Product Information

The WL12000HE is the workhorse of Winco’s Big Dog portable generator series. The WL12000HE will save you time and money giving your company a competitive advantage over crews using other portable generators. The 15 gallon fuel tank provides 9 hours of run time at full load so you won’t have to take unscheduled breaks to refuel your industrial generator. The factory installed lifting bar makes it easy to get this generator on and off the roof while the pneumatic tires on the four wheel dolly kit make maneuvering this generator easy. The WL12000HE is the preferred portable generator in the flat top roofing industry. It is durable enough to handle the hours while providing clean power for sensitive equipment.
