Case Study: Optimized Demolition Boom for CAT336 with 2.5-Ton Shear
Project Background: A South American contractor needed to replace their underperforming 22m CAT336 demolition boom that struggled with: ⚠️ Excessive strain when using 1.67-ton shear (vertical positioning) ⚠️ Limited lifting capacity for heavier attachments ⚠️ Premature wear on standard Q355B structure   Engineering Solution Redesigned 19m High-Reach Demolition Boom Parameter Original Design Upgraded Version Length 22m 19m Material Full Q355B Q690D (upper/lower) + Q355B (side plates) Arm Weight 4,445kg (boom) Optimized distribution Cylinders Standard Reinforced Ø220mm Max Attachment 1.67t 2.5t (rotation shear/grapple)     Key Improvements: ✔ 19% shorter length for better load management ✔ Q690D steel in critical stress areas (yield strength ↑40%) ✔ Custom hydraulic circuits for smoother operation Technical Breakdown Structural Enhancements Boom/Stick: Upper/Lower Plates: 25mm Q690D Side Walls: 20mm Q355B Pivot Points: 80mm diameter pins (from 65mm) Bronze bushings with grease channels   Hydraulic System New Cylinders: Bore: 220mm (original 200mm) Pressure rating: 350bar Revised Valve Settings: 15% slower extension speed Pressure relief at 280bar Performance Gain: ▸ 2.5-ton shear operation now stable at full extension ▸ Expected service life extended by 60%   Why This Matters for Your Project Lessons Learned Shear Weight vs. Reach: Every 1-ton attachment weight ↓ recommended length by 3m Material Selection: Q690D adds 15% cost but ↑ lifespan 2X in demolition Cylinder Sizing Rule: Minimum 220mm bore for 2.5t+ attachments Pro Tip: Request our free load calculator to simulate your configuration   Expert Support:   Kaiping Zhonghe Machinery Manufacturing Co.,LTD.
