Heavy Equipment Repairs
Downtime is costly. From cranes and forklifts to hydraulic attachments, we provide mechanical repairs that keep your heavy equipment productive and ready for work.
Heavy Equipment Diagnostics and Repair in Grand Rapids, MI
Construction, logistics, and industrial operations rely on specialized machinery to get the job done. Our heavy equipment repairs focus on the mechanical systems that power your most demanding machines, whether they lift, haul, or dig.
We service a wide range of equipment, including:
- Cranes (mobile, truck-mounted, rough terrain)
- Hi-los/forklifts (diesel, propane, electric—chassis only)
- Hydraulic attachments (grapples, augers, breakers, buckets)
Our technicians are trained to diagnose and repair core mechanical systems like:
- Engine performance and fault codes
- Hydraulic system leaks or pressure loss
- Worn cylinders, hoses, and seals
- Steering and suspension components
- Brake and driveline systems
Whether your crane is losing lift pressure, your forklift’s mast is binding, or your attachment isn’t operating at full strength, we’ll get it back in service with precision repairs and commercial-grade parts.
Chassis, Powertrain, and Hydraulic System Expertise
Heavy equipment failures can often trace back to foundational systems like engines, powertrains, or hydraulics. We evaluate and repair fuel injection problems, cooling system issues, transmission slippage, and any symptoms that compromise uptime.
For hydraulic-powered attachments, we test pump output, inspect flow control valves, and reseal cylinders to restore full function. On forklifts and similar machines, we address steering slack, brake wear, U-joint play, and stability concerns.
Our team also services undercarriage wear, damaged lift components, or chassis alignment issues that result from long-term field use. Whether it’s a machine with thousands of hours or a newer unit with OEM system faults, we have the tools and training to get you back on track without costly delays.

What Causes Hydraulic Attachments to Lose Power?
Low fluid levels, leaking seals, worn pumps, or clogged filters can reduce hydraulic pressure, leading to slow or incomplete movement. A full system inspection can help isolate the failure point.
Are Crane Repairs Different From Other Heavy Equipment?
Yes. Cranes often include additional components such as boom cylinders, outriggers, load sensors, and rotational gearboxes. These require specialized diagnostics and mechanical understanding.
