Features
The 190 mm chisel and 100–140 BPM impact rate provide strong performance for hard rock, concrete, and large materials.
The side-mounted triangular configuration helps distribute impact forces and provides stable control during heavy breaking.
The design uses fewer components, helping reduce potential failure points and making routine inspection and maintenance easier.
The low mounting position and optimized geometry make it easier to sweep and clear broken material after impact.

FAQ
The BLT-190 is designed for 45–55 ton excavators. Beilite lists models including Caterpillar 345/349D, Doosan DX480/DX490/DX520, JCB JS450, Hitachi ZAX450/470/490, and Sany SY465/SY465H-8/SY485.
The recommended working oil flow is 240–290 L/min, with a 250–270 bar working pressure and 300 bar relief pressure.
Regularly inspect the chisel, wear components, mounting connections, hydraulic hoses, and lubrication points. The BLT-190 uses a 1¼-inch oil hose, and timely inspection of wear parts helps maintain reliable breaking performance.
