloaders performs with precision on vertical trench-type silage unloaders, controlling the elevation and descent of the cutting or scraping assembly. This enables fine adjustment of cutting depth and uniform silage extraction — regardless of compaction level — thanks to its robust structure and high-performance seals that maintain integrity even in the presence of dust and plant particles.

On round and square bale unloaders, the Helesul cylinder actuates the opening and closing of claws, arms, and containment doors safely and quickly. In TMR wagons and feed distributors, it drives the precise movement of gates and lateral discharge systems, ensuring homogeneous diet distribution at the feed bunk and reducing feed waste — delivering direct efficiency gains for the livestock producer.

In tipping forage trailers, the cylinder provides force and stability for body tipping, allowing silage to be unloaded in hard-to-reach areas with less physical effort and greater logistical agility. It also integrates with auxiliary implements — silo maintenance platforms, fence mowers, and yard cleaners — broadening equipment versatility and positioning Helesul as a complete solutions provider for agriculture.

The cylinder operates by hydraulic pressure transmitted to the piston through ISO VG 46 mineral or equivalent synthetic fluid, converting hydraulic energy into precise linear motion. The polished internal finish of the SAE 1020/1045 drawn steel tube reduces friction, minimizes fluid heating, and improves energy efficiency — resulting in lower fuel consumption during extended feed unloader operations.

The double-layer chrome-plated SAE 1045 steel rod protects against abrasive wear and the corrosive action of silage organic acids. High-performance polyurethane and NBR seals maintain integrity across temperatures from -20°C to +80°C, preventing hydraulic oil contamination and ensuring reliable operation in extreme winter or tropical summer conditions.

The articulated mounting system with metal bushings absorbs misalignments and vibrations typical of uneven terrain, protecting pins and bearings while significantly extending the service life of the assembly. The optional integrated check valve prevents unintended retraction in case of momentary pressure loss, ensuring operational safety and structural stability of elevated machine components.

With modular, interchangeable components, replacing seals and bushings is fast and requires minimal specialized technical intervention. This reduces machine downtime, lowers maintenance costs, and keeps farm productivity at peak levels — concrete, measurable advantages that directly impact the profitability of implement manufacturers and livestock producers alike.

Low Lead Time: Agility That Drives Competitiveness

Helesul operates with agile manufacturing and logistics processes, ensuring delivery schedules that drastically reduce production stoppages on the customer's assembly line. With strategic raw material inventory, flexible production capacity, and punctuality-driven order management, Helesul ensures that implement manufacturers never halt production due to cylinder shortages — a critical advantage in seasonal markets like livestock machinery, where delays mean lost sales.

Engineering Support: Technical Partnership from Design to After-Sales

Helesul provides dedicated engineers for specification, customization, and technical support throughout the entire product lifecycle. From defining stroke, bore size, and mounting type to jointly developing solutions for unique applications, the technical team accompanies the customer at every stage — including assembly team training, detailed installation manuals, and on-site assistance for pilot machine commissioning. More than a supplier: a true engineering partner.

Superior Manufacturing Quality

Every Helesul cylinder is manufactured with high-grade carbon steel, rigorous machining processes, and millimeter-precise dimensional control. The specific anti-corrosive treatment for prolonged contact with acidic silage and high humidity outperforms conventional cylinders in service life and reliability. Manufacturing warranty on all products and remote and on-site technical support reinforce Helesul's commitment to excellence in every component delivered.

Customization Flexibility

Helesul's application engineering develops custom solutions in stroke, bore, mounting type (eye-eye, eye-flange, clevis-clevis), and optional accessories — serving everything from prototypes to large production runs. Magnetic position sensors and pressure transducers compatible with CAN Bus controllers are available for integration with agricultural automation and telematics systems, preparing customer implements for the future of digital agriculture.

Complete Portfolio and Consolidated Agricultural Experience

With decades of presence in the agricultural hydraulic components market, Helesul offers an integrated solution portfolio that extends beyond cylinders — covering the full range of hydraulic needs for implement manufacturers. This experience translates into deep knowledge of Brazilian and international field demands, a capillary technical assistance network, and rapid response capability to the requirements of an ever-evolving market.
