The Epiroc EC 90T is a 1,380 lb (625 kg) Essential range hydraulic breaker for excavators and other carriers in the 19,800–33,100 lb (9–15 t) class. It drives a 3.54 in. (90 mm) working tool at 600–950 bpm (AutoStart mode), on 21.1–29.1 gpm (80–110 l/min) of oil flow at 1,885–2,175 psi (130–150 bar) and up to 37 HP (28 kW) of hydraulic input.

Epiroc builds the EC range as a durable, reliable breaker for day-to-day jobs. Hybrid technology uses an integrated nitrogen piston accumulator for constant impact energy, safe start-up and smooth operation. VibroSilenced Plus isolates the percussion mechanism from the breaker box on non-metallic suspension and seals every opening, which lowers noise and vibration, and the internal control valve and EnergyRecovery system raise operating efficiency. On the EC 90T, the monoblock design combines cylinder and tool holder in one section with no tie rods and a replaceable piston liner for cost-effective repairs; the full-length floating tool bushing allows quick exchange with standard hand tools; double tool retainer bars hold the working tool; percussion chamber ventilation uses a built-in check valve to reduce dust intake into the tool guiding area and percussion chamber. This CL configuration comes with the ContiLube II self-bleeding automatic lubrication pump for continuous greasing of the working tool. Moil points, chisels and blunt tools are under Epiroc working tools, and the EC 90T parts breakdown lists the seal and label kits. See the full Epiroc hydraulic breakers range.
