No power needed: purely mechanical hydraulic system boosts medical equipment safety & reliability

SMILE medical hydraulic cylinders and pumps adopt pure mechanical hydraulic driving design, requiring no electricity, no wiring, and no electronic control components. 

This core feature completely avoids equipment failures caused by power failure, circuit damage, and electronic component aging. Whether in emergency rescue, outdoor transfer, or ward power-off situations, SMILE hydraulic units can work stably at any time. 

With purely mechanical linkage and integrated overload protection, it delivers safer and more reliable lifting performance for hospital beds, stretchers and medical trolleys, becoming a stable backup power source for medical equipment.
