The GBN45TL hydraulic breaker, also identified as the GBM180L, is a powerful silenced T-Series hydraulic breaker designed for compact and mid-size excavators. With a 250 kg operating weight and 60 mm tool, it provides a strong balance of impact power, durability, and carrier compatibility for demanding construction and demolition applications. It is designed for excavators in the 3 to 5.5 ton class.
The GBN45TL is built for operators who need greater impact performance from a breaker that remains suitable for smaller excavators. Its 60 mm moil-type tool delivers an impact energy of 493 joules (364 ft-lb) with an impact rate of 500–1,000 blows per minute.
The silenced breaker has an operating weight of 250 kg (551 lb), making it suitable for excavators in the 3 to 5.5 ton range. The manufacturer lists approximately 5 tons as the suitable operating class.
The GBN45TL requires a hydraulic oil flow of 30–60 L/min and operates at a breaker pressure range of 100–130 bar (1,450–1,885 psi). Proper hydraulic flow and pressure matching should be confirmed with the carrier excavator before installation.
The breaker is supplied with two tools — chisel and moil — along with hoses, couplers, and a hitch bracket manufactured to suit the excavator, providing a ready-to-work attachment package. :contentReference[oaicite:2]{index=2}
Suitable for demanding demolition work where increased impact energy is required while maintaining compatibility with compact and mid-size excavators.
Designed for construction applications involving concrete breaking, masonry removal, structural work, and general hydraulic breaking.
The 60 mm moil-type tool and 493 J impact energy provide substantial breaking performance for suitable concrete, masonry, and other construction materials.
Designed for excavators in the 3–5.5 ton range, with approximately 5 tons listed as the suitable operating class.
