Ideal for narrow trench work, the Model 500 Ho-Pac delivers 30 percent more impact energy, says the company. It also has a longer base plate, a four-function valve, three motor options, and oil splash bearing lubrication. Designed for mini-excavators, rubber-tired backhoes, and trenchers with backhoe attachment, the unit can compact 2- to 4-foot lifts. It operates with an impulse force of 3,940 pounds at 2,000 cycles per minute with a minimum gpm of 9, 14 or 18 from the carrier.
