DAVIDSON, N.C. ” June 2, 2008 ” Tramac introduces the V1800 into its line of heavy-range hydraulic breakers. The V1800 features the critical characteristics that contractors have come to know and expect from Tramac.
The V1800 is for carriers from 44,100 to 77,200 pounds (20 to 35 metric tons) and has an operating weight of 3,913 pounds (1775 kilograms). With an operating pressure of 2,394 pounds per square inch (165 bar), the V1800 has a flow of 37 to 58 gallons per minute (140 to 220 liters per minute). This hydraulic breaker is rated at an impact energy class of 6,000 foot-pounds and has an impact frequency range of 310 to 500 blows per minute. The tool diameter is 5.5 inches (140 millimeters).
A one-piece bushing is one of the features incorporated into the V1800. The principal wear parts, including the bushing, are field-replaceable without dismounting the breaker from the carrier or removing any tie rods. Up to 2.5 gallons per minute (9.5 liters per minute) can be diverted through the integrated flow control to protect the breaker from carrier overflow. A high back-pressure tolerance of 363 pounds per square inch (25 bar) allows the V1800 to be easily installed on a wide range of carriers.
As with all Tramac heavy-range breakers, the V1800 maximizes productivity and reduces the transfer of potentially damaging energy back to the carrier with variable-speed breaker technology. This technology senses changes in material hardness and automatically adjusts the breaker to the optimal combination of impact energy and striking rate. Additionally, an energy recovery system recycles recoil energy and adds it to the next blow.
Maintenance for the Tramac heavy-range breaker line is minimal due to a blank fire protection feature that prevents metal-to-metal contact that can damage a hammer. The heavy-duty, abrasion-resistant cradle also protects the hammer and its internal components from damage and excessive wear. The cradle is also silenced to reduce noise on the jobsite.
