Adding auxiliary hydraulics to an excavator significantly increases its versatility, allowing it to operate a wide range of attachments.
Why Add Auxiliary Hydraulics to an Excavator?
Excavators are essential machines across various industries, including construction, demolition, mining, forestry, and oil & gas. Their versatility comes from their hydraulic system, which powers critical components like the boom, arm, bucket, and tracks.
To maximize functionality, many operators add auxiliary hydraulic circuits to run attachments like thumbs, grapples, breakers, and tilt buckets. This guide covers key steps, safety precautions, and the best hydraulic components for a seamless installation.
Preparing for Auxiliary Hydraulic Installation
Before installing auxiliary hydraulics, it’s important to plan carefully to ensure efficiency and safety.
Key Safety Measures:
✅ Lower any attached implements before removing hydraulic fittings to prevent accidental drops.
✅ Use an oil collection basin to catch spilled hydraulic fluid.
✅ Plan a proper hose route to prevent pinching, rubbing, or snagging on tree limbs or debris.
✅ Gather all necessary components, such as ball valves, elbows, and fittings, ensuring they have the correct thread type.
✅ Select hose and fitting sizes that match the attachment’s hydraulic flow rate (standard-flow or high-flow) to prevent pressure loss and overheating.
Step-by-Step Guide to Installing Auxiliary Hydraulics
1️⃣ Remove Existing Hydraulic Lines – Carefully detach the necessary lines from the excavator’s hydraulic circuit.
2️⃣ Install 3-Way Ball Valves – Add a valve to allow the machine to switch between multiple attachments.
3️⃣ Connect the Hoses – Attach hydraulic hoses to the new circuit, ensuring secure connections.
4️⃣ Test for Leaks and Functionality – Once installed, pressurize the system and check for leaks or operational issues.
5️⃣ Route and Secure the Hoses – Use clamps and protective sleeves to prevent damage from movement and external elements.
By turning the ball valve, operators can switch between attachments, such as powering a thumb or tilting a bucket, with a simple joystick command.
Why Choose Gute Hydraulic Components for Excavator Upgrades?
Faster’s ISO 16028 quick-release couplings (FFH series) are a top choice for auxiliary hydraulics on excavators. Their high flow rate minimizes pressure drops and overheating, while Zinc-Nickel plating ensures corrosion resistance in harsh environments.
For attachments, Faster’s Connect-Under-Pressure (CUP) couplings (3FFH series) are highly recommended. These couplings make it easy to connect hydraulic lines even when there’s trapped pressure, reducing operator effort and downtime.
