KOMATSU Hydraulic Systems
A mature Komatsu program supported by deep technical resources.
HKX established its collaborative relationship with Komatsu in 2000. The program brings machine-specific engineering, packaged components, installation documentation, and technical support together for a broad range of excavator applications.
Current HKX resources extend from the full Komatsu kit catalog to focused machine pages such as the PC220LC-12, giving customers multiple ways to move from machine identification to a workable hydraulic solution.

Attachment Possibilities
Configure the hydraulic functions the work requires.
HKX can help connect Komatsu excavators with single-function, combination, rotating, priority-flow, and specialized attachment applications.
Multi-Function Systems
Combined circuits for attachments that require multiple controlled hydraulic functions.
Rotation & Priority Flow
Options for rotating tools and demanding applications that require deliberate flow management.
Custom & Conversion
Purpose-built planning for uncommon attachments, legacy machines, and specialized operating requirements.
Machine & Attachment Engineering
Machine-specific detail, demonstrated on the PC220LC-12.
The HKX PC220LC-12 system shows how routing, controls, mounting, and attachment capability can be coordinated around a specific Komatsu platform.
What HKX plans around
- Low-profile routing: Hydraulic lines follow the machine structure for protection and service access.
- Prepared mounting: Purpose-built brackets and hardware support a clean installation.
- Integrated controls: The control system is planned with the machine and attachment functions together.
Installation-Ready Systems
A complete path from machine details to working hydraulics.
HKX prepares Komatsu hydraulic systems to reduce field fabrication, clarify installation, and support the machine after the kit ships.
