Tramac has introduced its newest light-range breaker, the SC-42, into the SC-Series line of hydraulic hammers and the V2500 and V1800 into its line of heavy-range hydraulic breakers.
The SC- 42 expands the SC-Series to a total of eight breakers to fit carriers from 2,200 to 30,900 pounds, and is specifically designed the skid steer, backhoe loader, and mini and mid-size excavator markets.
The SC-42 is for carriers from 11,000 to 26,500 pounds and has an operating weight of 967 pounds. With an operating pressure of 1,812 pounds per square inch, the SC-42 has a flow range of 14.5 to 26.4 gallons per minute. This hydraulic breaker is rated at an impact energy class of 1,250 foot-pounds and has an impact frequency range of 550 to 1,450 blows per minute. The tool diameter is 3.31 inches.
The V2500 is for carriers from 59,500 to 88,200 pounds and has an operating weight of 5,555 pounds. With an operating pressure of 2,248 pounds per square inch, the V2500 has a flow range of 46 to 66 gallons per minute. This hydraulic breaker is rated at an impact energy class of 8,000 foot-pounds and has an impact frequency range of 300 to 500 blows per minute.
The V1800 is for carriers from 44,100 to 77,200 pounds and has an operating weight of 3,913 pounds. With an operating pressure of 2,394 pounds per square inch, the V1800 has a flow range of 37 to 58 gallons 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.
The SC-42 includes many of the SC-Series features including an automatic pressure regulator that ensures that the breaker operates at maximum performance on all carriers, regardless of flow variations. Upper and lower shock absorbers isolate the breaker from the carriage, reducing noise and vibrations transferred to the carrier and the operator. The SC-42 also has an energy chamber, which features a diaphragm design that holds its
charge without requiring regular nitrogen refills.
As with all SC-Series breakers, maintenance is easy with the SC-42 because
it has fewer moving parts and if needed, the breaker can quickly be disassembled without special tools. The SC-42 features an internally-mounted retaining pin clip that makes tool change-out quick and easy and reduces clip fatigue.
Several new features have been incorporated into the V2500 design. A one-
piece bushing is among the new features and a large tool diameter of 6.3
inches. 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 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 allows the V2500 to be easily installed on a wide range of carriers.

As with all Tramac heavy-range breakers, the V2500 and V1800 comes 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.
