Tramac has introduced its newest light-range breaker, the SC-42, into the SC-Series line of hydraulic hammers.

The SC-42 expands the SC-Series to a total of eight breakers to fit carriers from 2,200 to 30,900 lbs. (938 to 14,016 kg).

The SC-42 is for carriers from 11,000 to 26,500 lbs. (5 to 12 t) and has an operating weight of 967 lbs. (438 kg). With an operating pressure of 1,812 psi (125 bar), the SC-42 has a flow range of 14.5 to 26.4 gpm (55 to 100 Lpm). This hydraulic breaker is rated at an impact energy class of 1,250 ft.-lbs. and has an impact frequency range of 550 to 1,450 blows per minute. The tool diameter is 3.31 in. (8.4 cm).

The SC-42 includes many of the SC-Series features, such as 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.

If needed, the breaker can quickly be disassembled without special tools, reducing maintenance time and cost. The SC-42 features an internally mounted retaining pin clip that makes tool change-out quick and easy and reduces clip fatigue. The wear items are field-replaceable so the SC-42 can function with less downtime.
