The GBN170TL hydraulic breaker is a heavy-duty T-Series breaker engineered for demanding excavation, construction, demolition, concrete, rock, and general breaking applications. With a substantial 1,200 kg silenced operating weight and a 125 mm tool, the GBN170TL is designed for excavators in the 15–20 ton range, with 17 tons listed as the suitable excavator class.
The GBN170TL is engineered for contractors who require serious hydraulic breaking performance from larger excavators. Its substantial construction and 125 mm moil-type tool make it well suited to demanding rock, concrete, demolition, and excavation work.
With a 1,200 kg (2,646 lb) silenced operating weight, the GBN170TL provides a heavy-duty attachment package for excavators from 15 to 20 tons. The manufacturer's suitable excavator class is 17 tons.
The breaker delivers an impact rate of 420–730 blows per minute. This variable impact range allows the breaker to deliver powerful and controlled performance across different materials and working conditions.
The GBN170TL requires a hydraulic oil flow of 100–120 L/min and operates at a breaker pressure range of 150–170 bar. Proper hydraulic flow and pressure matching should be confirmed with the carrier excavator before installation.
The GBN170TL features GB's robust T-Series internal-valve breaker design. The breaker incorporates a large gas chamber, high-quality piston construction, optimized cylinder design, and a low-resistance valve system designed to support efficient and stable operation.
The model also benefits from GB's dual tool-retainer arrangement, which helps maintain correct tool alignment while distributing tool wear. The breaker housing uses reinforced wear protection and vibration-absorbing components to support durability during demanding operation.
From the GBN170T and above, the T-Series incorporates a valve adjuster that allows the hammer's impact rate to be adjusted, providing additional flexibility when matching breaker performance to the application.
Designed for demanding demolition projects where larger excavators require substantial hydraulic impact power for breaking concrete, masonry, foundations, and structural materials.
The 125 mm tool and heavy-duty breaker construction make the GBN170TL suitable for breaking rock and other hard materials encountered during excavation and site preparation.
Provides powerful breaking capability for excavation, trenching, road preparation, foundation work, and other projects where hard ground must be reduced efficiently.
Designed for excavators in the 15–20 ton range, with 17 tons listed as the suitable operating class.
