ご依頼背景

“I’m embarrassed by how it looks on site…”
A customer consulted us about their KOBELCO SK135SRD backhoe. This frequently used machine had become noticeably scratched and rusted.

While appearance may seem secondary at demolition sites, the customer expressed a desire to “have it properly repaired, as our business partners see it.” Additionally, due to the risk of further corrosion and parts deterioration from rust progression, we proposed sheet metal painting repair, which the customer approved.

Having previously requested repairs on other heavy machinery, the customer returned with the encouraging feedback: “The work was fast and the finish was excellent, so I wanted to ask you again.”

[Key Repair Points]

Sheet metal techniques that preserve the base material, minimizing putty use
→ Achieves both strength and appearance while ensuring durability.

Natural color matching using genuine paint
→ Results in a finish where repair marks are barely noticeable.

Thorough surface preparation for extended paint film life
→ Careful primer application to prevent rust recurrence.

[For Those with Similar Concerns]

Many operators of machines like the SK135SRD face issues with dents and rust on exterior panels.
Such cosmetic problems are particularly common at demolition and forestry sites where contact is frequent.
Similar issues are often seen in models such as the Komatsu PC138US and Hitachi ZX135US.

Leaving damage unaddressed with the mindset “it still runs…” can lead to major repairs down the line.
Early sheet metal painting protects both the machine’s lifespan and its professional appearance.

“Can this condition still be repaired?”
