SANY has once again raised the bar in construction machinery with the introduction of the STR50E, the world’s first fully electric, 4.5-tonne light tandem roller. Designed with sustainability and performance at its core, the STR50E is a pioneering step in the move toward zero-emission road construction equipment.
A First in Its Class – 100% Electric Drive and Vibration
The SANY STR50E isn’t just electric powered — it’s the first in its weight class to feature fully electric drive and vibration systems. This innovation provides smoother operation, lower noise levels, and significantly reduced emissions, making it perfect for urban environments and eco conscious contractors.
Powered by Industry-Leading Battery Tech from CATL
At the heart of the STR50E is a 60kWh cobalt-free lithium-iron-phosphate battery, sourced from CATL, one of the largest and most trusted battery manufacturers in the world. This next generation battery delivers:
4 to 6 hours of continuous operation under real world conditions
Efficient energy regeneration when decelerating or changing direction — just like a Formula 1 car
Safe, reliable performance with an onboard charging system for convenience on site
Built with the Operator in Mind
SANY hasn’t just focused on the technology under the hood. The STR50E also boasts:
An ergonomically designed operator’s platform with swivel seat and side-to-side movement for enhanced visibility
Dual electronic control levers for precise, responsive handling
A comfortable, intuitive workspace that helps reduce operator fatigue during long shifts
Leading the Charge in Zero Emission Machinery
The STR50E is a landmark machine for SANY Road Machinery, marking its first foray into electric compaction equipment. It joins the already successful SY19E and SY215E electric excavators, with more all-electric models planned for release in 2025.
Whether you’re a council contractor, road maintenance team, or civil construction business looking to reduce your carbon footprint — the SANY STR50E Electric Roller delivers power, performance, and sustainability in one smart package.
