The GBN30TL hydraulic breaker, also identified as the GBM120L, is a compact silenced T-Series hydraulic breaker designed for small to mid-size excavators and demanding construction, demolition, concrete, and general breaking applications. Its 180 kg operating weight and 53 mm tool provide a balanced combination of impact performance and carrier compatibility for excavators in the 2.5 to 4.5 ton class.
The GBN30TL is designed for operators who need increased hydraulic breaker performance while maintaining compatibility with compact and mid-size excavators. Its 53 mm moil-type tool delivers an impact energy of 318 joules (235 ft-lb) with an impact rate of 600–1,100 blows per minute.
The silenced GBN30TL has an operating weight of 180 kg (397 lb), making it suitable for excavators in the 2.5 to 4.5 ton range. The manufacturer lists approximately 3 tons as the suitable operating class.
The breaker requires a hydraulic oil flow of 25–50 L/min and operates at a breaker pressure range of 90–120 bar (1,305–1,740 psi). Matching the excavator's hydraulic flow and pressure to these requirements is important for proper breaker operation.
Suitable for demolition applications requiring more impact performance from a compact hydraulic breaker mounted on a small to mid-size excavator.
Designed for construction applications involving hydraulic breaking, concrete removal, masonry work, and general material reduction.
The 53 mm moil-type tool and 318 J impact energy provide a practical configuration for breaking concrete, masonry, and other suitable construction materials.
Designed for excavators in the 2.5–4.5 ton range, with approximately 3 tons listed as the suitable operating class.
