Heavy Equipment Fabrication

The experts at KOIKE have worked for decades with top heavy steel fabrication companies.  Our combination of know-how and products allow our customers to stay ahead of the competition. The types of cutting and welding done for products such as mining vehicles, agriculture equipment, shipbuilding, and offshore platforms require unique solutions.  The large ranges of KOIKE standard and customized equipment are designed to meet the rigorous demands of our customers.

Large gantry cutting machines, such as laser, plasma, oxy-fuel and waterjet cutting, are used to cut very large parts for frames, dump beds, excavator arms, blades, and lifting eyes.  Often, these parts are made of very thick steel and require specialized bevels for welding in the next stage of heavy steel fabrication. Large gantry cutting machines have the option to add plasma bevel cutting and oxy-fuel bevel cutting to the machine. Laser and water jet cutting machines can be equipped with three-dimensional bevel cutting heads.

Portable semi-automated cutting and welding equipment is employed in difficult areas that are often done by hand.  Productivity in these areas can often be increased by three-fold.

The handling of large weldments and parts can be done safely by using positioning equipment, such as gear driven positioners, head and tailstock sets, and turning rolls. Welding positioners reduce workload on overhead cranes and other handling equipment. Welds are done more efficiently and defects are reduced. Savings can also be seen in the reduction of wire and gas usage.
