Excavator Factory | Yanmar Construction Equipment production in Japan.
Yanmar compact construction equipment gives you maximum performance in urban development projects.
Cities are cramped, complex spaces, so whichever way you look at it, you're going to need better quality equipment, equipment with better power,
better maneuverability, better fuel efficiency, better environmental credentials, and better durability.
It's the capabilities of our people and their hearts, tenaciously committed to developing and making better quality equipment that delivers that quality.
The number of parts required for a single machine is around 400. The parts required for each process are sorted into sets and supplied to each line.
Presswork turns steel plates into parts. Massive presses up to 1,000 tons and 3D lasers are used to fabricate all sorts of parts, from those weighing 130 kilograms, to ones small enough to fit in the palm of your hand. We utilize Yanmar Construction Equipment's proprietary pressing technology to form 1.6 millimeter steel plates into deep concave shapes, like that of a saucepan.
Welding thin steel plates from 2.3 to 4.5 millimeters thick. Generally, handling parts that require exterior quality, like covers, or parts that need to be airtight, like hydraulic fluid tanks.
Painting. Singlehandedly performing the entire process, from mixing and preparing the paint to finishing the fine details.
The task is to make the exterior of the machine - its “face” - look
as good as possible.100 to 170 parts per machine are sorted into three lines by drying temperature: high, normal, and low. Mixing paint for rustproofing and painting the fine areas that machines cannot handle is all done by hand. As a process that affects the exterior quality of the product, it requires a great deal of skill to cover the entire surface evenly with a coat only 0.06 mm thick.
Backhoe assembly.
Currently, there are 16 models in the backhoe product line. The specifications are different, for the countries where they will be used, and as requested by customers, so in fact there are over 200 different patterns. The assembly of all of these on a single line is one of the unique features of Yanmar Construction Equipment. Each process takes around 7 minutes, passing on the machine to the next process without any delays.
Loaders and carriers assembly.
Painted parts, purchased parts, and other parts are sorted into eight processes for assembly to complete the loaders and carriers. In order to improve our production efficiency, we introduced a conveyor line in 2016. There are fewer parts compared to backhoes, so while the number of employees is smaller, each member of this elite team plays a pivotal role with many responsibilities keeping them on their toes as they work.
