This SB131 box type hydraulic rock breaker adopts fully enclosed box frame design, with unique protective advantages compared with triangle frame breaker:

• Integral thickened sealed box shell, fully wrap internal cylinder and valve parts, block dust, mud and flying rock collision, greatly extend service life of internal spare parts;
• Split thickened cylinder body, partial disassembly maintenance available without removing whole hammer from excavator, save mine maintenance downtime;
• Standard 165mm high alloy forged chisel, high hardness and strong toughness, resistant to tip collapse and abrasion during long hard rock breaking;
• Reinforced built-in high-pressure valve group, optimized internal oil channel, stable circulation without heat accumulation under non-stop mining operation;
• Multi-layer buffer shock absorption structure between box frame and cylinder, reduce vibration transmission to excavator arm and main hydraulic pump;
• 100% interchangeable with all Soosan 165 / SB131 series accessories, chisel, seal kits, nitrogen charging valve easy global procurement.

The SB131 box frame rock hammer adopts mine-grade enclosed box manufacturing and heavy hydraulic matching technology:

1. Box frame integrally cast with high tensile alloy steel, overall stress relief annealing to eliminate internal stress, avoid frame deformation after long-term impact;
2. Split cylinder blank vacuum alloy steel forging, CNC ultra-precision inner wall polishing to guarantee smooth hydraulic oil flow;
3. Core piston integral quenching & tempering heat treatment, excellent impact fatigue resistance to adapt all-day mining continuous operation;
4. 165mm chisel vacuum infiltration alloy hardening process, balance surface wear resistance and internal anti-fracture toughness;
5. Fully enclosed dust-proof sealing structure at box assembly gap, prevent fine mineral dust entering internal hydraulic parts;
6. Each finished SB131 box breaker undergoes high-pressure endurance test, 24-hour continuous striking aging test and dustproof sealing inspection before delivery.

This universal SB131 box type hydraulic rock breaker is widely used for new machine assembly and old hammer replacement of 30–45 ton heavy mining excavators.

Main applicable working scenes: open-pit mine granite & basalt hard rock mining, large quarry stone splitting, mountain blasting residue cleaning, super large foundation hard rock removal, heavy industrial concrete demolition. It is the optimal replacement for triangle breakers used in high-dust mine areas, widely matched for mining enterprises, stone yards and large engineering construction teams.
