| 摘要： | HYDRAULIC BREAKERS ARE BECOMING smarter and heading to a breakout future. The Infrastructure Investment and Jobs Act (IIJA) should bring plenty of work for hammers as they chip through structurally deficient old bridges, bust away outdated pavement, and clear out the old for new construction. Maximizing breaker productivity for these projects starts with proper pairing of the hammer, carrier, and application. Matching the right hydraulic breaker to a job is a balancing act of considerations. The core machine considerations for matching a breaker to its carrier are the machine's operating weight, its hydraulic flow characteristics-operating pressure, hydraulic flow rate, auxiliary flow rate-its overall lift capacity, and the geometry of the carrier's boom design, all of which contribute to operating stability. Breaker manufacturers and OEM compatibility charts provide a range of mechanical and operating requirements proven to pair specific sized carriers efficiently with various breakers. These listings are a good starting point and provide a proven foundation on which to add other considerations such as the job's material type, time constraints, and the contractor's budget. "Correctly matching the breaker to the available carrier is crucial to optimize efficiency as well as protect the contractor's equipment," said Joe Tedesco, president of Gorilla Hammers/ Tech Hydraulics. Tedesco says selecting the right hammer for a job begins with the carrier's size and its oil output. |
