SB20 Triangle Hydraulic Rock Breaker Triangle Frame Mini Excavator Rock Breaker

This lightweight compact SB20 triangle hydraulic rock breaker is a mainstream small triangle frame mini excavator hydraulic hammer and standard universal SB20 triangle rock hammer, a lightweight 1.5-2 ton digger attachment equipped with standard 45mm chisel for light municipal and garden construction. As classic triangle support small hydraulic breaker specially designed for micro excavators, this SB20 triangle hammer adopts triangular multi-point shock-absorbing frame structure, balanced stress distribution and stable low-frequency striking performance, perfectly matching 1.5–2 ton mini excavator low-pressure hydraulic output. Different from straight mini breakers, triangle frame design effectively disperses slight vibration generated during frequent light striking, reduces shaking of small digger arm and avoids frame deformation under long intermittent operation. It uses integrated wear-resistant cylinder and anti-fatigue 45mm alloy chisel, solves the defects of straight hammer such as poor stability and easy frame shaking in narrow space, cuts daily maintenance frequency, and is the most practical triangle hydraulic breaking accessory for micro excavator indoor, courtyard and municipal light demolition work.

The SB20 triangle rock hammer adopts mini light-duty breaker dedicated integrated casting and low-vibration hydraulic matching technology:

1. Triangle support frame integral lightweight alloy casting, stress relief annealing to eliminate internal residual stress, long intermittent use without deformation;
2. One-piece light alloy cylinder precision CNC turning, smooth inner wall to ensure smooth low-pressure hydraulic circulation;
3. Mini piston integral quenching & tempering heat treatment, excellent anti-fatigue performance for frequent start-stop garden and municipal work;
4. 45mm chisel surface hardening treatment, balance wear resistance and flexibility to adapt light breaking scenes;
5. Mini built-in accumulator for pressure stabilization, smooth pressure fluctuation of micro excavator low-pressure system;
6. Every finished SB20 triangle breaker passes low-pressure endurance test, intermittent striking aging test and frame anti-shake inspection before leaving factory.

This universal SB20 triangle hydraulic rock breaker is widely used for new machine assembly and old straight hammer replacement of 1.5–2 ton mini excavators.

Main applicable working scenes: indoor wall demolition, villa courtyard rock cleaning, rural narrow road repair, small residential foundation trimming, municipal greening renovation, loose slope stone clearing. It is an ideal replacement for straight mini breakers with unstable frame shaking, widely supplied to micro digger rental shops, small municipal construction teams and garden engineering companies.

Compared with traditional SB20 straight hydraulic breakers, triangle frame SB20 rock hammer has targeted lightweight construction strengths:

1. Three-point triangular force dispersion frame, strong anti-shake performance, stable operation in narrow indoor and courtyard space;
2. Ultra-light whole machine weight, no hydraulic overload to 1.5–2 ton low-power mini excavator, protect original machine well;
3. Simple disassembly and maintenance, small spare parts loss, low daily maintenance cost;
4. Fully interchangeable with all standard SB20 accessories, no extra stocking cost for parts suppliers;
5. Soft and uniform striking force, suitable for fine light demolition without excessive damage to surrounding structures;
6. Small size with flexible movement, factory direct sale, cost-effective for small batch garden and municipal projects.

A1: This SB20 triangle rock hammer is exclusively designed for 1.5–2 ton mini crawler excavators, perfectly matching low-pressure hydraulic output of micro diggers without overload damage to the main pump.

A2: Triangle frame adopts three-point force dispersion structure with good anti-shake effect, stable operation in narrow space; straight hammer has no multi-point support, easy to shake during light striking, poor stability in limited space.

A3: Yes. This SB20 triangle hydraulic rock breaker follows universal SB20 industry standard, 45mm chisel, seal kits, nitrogen charging valves and pins are 100% interchangeable.

A4: Absolutely suitable. Lightweight small body + anti-shake triangular frame, it can flexibly enter narrow indoor rooms, courtyards and small trenches where construction space is limited.

A5: No. The triangular support frame undergoes integral stress relief annealing treatment, internal stress is eliminated, stable shape, will not deform or shake after long-term intermittent garden and municipal light breaking work.
