HYDRAULIC CYLINDER FOR VEHICLE-MOUNTED CRANE

Helesul's hydraulic cylinder serves multiple critical functions in vehicle-mounted cranes. In boom elevation, it controls lifting angle with millimeter precision, enabling safe operation at heights exceeding 20 meters. In synchronized extension of telescopic sections, it enables expanded reach and operations in difficult-to-access locations. In stabilizer leg actuation, it ensures perfect vehicle leveling before lifting, uniformly distributes loads, and prevents tipping on uneven terrain.

In slew control of the superstructure, it enables smooth and controlled rotation, facilitating precise positioning of heavy loads in confined spaces of urban construction and industrial assembly. In auxiliary winch systems, it controls cable release and retraction with rapid response and high braking capacity for suspended loads. This versatility makes Helesul cylinder a complete solution for crane manufacturers demanding technical excellence across multiple critical applications.

The hydraulic cylinder operates by converting hydraulic pressure into controlled linear force through a high-precision piston. The dual sealing system eliminates oil leakage, significantly reducing maintenance costs and minimizing environmental impact. The integrated check valve guarantees safe load retention in case of hydraulic system failure, preventing critical accidents and protecting operators and assets.

The high-resistance chrome rod provides superior protection against corrosion and wear, dramatically extending service life even in harsh port and humid climate environments. Thermal treatment of internal components increases mechanical strength and impact absorption capacity, essential for intensive crane duty cycles. The integrated hydraulic damping system smooths movement initiation and completion, reducing structural vibrations and protecting crane structure.

The adjustable-length design permits precise adaptation to specific application requirements, optimizing space utilization and maximizing lifting height. These direct benefits result in measurable operational savings, greater equipment availability, and unquestionable safety for work teams.
