Hydraulic-powered H-Model vacuum lifting systems from Vacuworx International have the same performance of Vacuworx diesel-powered lifters with lower operating costs. The hydraulic option is available for the Vacuworx MC 5 and all RC Series systems. They attach easily to excavators and backhoes with a dedicated auxiliary hammer circuit, with or without a coupler system. The environmentally friendly hydraulic lifting systems produce near zero noise and air pollution, providing the ideal solution for construction sites within city limits or with strict emission guidelines. Hydraulic operation provides improved start-up performance in cold weather and eliminates the possibility of fuel freezing in extreme conditions. The hydraulic lifters are lightweight, allowing farther reach and greater total lift capacities. 866/664-3450; www.vacuworx.com.
