SB131 Triangle Hydraulic Rock Breaker Triangle Type Excavator Hydraulic Hammer for Mining Hard Rock Breaking

This heavy-duty SB131 triangle hydraulic rock breaker is a mainstream large mining triangle type rock hammer and standard SB131 excavator hydraulic breaker, serving as high-performance large excavator demolition attachment equipped with 165mm heavy chisel for hard rock mining. As classic triangle frame hydraulic breaker, this SB131 triangle hammer features triangular shock-absorbing support frame, strong anti-vibration performance and stable continuous striking capacity, perfectly matching 30–45 ton heavy excavators for quarry and open-pit mine construction. Different from box type breakers, triangle structure effectively disperses impact vibration, reduces pressure loss and avoids frame deformation under long-term heavy load. It adopts thickened split cylinder body and high alloy 165mm chisel, solves common faults such as frame crack, weak impact force and frequent vibration damage of ordinary mining breakers, greatly improving hard rock breaking efficiency and lowering long-term mine maintenance cost.

The manufacturing of SB131 triangle type rock hammer adopts mine-grade heavy-duty hydraulic breaker integrated forging and vibration reduction technology:

1. Triangle support frame integral cast alloy steel, overall stress annealing treatment to eliminate internal stress, avoid deformation under long impact;
2. Split cylinder high alloy steel vacuum forging, CNC ultra-precision inner wall polishing, smooth hydraulic oil circulation;
3. Core piston overall quenching & tempering heat treatment, strong impact fatigue resistance for all-day mining operation;
4. 165mm chisel vacuum infiltration alloy hardening craft, balance surface wear resistance and internal toughness;
5. Large capacity built-in accumulator, boost instantaneous striking force and stabilize hydraulic pressure fluctuation;
6. Each finished SB131 triangle breaker passes high-pressure burst test, 24-hour continuous striking aging test and frame vibration resistance inspection.

A1: This SB131 triangle rock hammer is exclusively designed for 30–45ton heavy crawler excavators, perfectly matching high-pressure hydraulic output of large diggers without overload damage to main pump.

A2: Triangle multi-point force dispersion structure greatly reduces vibration concentration, effectively prevent frame crack and weld fracture under long hard rock mining; box type frame bears concentrated stress and is easy to deform and crack.

A3: Yes. This SB131 triangle hydraulic rock breaker follows universal Soosan 165 industry standard, 165mm chisel, seal kits, nitrogen charging valves and pins are fully interchangeable.

A4: Absolutely. Equipped with thickened 165mm high alloy forged chisel and enhanced internal valve group, it has powerful impact force and ultra wear resistance, ideal for long-term granite and basalt open-pit mining.

A5: Not complicated at all. Split cylinder allows partial disassembly for internal piston and valve maintenance, no need to remove the whole hammer from excavator, saving plenty of mine maintenance time and labor cost.
