Q1: Which excavators is this SB121 triangle breaker compatible with?
A1: This SB121 triangle hydraulic breaker is designed for 20–30 ton class excavators. It is a heavy-duty SB121 excavator rock breaker hammer, high-performance 155mm side type hydraulic breaker, rugged SB121 triangular demolition breaker, versatile SB121 excavator breaker attachment, efficient hydraulic rock breaker for 20-30 ton excavator and reliable OEM SB121 breaker assembly, compatible with CAT, Komatsu, Hitachi, SANY, XCMG and other mainstream brands.
Q2: What is the difference between triangle type and box-type breakers?
A2: Triangle type breakers have an open frame with easy maintenance, better heat dissipation and lower cost, ideal for open-air mining, quarrying and road construction. Box-type breakers are fully enclosed with lower noise and better dust protection, suitable for urban areas and heavy mining. Our SB121 triangular demolition breaker balances performance and cost for medium-to-heavy outdoor applications.
Q3: What chisel types are available for this breaker?
A3: We offer multiple chisel options for this 155mm side type hydraulic breaker: pointed chisel for hard rock, flat chisel for concrete and asphalt, blunt chisel for secondary crushing, and moil point chisel for general purpose. All chisels are made of 42CrMo alloy steel with four-sided forging and deep induction hardening.
Q4: Is installation complicated? Do you provide guidance?
A4: Installation is straightforward with standard excavator hydraulic lines. We provide detailed installation manuals, video guidance and 24/7 online technical support. We can also customize the mounting bracket to match your exact excavator model.
Q5: What is your warranty and after-sales policy?
A5: We offer 12-month warranty for the main machine and 6-month warranty for wearing parts (chisels, seals, etc.). If there is a quality problem within the warranty period, we provide free replacement parts and technical solutions. We also supply all spare parts for long-term after-sales support.
