The hydraulic-powered post drivers from Atlas Copco, West Springfield, Mass., provide stable, powerful, high-speed driving solutions for a variety of post sizes. Capable of producing 1,500 blows per minute, the post drivers are suited to applications such as driving road barrier tubes, profiles, signposts, fences and a wide range of anchors. The trigger-level activation of the 68-lb LPD-T post driver provides the operator with hands-on control of the unit, while the remote valve activation of the LPD-RV, a 64-lb post driver, enables the operator to engage the unit from a switch in the hydraulic line. These activation options increase the versatility of the drivers. The drivers can be used on open-center hydraulic systems or, with the optional remote-control valve, on closed-center hydraulic systems.
