Independent, third-party crane inspections across Connecticut
If you run cranes in Connecticut, you already know the pressure points: tight site access in places like Stamford and Bridgeport, heavy commercial work along the I-95 corridor, and schedules that do not leave room for surprise downtime. When your annual inspection is due, or you need a post-assembly, post-repair, or post-modification inspection, you need an independent inspector who shows up ready, documents everything cleanly, and helps you get back to work without confusion.
Marquis Crane Services provides third-party crane inspection and certification services throughout Connecticut for mobile and tower cranes, plus maritime and rigging inspections when your work crosses into port and waterfront environments. Coastal air and winter weather can be rough on wire rope, sheaves, pins, and structural components. Add in the stop-and-go pace of many Connecticut jobsites, and small issues can turn into big delays fast. We help you catch problems early, verify compliance, and keep your records organized for audits and customer requirements.
We have more than 35 years in the crane industry focused on repair, assembly and disassembly, and inspection. We use comprehensive inspection software to generate and email reports from the job site, and we maintain a cloud-based database so your paperwork is not scattered across trucks, trailers, and inboxes. That means fewer callbacks for “one more document” and less time lost chasing down past inspections.
Customers stick with us because we are thorough and easy to work with. As Chet Chludenski put it after a recent annual inspection, “Their team continues to exceed expectations year after year… extremely thorough… communication is always clear… it’s a relief knowing our equipment is in good hands.” That is the goal on every Connecticut site, whether you are managing a fleet in Hartford County or bringing in a large hydraulic crane with a luffing attachment for a complex pick.
