Hydraulic Power Packs Power-On-Demand System These hydraulic packs power a wide range of hydraulic handheld tools for construction, utility and demolition projects.

In addition, a twin-pack model has the capability to supply power to two tools at the same time. The LP9-20 and LP13-20 DE are fitted with 9-hp and 13-hp Honda gasoline engines, respectively. Both feature a power-on-demand system that increases the engine speed only when a tool is engaged. Atlas Copco Construction Tools; 413/746-0020; www.us.atlascopco.com
