The updated TranzVolt G2 surpasses previous models. With an extended two-year warranty, the TranzVolt G2 system is designed to withstand demanding job site conditions. This eco-friendly and cost-efficient product now utilizes AmSteel-Blue high-performance 12-strand single braid of 100% DyneemaA® fiber cable, which has extremely low stretch, superior flex fatigue, and wear resistance, and no longer requires fuel and oil. The TranzVolt G2 Roofing Kit is a great tool for lifting materials, such as shingles, rolled goods, tools, and bulk roofing materials, in tight spots or when low-noise ordinances are being enforced. It carries material 44 ft. high at a rate of 2 ft. per second, reaching the height of a two-story building in under 25 seconds. Using two standard Milwaukee Brand 18V rechargeable batteries, the Roofing Kit lifts up to 250 lbs. for eight hours.
