Segment‑oriented Industry Solutions
Chassis & Frame Industry
Industry Pain Points
Chassis assemblies for excavators, loaders, rollers, mining trucks and forklifts are mostly built from Q235 / Q355 medium‑heavy steel plates. Conventional flame or plasma cutting creates large heat‑affected zones and plate warping, which hurts final assembly accuracy. A large number of scattered mounting holes require separate secondary drilling processes, bringing accumulated position tolerance. Large‑size chassis demand stable long‑time‑running machine performance.
- Thermal deformation from flame cutting causes assembly mismatches
- Separate drilling steps increase labor and cycle time
- Frequent drawing revisions for different machine models raise fixture costs
- Heavy large‑format workpieces require rigid machine‑bed capacity
Our Laser Solution
High‑power heavy‑duty laser cutting handles multi‑model chassis blanking for various construction machinery. Contours plus all mounting holes can be finished in one procedure, removing secondary drilling work. Controlled low‑heat input minimizes plate warping. Heavy‑duty machine beds support oversized parts, suitable both for small‑batch prototype changes and mass‑volume production runs.

- Reduced thermal deformation to keep chassis flatness
- No custom fixtures, fast adaption for revised chassis drawings
- Stable continuous operation for large‑volume machinery orders
Boom & Arm Structures
Industry Pain Points
Boom and arm assemblies for excavators, truck cranes, truck‑mounted cranes and aerial work platforms are bent‑and‑weld heavy‑plate components. Bevel cuts, special notches and pin‑hub holes involve multiple separate operations. Frequent drawing changes across machine models push up fixture expenses. Plate distortion before welding creates uneven joint gaps and poor weld quality.
- Traditional bevel machining is time‑consuming
- Many custom arm variants require repeated fixture rework
- Plate deformation leads to inconsistent welding gaps
- Mixed‑thickness plates increase process complexity
Our Laser Solution
Laser processing completes bevel edges, notches and pin holes in a single cut. Program updates replace physical fixture modifications for new arm revisions. Limited heat‑input preserves plate flatness for consistent bending and welding fit. Fits boom‑type parts for cranes, excavators and aerial‑access equipment.

Counterweight & Ballast Parts
Industry Pain Points
Counterweight housings for excavators, forklifts, rollers and cranes are thick‑plate welded boxes filled with ballast material. Outer profiles, lifting lugs and connection holes differ heavily between equipment models. Flame‑cut edges produce heavy burrs requiring extensive grinding. Dimensional errors prevent proper box‑shell closing during welding assembly.
- Heavy manual grinding workload for flame‑cut thick‑plate edges
- Wide variation of counterweight outlines across machine series
- Dimension deviations cause poor fit during box‑shell welding
- High‑volume repetitive production requires stable part consistency
Our Laser Solution
High‑power laser delivers stable thick‑plate cutting for counterweight shells. Outer contours, lifting holes and fastening holes are formed together. Clean cut surfaces reduce grinding work. Rapid drawing adaptation supports many machinery series, and high batch consistency guarantees welding‑assembly fit for counterweight housings.
