HITACHI Hydraulic Systems
Hydraulic attachment support developed over decades.
HKX has manufactured hydraulic kits for Hitachi excavators since the early 1990s. That experience informs how the system is planned around the machine, attachment functions, hydraulic demand, and installation environment.
Machine-specific components and clear documentation help technicians add capability while preserving practical routing, service access, and a clean finished installation.

Attachment Possibilities
Configure the hydraulic functions the work requires.
HKX can help connect Hitachi 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
Configured for the attachment, not just the machine name.
HKX plans the hydraulic functions and controls around how the Hitachi excavator will be used in the field.
What HKX plans around
- Function matching: Single-, dual-, and multi-function needs guide the circuit design.
- Durable routing: Tubes, hoses, clamps, and mounts are planned for demanding work.
- Field support: HKX specialists remain available for installation and service questions.
Installation-Ready Systems
A complete path from machine details to working hydraulics.
HKX prepares Hitachi hydraulic systems to reduce field fabrication, clarify installation, and support the machine after the kit ships.
