The GBN300EL hydraulic breaker is a heavy-duty E-Series hydraulic breaker engineered for demolition, rock breaking, trenching, and major construction applications. Featuring a powerful 2,200 kg silenced operating weight and a 150 mm tool diameter, the GBN300EL is designed for excavators in the 24–36 ton range.
The GBN300EL is built for operators requiring high-impact efficiency and heavy performance on medium-to-large excavators. As part of the GB E-Series, it delivers an impressive 4,176 Joules (3,080 ft/lb) of impact energy for demanding job sites.
With a robust 2,200 kg (4,850 lb) silenced operating weight, the GBN300EL is engineered for carrier machines operating between 24 and 36 tons.
The breaker utilizes a heavy-duty 150 mm moil-type tool (weighing 162 kg), providing superior strength and penetration for reinforced concrete, bedrock, and large excavation projects.
The GBN300EL delivers a versatile impact rate of 300–650 blows per minute, ensuring fast material fracturing and high productivity.
Operating at a breaker pressure of 160–180 bar, it requires a hydraulic oil flow of 150–190 L/min. Always ensure the carrier machine's hydraulic setup aligns with system specifications prior to mounting.
Featuring an advanced gas/hydraulic system with an accumulator pressure of 60 bar, the GBN300EL helps cushion pressure spikes and protects the excavator's hydraulic system during heavy breaking operations.
Ideal for breaking down reinforced concrete structures, foundations, bridge decks, and heavy masonry work.
With 4,176 Joules of impact energy, the GBN300EL provides efficient secondary breaking in quarries, benching, and hard rock trenching.
Delivers dependable breaking capacity for major pipeline trenching, road construction, and foundation site preparation.
Specifically tailored for medium-to-large excavators in the 24–36 ton range (30-ton recommended class).
