Hydraulic Cylinder for Sprayers

Trailed Boom Sprayers

Helesul cylinders power the active boom suspension, enabling fast height and tilt adjustments for crops such as soybeans, corn, and wheat. Uniform distribution of crop protection products is ensured even on undulating terrain, reducing input waste and maximizing agronomic efficacy along the entire treated swath.

High-Capacity Self-Propelled Sprayers

Used in folding, articulation, and automatic leveling of booms up to 36 meters wide, Helesul cylinders provide fast response integrated with electronic control systems. They deliver stability at high operational speeds, supporting shifts of 12 to 16 hours with minimal structural wear.

Pendulum Suspension and Safety Locks

Cylinders control lateral and vertical pendular movement, absorbing terrain oscillations on uneven ground. They also actuate safety locks during road transport between fields, protecting structural integrity and preventing unintended movement.

Roadside Vegetation Control

In trucks and tractors used for herbicide application along road corridors, Helesul cylinders control boom extension, retraction, and lateral positioning safely near traffic, meeting the specific operational requirements of this segment.

Operating Principle and Precise Control

Helesul cylinders convert hydraulic pressure into precise linear force. The automatic boom-leveling system compensates for terrain irregularities in real time, maintaining a uniform distance between the boom and the crop canopy. The progressive end stop absorbs mechanical shocks, protecting joints from fatigue caused by repetitive impacts.

Anti-Contamination Seals and Longevity

Specialty seals made of NBR, polyurethane, or Viton maintain integrity under continuous exposure to crop protection products, dust, and moisture, extending preventive maintenance intervals. Chrome-plated rods with a minimum coating thickness of 25 µm provide superior resistance to corrosion and friction wear in chemically aggressive environments.

Modular Design and Reduced Operating Costs

The modular design enables quick replacement of seal kits and wear components without requiring complete cylinder removal, directly reducing machine downtime. Adjustable mounting options simplify installation across different sprayer brands and models.

Automation-Ready Integration

Cylinders can be supplied with provisions for magnetic or potentiometric position sensors and pressure switches, enabling full integration with electronic boom controllers and precision agriculture management systems.

1. Low Lead Time — Fast Delivery, Uninterrupted Production

Helesul maintains agile manufacturing and logistics processes, supported by strategic inventory and flexible production capacity to meet urgent demands. The average lead time for custom prototypes is 4 to 6 weeks after technical approval, with serial supply schedules aligned with your production plan, ensuring uninterrupted operations.

2. Dedicated Engineering Support — From Concept to Homologation

Helesul engineers support every project from initial specification to final homologation, including complete hydraulic circuit sizing — pumps, valves, hoses, and circuits — as well as validation testing and comprehensive technical documentation. This consultative support eliminates rework and accelerates product development.

3. Customizable Engineering for Every Project

We develop cylinders tailored to each implement’s specifications, with stroke, bore, seal material, connections, and finish adapted to the customer’s requirements. This flexibility reduces development time and eliminates the need for field modifications.

4. Superior Chemical Resistance

Careful selection of sealing materials — NBR, polyurethane, or Viton — and protective coatings provides superior compatibility with crop protection products, foliar fertilizers, and adjuvants, ensuring greater operational reliability and a lower total cost of ownership.

5. Quality and International Compliance

All cylinders are manufactured in accordance with ISO 9001, using drawn and honed SAE 1020/1045 steel and chrome-plated rods with a minimum coating thickness of 25 µm. They are designed for continuous, severe-duty cycles, with appropriate safety factors for daily shifts of up to 16 hours.
