Helesul hydraulic cylinders for accessibility platforms are strategically applied across diverse inclusive mobility contexts. In rear elevating platforms of urban and intercity buses, the cylinder controls with millimeter precision the platform's descent and ascent, guaranteeing exact leveling with the vehicle floor and sidewalk, even on irregular terrain. This precision is crucial for ensuring safety during boarding of wheelchair users, elderly passengers, and those using crutches or canes.
In school vans, minibuses, and adapted transport vehicles, the cylinders enable compact designs without compromising load capacity (up to 300 kg), essential for accommodating motorized wheelchairs and attendants. The robust construction and progressive hydraulic damping at the end of stroke reduce structural impacts, preserving vehicle integrity and providing smooth movements that instill confidence in users.
Specialized road implements, such as mobile health units, social assistance vehicles, and accessible tourism services, also benefit from this solution. The cylinders ensure safe and rapid access in itinerant operations, with high reliability on long-distance routes and frequent use under adverse road conditions.
The Helesul hydraulic cylinder operates through controlled fluid pressure, transmitting linear force to the piston that moves the rod. This operation is widely recognized for its smoothness and reliability, allowing repetitive cycles without accelerated wear. The reinforced dual-seal system eliminates premature leaks, maintaining platform stability at any working position and raising passenger safety to superior levels.
The hard-chrome-plated rod with surface hardening treatment resists urban corrosion—moisture, road salt in coastal regions, pollution—and mechanical wear, extending maintenance intervals by up to 40% compared to conventional rods. Progressive hydraulic damping at the end of stroke reduces structural impacts on the platform and chassis, providing smooth movements that inspire user confidence and preserve component integrity.
Additionally, adjustable stroke and customizable mounting options allow perfect integration to different platform geometries, facilitating OEM and retrofit projects without complex structural modifications. Compatibility with position sensors and safety valves easily integrates into electro-hydraulic control systems, allowing automatic locking at intermediate positions and fault signaling for enhanced operational protection. Compact design and low weight optimize space in vans and minibuses, contributing to central hydraulic efficiency.
