Product Technology
The SB40 triangle rock hammer adopts medium-light breaker dedicated integrated forging and vibration reduction hydraulic matching technology:
- Triangle support frame integral alloy casting, overall stress relief annealing to eliminate internal residual stress, long cycle work without deformation or cracking;
- Alloy cylinder blank integral hot forging, CNC ultra-precision inner and outer wall turning, smooth inner wall to guarantee unobstructed hydraulic oil circulation;
- Core piston overall quenching & tempering heat treatment, outstanding anti-fatigue performance to adapt frequent start-stop municipal and quarry work;
- 85mm chisel surface hardening treatment, improve surface wear resistance while retaining internal anti-breakage toughness;
- Medium-capacity built-in accumulator for pressure stabilization, balance hydraulic fluctuation of 4–7 ton excavator hydraulic system;
- Every finished SB40 triangle breaker passes medium-pressure endurance test, cyclic striking aging test and frame anti-vibration inspection before delivery.
Production Process
Alloy steel raw material incoming inspection → Triangle support frame integral casting & stress relief annealing → Integrated cylinder hot forging forming → CNC inner & outer wall precision turning polishing → Piston quenching tempering heat treatment → 85mm chisel surface hardening treatment → SB40 built-in directional valve assembly → Composite high-pressure dustproof seal installation → Triangle buffer support assembly matching → Medium-pressure hydraulic matching calibration test → Cyclic striking aging test → Frame anti-vibration deformation inspection → Anti-rust anti-corrosion coating treatment → Shockproof packaging & global sea-air delivery

FAQ
Q1: What tonnage excavator fits SB40 triangle hydraulic breaker?
A1: This SB40 triangle rock hammer is specially customized for 4–7 ton medium-small crawler excavators, perfectly matching medium-pressure hydraulic output of this tonnage diggers without overload damage to main hydraulic pump.
Q2: What’s the core difference between triangle SB40 and straight SB40 breaker?
A2: Triangle frame adopts three-point force dispersion structure with excellent shock absorption, stable operation in narrow limited space; straight hammer lacks multi-point support, generates violent vibration during continuous rock breaking, easy to shake and fatigue damage.
Q3: Can standard SB40 85mm chisel and spare parts be used on this triangle SB40 breaker?
A3: Yes. This SB40 triangle hydraulic rock breaker follows universal SB40 industry standard, all 68mm chisels, seal kits, nitrogen charging valves and pins are fully interchangeable.
Q4: Is SB40 triangle hammer suitable for basement and narrow alley demolition projects?
A4: Highly applicable. Compact body plus triangular anti-shock frame, it can flexibly enter low basements, narrow urban alleys and small foundation trenches where construction space is limited.
Q5: Will the triangular support frame deform after long-term cyclic striking?
A5: No. The triangle bracket adopts integral casting and stress relief annealing process, internal stress completely eliminated, maintain stable shape without deformation or crack under long cyclic medium-hard rock breaking work.
