The RY series from Harrington is a heavy-duty electric wire-rope hoist  built for industrial overhead lifting.  The RY hoists are configured as ultra-low-headroom trolley hoists: that means the hoist and trolley are designed to minimize required overhead clearance, making them suitable for facilities where vertical space is limited. They are designed for heavy loads — capacity range for the RY series is typically 3 to 10 tons.
