12m Long Reach Boom & Arm For Sany 125

Before production, we run finite element stress simulation for this 12m Long Reach Boom & Arm for Sany 125. Key high-stress areas are reinforced with extra plate material to avoid structural deformation under extended reach work.

Each pin hole is precision-bored and fitted with wear-resistant copper bushings to slow down routine abrasion.

Hydraulic hose routes are carefully optimized, lowering the risk of pipe friction damage while the boom swings.

It delivers steady digging performance on site, so operators do not reposition the excavator often and get jobs done faster.

We are a professional manufacturer of excavator attachments, specializing in long reach booms, grapple saws, hydraulic hoses and more. We own our independent welding and machining workshops. Every boom set goes through step-by-step inspection during production. We can provide CE certification, and all our manufacturing follows ISO quality standards.

Q1: Can you make long reach boom for my excavator? Which models are compatible?
A: We customize for most brands: Komatsu, Caterpillar, Volvo, Sany, XCMG, Doosan, LiuGong etc. It is NOT universal for all machines. Please send us excavator model, required reach/depth, pin size and working condition for engineering check.


Q2: Do I need extra counterweight for long reach boom?
A: Usually yes. Longer boom increases front load. Our engineer will calculate and recommend matched counterweight to keep machine stable. It depends on boom length and your excavator weight.


Q3: What lengths can you supply?
A: Common sizes: 12m,15m,18m,20m,22m,24m. We support fully custom length according to your project.
