The GBN400TL hydraulic breaker is a large heavy-duty F-Series hydraulic breaker designed for demanding demolition, quarrying, excavation, rock breaking and major construction applications. With a substantial 2,400 kg silenced operating weight and a large 155 mm tool diameter, the GBN400TL is designed for excavators in the 28–40 ton range.
The GBN400TL is built for operators who require serious hydraulic breaking performance from large excavators. As part of the GB F-Series, it uses an accumulator-assisted design to support powerful and consistent breaking performance in demanding applications.
With a substantial 2,400 kg (5,291 lb) silenced operating weight, the GBN400TL is designed for large carrier machines operating between 28 and 40 tons.
The breaker uses a large 155 mm moil-type tool, providing the strength and working capacity required for major demolition projects, hard rock, foundations and difficult excavation conditions.
The GBN400TL delivers an impact rate of 280–550 blows per minute, combining a powerful impact range with the substantial operating mass required for heavy-duty breaking applications.
The breaker requires a hydraulic oil flow of 160–240 L/min and operates at a breaker pressure of 160–180 bar. The carrier excavator's hydraulic system should always be checked to ensure it can provide the required flow and pressure.
As part of the F-Series accumulator-type breaker range, the GBN400TL incorporates an accumulator designed to assist the power stroke and help protect the carrier hydraulic system from pressure shock during operation.
The GBN400TL is an ideal choice for contractors working on large-scale demolition, quarrying, hard rock breaking, major excavation and infrastructure projects where a powerful breaker is required for a large excavator.
Designed for demanding demolition applications involving reinforced concrete, foundations, structural elements and large construction materials.
The substantial breaker weight and 155 mm tool make the GBN400TL well suited to breaking hard rock and other difficult materials encountered in quarrying and large-scale site preparation.
Provides powerful hydraulic breaking capability for major excavation, road construction, foundations, utility work and infrastructure projects involving difficult ground conditions.
Designed for large excavators in the 28–40 ton range, subject to confirmation of the carrier machine's hydraulic flow, pressure and attachment compatibility.
