These heavy-duty double-acting hydraulic rams are engineered to withstand 10,000 PSI of pressure, delivering the precise, high-force performance required by modern plant protection machines. Designed for tasks like lifting spray booms, adjusting nozzle heights, and deploying protective covers, their double-acting mechanism ensures smooth, bidirectional movement even under variable loads. Built with premium steel components and reinforced seals, they resist corrosion from pesticide residues and field moisture, maintaining reliable operation in harsh agricultural environments. Manufactured to OEM standards, these rams ensure a perfect fit and consistent performance, helping to maximize the efficiency of your crop protection equipment.
Agricultural hydraulic cylinders act as the "powerful arms" of farm implements, adaptable to various demanding field scenarios. From tractor hitch lifting to harvester header adjustment, from seeder trench depth control to sprayer boom deployment, they deliver stable and robust power. Their rugged design ensures long-lasting performance amid mud, dust, and humidity fluctuations. As the fundamental enabler of multifunctionality, high efficiency, and intelligent control in machinery, they are key drivers in the advancement of precision agriculture.

High-pressure hydraulic cylinders (≥20MPa) apply to heavy-duty agricultural scenarios: heavy tractor hitch systems (lifting subsoilers), large loader buckets (handling straw), combine harvester header lifting, silage baler compression mechanisms, and heavy subsoiler 破土 mechanisms. They use high thrust to adapt to high-load, intensive operation needs.
1,Smooth Start-up and Stop: Operate the control valve smoothly, avoiding rapid reversals or sudden starts and stops to reduce impact loads on the hydraulic cylinder and system.
2,Avoid Extreme Off-center Loads: Ensure the load acts along the hydraulic cylinder's axis as much as possible, avoiding excessive lateral forces or eccentric loads to prevent piston rod bending or abnormal wear of seals.
3,Prohibit Overtravel: Ensure the design limits of the working device are reliable. Do not allow the hydraulic cylinder piston to extend or retract excessively beyond the mechanical limit to prevent internal impact damage.
4,Monitor Operating Status: During operation, observe whether the hydraulic cylinder moves smoothly, whether there are abnormal noises, vibrations, or jamming. Keep the piston rod clean; remove any adhering materials promptly.
