PC-11 Series Cab Made to Order Only
We are the world’s only manufacturer that has independently developed a complete operator cabin solution specifically for Komatsu PC‑11 series excavators. Through years of engineering research, structural optimization, and OEM‑level integration, we have created a full‑range cabin platform compatible with PC130‑11 up to PC550‑11, covering the entire 13–55 ton class.
Each cabin is designed with reinforced safety structures, enhanced visibility, improved operator comfort, and precise mounting points that match Komatsu’s original specifications. Our engineering process ensures seamless installation, stable performance, and long‑term durability in demanding working environments such as mining, construction, forestry, and earthmoving.
This product is manufactured strictly on an order basis (Made‑to‑Order). Cabins are produced according to customer requirements, machine configuration, and regional specifications. Custom options—including interior trim, wiring harness layout, seat configuration, glass type, and accessory mounting—are available to meet different market needs.
Trusted by global distributors, fleet owners, and equipment rebuilders, our PC‑11 series cabins provide a reliable, high‑quality replacement solution for international markets.
