Atlas Copco HC 409

HC 409 and HC 920 hydraulic-compactor attachments feature hoses that are centrally routed to prevent contact with working surfaces. The hoses are positioned to mimic the company's breaker configuration so that a compactor and breaker can be used on the same carrier without having to cross hoses when changing attachments. At 900 pounds, the HC 409 delivers an 8,000-pound impulse force and produces 2,100 cycles per minute. It fits carriers in the 4- to 9-metric-ton weight class and has a 24- by 36-inch plate. At 1,600 pounds, the HC 920 has an impulse force of 16,000 pounds and delivers 2,200 cycles per minute. It fits carriers in the 9- to 20-metric-ton weight class and has a 28- by 40-inch plate. Prices: HC 409 is $5,541; HC 920 is $9,671.
