Our engineering team combines advanced fluid power concepts with custom panel fabrication to optimize machine efficiency.

Every custom system undergoes rigorous in-house bench testing prior to delivery and site installation. We back every project with complete staff training to guarantee a smooth, trouble-free start-up and long-term operational reliability.

On-Site Services

Servicing industrial and marine hydraulic operations across Wisconsin, Illinois, Michigan, Ohio, and Minnesota, our certified field technicians bring expert fluid power solutions directly to your job site. We deliver comprehensive mobile support for heavy machinery and marine equipment.

Our field service team rapidly evaluates, troubleshoots, and performs on-site maintenance and emergency hydraulic repairs. By diagnosing issues at your facility, we restore equipment performance quickly and minimize costly operational downtime.

Retrofit Services

Avoid full equipment replacement costs by upgrading outdated hydraulic systems with pre-engineered retrofit packages. GT Hydraulics restores legacy machinery where replacement parts no longer exist, integrating modern fluid power components into your existing mechanical footprint.

Whether proactively upgrading modern machinery or modernizing obsolete systems to prevent unexpected downtime, our custom retrofit solutions enhance system performance, introduce digital controls, and significantly extend equipment lifespan.

Preventative
Maintenance Packages

Take control of your facility operations and eliminate sudden equipment shutdowns with a scheduled hydraulic preventative maintenance program. GT Hydraulics builds proactive service schedules tailored to your specific fluid power machinery and operating environment.

Backed by 24/7 emergency response, our maintenance capabilities include oil analysis, fluid sampling, cylinder repairs, custom machining, welding, and full component servicing designed to catch minor issues before they cause costly production disruptions.

Troubleshooting
& Repairs

When unexpected hydraulic failure threatens your productivity, GT Hydraulics diagnostic specialists quickly isolate the root cause. Utilizing advanced testing equipment, we troubleshoot complex electro-hydraulic systems to restore optimal operational performance.

From worn seals and fluid leaks to failing actuators, pumps, valves, or connection lines, most hydraulic failures stem from easily serviceable components rather than complete system collapse. We deliver fast, targeted repairs that get your equipment safely back online.
