Hydraulic cylinder for trailer attachments

The Helesul Hydraulic Cylinder is widely used in agricultural trailer dumping operations, enabling quick and efficient unloading of soybeans, corn, wheat, and other grains. In field operations, it reduces operation time by up to 40% compared to manual systems, increasing daily productivity and allowing more transport cycles. Adjustable stroke precision ensures that dump angle is optimized for each load type, maximizing unload speed without damaging the implement.

In implement carrier trailers and road-legal dump trailers, the cylinder provides sufficient force to move up to 20 tonnes safely and controllably, even when hauling agricultural inputs, gravel, and construction materials. Dual sealing and retention system guarantee no oil leakage during long-distance hauls, maintaining operational efficiency and preventing unexpected downtime. Sprayer implements also benefit: the cylinder controls boom lift and fold with millimeter precision, guaranteeing equipment protection during road transport and accuracy in application.

Lift platforms on service trailers and control systems for harrows, scarifiers, and subsoils use the cylinder for lifting and locking during field operations. The robustness of reinforced trunnions and heat-treated internal bore withstand repetitive dynamic loads without structural failure, offering versatility for multiple applications in a single machine.

The Helesul Hydraulic Cylinder operates on the principle of force transmission through pressurized fluid. The internal piston, manufactured from hardened SAE 1045 steel, receives pressure up to 210 bar and transmits controlled linear motion through the chrome-plated rod. The dual sealing system (high-performance polyurethane rings) eliminates leakage even at maximum pressure, preserving hydraulic circuit efficiency.

The direct benefit to the operator is a reduction in corrective maintenance by up to 50%. The chrome-plated and polished rod minimizes friction and premature wear, while the hardened bore resists corrosion and impact in harsh environments—essential characteristics for machines working in the field exposed to moisture, fertilizers, and abrasive material. The integrated check valve (optional) keeps the load suspended safely, increasing operator and equipment protection in case of circuit failure.

In daily operation, the cylinder offers quick and precise response. Adjustable stroke allows exact adaptation to different dump heights, eliminating manual adjustments and rework. The ability to operate in any position—vertical, horizontal, or inclined—and within temperature range -20°C to +80°C guarantees consistent performance regardless of weather conditions. This translates to greater machine availability, fewer unexpected stops, and higher return on investment.

Fuel economy is also significant: the low internal resistance of the Helesul cylinder substantially reduces hydraulic energy consumption, decreasing demand on the tractor or machine's pump system, resulting in measurable fuel savings in continuous operations

Low Lead Time: Helesul maintains agile manufacturing processes and strategic inventory of cylinders in various sizes and configurations, guaranteeing fast deliveries that reduce your customer's production downtime. With manufacturing facilities sized to respond to demand peaks and integrated logistics, Helesul ensures you receive the cylinder on schedule without compromising quality. This punctuality is critical in seasonal agricultural operations, where delays of days can mean significant harvest losses. Our flexible production also enables quick customizations, adapting the cylinder exactly to your project specifications without delays.

Engineering Support: Helesul offers specialized technical support from specification phase through post-sale support. Our dedicated engineering team works with customers to specify the correct cylinder—calculating ideal stroke based on dump angle, distance between attachment points, and load type. We provide technical training for assembly and maintenance teams, illustrated manuals in English, remote support during first installation, and ongoing support to resolve operational challenges. This technical proximity transforms Helesul from supplier to strategic partner in your implement's success.

Certified Quality and Extended Warranty: All Helesul hydraulic cylinders are manufactured according to international standards ISO 6020 and ISO 6022, with ABNT NBR certification for road applications. Each unit undergoes pressure testing, leak testing, and structural resistance verification before leaving the factory. We offer extended 24-month warranty for applications within specified parameters, covering manufacturing and material defects. This confidence in product quality protects your investment and provides operational peace of mind.

Extended Service Life and Simplified Maintenance: Our cylinders operate up to 30% longer than conventional models due to advanced surface treatment, high-tech seals, and hardened internal bore that resists corrosion and impact. Modular design allows quick seal component replacement without complete cylinder disassembly, reducing maintenance downtime by up to 50%. This means your customer spends less time in the workshop and more time in the field, increasing fleet productivity.

Energy Efficiency and Operational Versatility: The low internal resistance of the Helesul cylinder significantly reduces hydraulic energy consumption, decreasing pump system demand and delivering proven fuel savings in continuous operations. The cylinder operates in any mounting position and within wide temperature range (-20°C to +80°C), offering versatility for multiple applications in a single implement. This design-agnostic flexibility allows manufacturers to develop more compact and efficient machines, reducing production costs and increasing product appeal in the market.
