Light Hydraulic Breakers and the SC Series
Tramac's Light Hydraulic Breakers are designed for light to medium breaking operations on rock, concrete, asphalt and industrial materials. Ideal for in-plant and exterior tasks such as gut-out, machine slab demolition, and light curb and gutter breaking. The SC Series is specially designed to function three ways - as breaker, bucket, and compactor - with quickly interchangeable accessories, requiring only one operator.
Carrier: for mini-excavators, backhoes and skid steers
SC Series: Interchangeable Light Breaker/Bucket/Compactors
- Patented steel ring system for changing accessories: ring locks the tool retainer and bushing, protects greasing system. Included multiple-use tool removes the ring, releasing bushing and tool instantly.
- AutoPower automatic pressure regulator and sealed nitrogen chamber mean optimum power across a broad flow range, with high back pressure.
- Simplified interior mechanics for easy maintenance and cost control: no tie rods, few moving parts, quick disassembly. No extra hydraulics needed when attaching bucket or compactor accessories.
- Cylindrical ergonomic shape is excellent for tight spaces. Striking assembly is suspended within the cylindrical housing, not in contact with it, greatly reducing noise and potential for overheating.

More Light Hydraulic Breakers
- Fast, simple installation, plugging into the carrier's auxiliary circuit -- no special hydraulic lines or extra valves needed.
- Superior "Soft Start" control: breakers start in low impact mode allowing the operator to create a small cavity in the material to hold tool in place as full impact power is applied.
- High impact and frequency mean high production: lighter material breaks better with a high striking rate.
- Internal recoil absorber reduces vibrations to the carrier. Super Metro-Silenced (SMS) versions of non-SC models available for noise-sensitive work locations.
- Exclusive built-in pressure regulator maintains correct operating pressure for maximum performance.
