Construction Machinery

Large Components, Structural Steelwork

Requirements

What this industry demands.

In construction machinery manufacturing, massive component dimensions are subjected to heavy mechanical stresses: booms, slewing mechanisms, and frames must remain robust for years while staying within tight manufacturing tolerances to ensure attachments and hydraulics fit precisely. In addition, welded assemblies made of high-strength structural steels like S355 require dimensionally stable post-weld machining. Our solution: single setups for components up to 24 m in length, documented cutting data for structural steel, and in-house metrology that inspects even large-format workpieces without third-party service providers.

Strengths

Our strengths here

Scale as Standard

Components up to 24 m in length and 160 t in weight are daily business for us, not the exception.

Single Setup

Large frames and structures are completely machined in a single setup rather than moved between multiple machines.

Structural Steel Expertise

S355 and comparable structural steels with documented cutting data and inspected welds.

In-House Metrology

Gantry coordinate measuring machines and laser trackers inspect even oversized components without third-party providers.
