Breaker Function
Configure the primary circuit for compatible single-acting breaker work.
Excavator Auxiliary Hydraulics
Breaker, Shear and Rotate Hydraulic Kits
Prepare one excavator for compatible breaker, shear, and rotating-attachment functions with coordinated high-flow primary plumbing, low-flow rotation, matched controls, and application support.
Discuss This Application
Breaker, Shear & Rotate
Maximum auxiliary flexibility from two coordinated circuits.
HKX Breaker, Shear & Rotate kits combine a selectable single- or double-acting primary circuit with a double-acting secondary circuit. The primary circuit handles compatible high-flow breaker or shear functions while the secondary circuit provides lower-flow attachment rotation.
The published configuration uses 5,000 PSI-rated tubing and hoses for both circuits, matching left- and right-hand controls, and secondary plumbing sized for 20 GPM or less. HKX must confirm the excavator and attachment requirements before final configuration.
Published HKX Specifications
Understand the standard configuration before final selection.
These legacy HKX values describe the standard kit basis. Final component selection and machine settings require application confirmation.
- 1 / 2-Way + 2-Way
- Selectable primary and double-acting secondary
- High + Low Flow
- Secondary circuit published at 20 GPM or less
- 5,000 PSI
- Published tubing and hose rating for both circuits
- Upgradeable
- Designed for a broad compatible attachment mix
Attachment Applications
Select the primary tool function and retain independent rotation.
The system is intended for excavators that need a broader mix of compatible one-way, two-way, and rotating attachment functions.
Shear Function
Select double-acting primary operation for compatible shears and processors.
Rotation Function
Operate attachment rotation from the independent low-flow secondary circuit.
Coordinated Controls
Use matching left- and right-hand joysticks to manage the required functions.
System Features & Options
Coordinate two circuits around the machine and attachment.
HKX reviews the excavator, primary attachment demand, rotation requirements, oil sources, and control strategy before defining the final system.
Configuration details
Controls
Matching left- and right-hand joysticks.
Recommended Options
Proportional joystick, case drain, and SAE four-bolt flange tube and hose connections.
Routing & Connections
Plumbing routes to the end of the arm, terminating with quarter-turn ball valves on the primary circuit and quick disconnects on the secondary circuit.
Application & Installation Planning
Match the system to the excavator and attachment.
Accurate machine and attachment details help HKX identify the appropriate circuit, components, controls, routing, and installation support.
-
01
Identify the excavator
Provide the manufacturer, model, serial number, current hydraulic equipment, and any relevant machine options.
-
02
Define the attachment
Confirm the attachment make and model, required functions, flow, pressure, case drain, and connection requirements.
-
03
Select controls and routing
Review operator controls, oil sources, component placement, boom and arm routing, and service-access needs.
-
04
Prepare and support the installation
Use the packaged components and instructions, with HKX technical assistance available for installation and future parts identification.
