As one of the mother factories in the KOBELCO CONSTRUCTION MACHINERY GROUP,
the Itsukaichi Factory aims to be the number 1 producer in the world
through the highest standards of safety, quality, and productivity.
There, we are responsible for the production of medium, large hydraulic excavators
and environmental recycling machines in the range of 7 to 220 tons.
The safe and comfortable working environment is a kind of our pride to manufacturing.
These ideas are encompassed in the Itsukaichi Factory’s “Smart & Clean” concept.

Steel fabrication
Seeing machines in action is my motivation
After welding and machining the frame,
it is transported by conveyor to the painting process.
Painting
To create better products, we need mutual bond based on trust
The painting process, including the under and over coats,
shot blasting, and drying, is all done on an assembly line.
Sub assembly
Our approach to manufacturing is the careful execution of each step
We assemble the piping for all the devices such as the engine and pump.
Following the introduction of AGVs (Automated Guided Vehicles), delivery efficiency (in-house) increased by 50%.
Body assembly
Focusing on post-processes also has an effect on product quality
After all of the devices are assembled, the body of the lower and upper, and attachments must be assembled.
Lower/upper structure docking
The most important things are working together and breathing together
Here, the lower and upper frames are docked.
The swing bearing is tightened using a specialized device.
Main assembly
We must be constantly thinking about safety
Mounting the counterweight and cab gives
the hydraulic excavator its final form.
The Itsukaichi Factory has implemented various ideas to keep a factory eco-friendly. For example, painting the floor and pillars white increases the natural light, and using double-folded plates in the ceiling increases heat insulation by 5°C. These decrease our energy expenditure.
Rigging and testing
To be the last defense, never let defects slip by
Final inspections are performed to test hydraulic leaks,
functional issues, etc. Decals are then affixed, completing the manufacturing process.
Shipping
A beautiful finish leads to customer satisfactions
The final preparations are performed
so that the excavator can be delivered to the customer.
