Your Crane Deserves More Than Just Another Repair Shop
You’ve got a lift scheduled for Tuesday, a rigging crew on the clock, and a crane that won’t build hydraulic pressure or throw a fault code you’ve never seen before. Every hour that machine sits idle, you’re bleeding money and burning goodwill with the people counting on you. You don’t need a lot to store your equipment. You need a shop that understands what a crane actually does and gets it back to work fast.
At Flying Wrench Services, 31516 Commercial Ave NE, Kingston, WA 98346, we’ve been the go-to for crews who can’t afford excuses since 2002. As Heavy Equipment Specialists, we work on boom trucks, hydraulic cranes, and lift equipment the way we work on any diesel — with real diagnostics, honest answers, and no runaround. Whether it’s a National, an Altec, a Terex, or a Manitex mounted on your chassis, we know these machines carry your reputation as much as your payload.
Why Crane Owners in Kingston Choose Flying Wrench Services
We Speak Your Language, Not Mechanic Jargon
You know your equipment. You don’t need a lecture — you need a mechanic who’ll talk to you like a working partner. When you call us about a slow boom or a leaking outrigger cylinder, we listen first, then explain what we find in plain terms.
- A clear description of what’s actually wrong, not a parts guess
- Straight answers about what’s urgent versus what can wait
- Written estimates before we turn a wrench
- Updates while your machine is in the shop, not radio silence
If you’ve ever walked out of a shop feeling talked down to, that’s not us. We’d rather have a conversation over the fender than hand you a three-page invoice full of things you never asked about.
Crane Expertise Without Dealership Pricing
Manufacturer service centers for lift equipment are often weeks out and priced like it. We’re an independent diesel and heavy equipment shop, which means real expertise without the boutique markup.
- Diagnostic equipment including J-Pro and TEXA for engine and system faults
- Technicians who understand hydraulic systems, PTOs, and load-sensing controls
- Experience across the diesel engines that power crane chassis
- Fair labor rates priced for working crews, not corporate accounts
As Diesel Diagnostic Equipment users, we don’t just clear codes and hope. We find the root cause so the fault doesn’t come back on your next lift.
Transparency That Rebuilds Trust
Maybe the last shop told you it was one thing when it was another. We know that burn, and we work to earn back that trust one honest repair at a time.
- Written estimates you approve before work begins
- No upselling on parts you didn’t come in for
- We show you the worn or failed component when it makes sense
- Honest timelines — days, not weeks, wherever the job allows
We’re the most reviewed local diesel repair shop and the top-rated heavy-duty equipment repair shop in the area, and we didn’t get there by playing games with people’s livelihoods.

Model-Specific Crane Expertise
National Crane Service and Repair
National boom trucks are workhorses on utility and construction crews, and they show it. We address hydraulic drift, worn boom pads, and outrigger leaks along with the diesel carrier’s engine and drivetrain needs. Whether it’s a load chart display fault or a slow-building boom, we chase down the cause and get you rigging again.
Altec Crane Service and Repair
Altec digger derricks and cranes see heavy duty in utility fleets. Common concerns include hydraulic pump wear, rotation bearing play, and electrical faults in the controls. We diagnose the carrier’s diesel systems and the crane’s hydraulics as one connected machine, so nothing gets missed between the two.
Terex Crane Service and Repair
Terex boom trucks and cranes demand precise hydraulic and load-sensing performance. We handle cylinder seal failures, boom extension issues, and stabilizer problems, plus the diesel engine and cooling systems that keep the carrier moving. Downtime on a Terex costs real money, and we treat it that way.
Manitex Crane Service and Repair
Manitex boom trucks are common on Kitsap and Peninsula job sites. We service the PTO, hydraulic pumps, and winch systems alongside the diesel chassis engine, fuel system, and emissions equipment. When your Manitex starts feeling sluggish under load, we find whether it’s a hydraulic issue, an engine problem, or both.
Grove Crane Service and Repair
Grove cranes are built for serious lifting, and their hydraulic and control systems reward proper upkeep. We diagnose swing and boom control faults, address hydraulic leaks, and keep the diesel powertrain in tune. Our goal is simple — keep your Grove reliable so your crew never stands around waiting on a machine.
Common Issues Across Crane Models
Cranes across every brand tend to share the same failure points, and knowing where to look saves you time and money.
- Hydraulic Leaks and Drift: Worn cylinder seals and aging hoses cause boom drift and slow lifts — we pressure-test the system and replace failing components before they strand you mid-job.
- Outrigger and Stabilizer Failures: Leaking outrigger cylinders and worn pads compromise setup safety, so we inspect and rebuild them to restore solid footing.
- Diesel Power Loss Under Load: Fuel delivery, turbo, and emissions problems rob a carrier of the power it needs — we diagnose the real cause instead of throwing parts at it.
- Electrical and Control Faults: Load-sensing systems and control panels throw confusing codes; our diagnostic tools trace them to the actual wiring, sensor, or module at fault.
- Overheating on the Carrier: Radiator, water pump, and cooling failures shut a crane down fast, so we service the cooling system before summer heat becomes a problem.
- Emissions System Warnings: EGR and DPF faults trigger derates that cut power right when you need it — we clean, repair, or replace as needed to keep you running clean and legal.
