Wolverine Crane & Service

What Wolverine Crane & Service does

Wolverine Crane & Service, Inc., founded in 1994 and headquartered in Grand Rapids, Michigan, designs, fabricates, installs, and services overhead crane systems, wire rope and chain hoists, jib and gantry cranes, and structural runway systems for industrial facilities. Its in-house engineering and fabrication capabilities support custom box girder cranes up to 150-foot spans and 200-ton capacities, alongside rolled beam cranes, walkways, cabs, and platforms. The product line is extended by accessories including radio remote controls, variable frequency drives, load limiters, load summing scales, warning devices, C-hooks, coil grabs, magnets, and vacuum lifters.

The business operates a turnkey model in which design, fabrication, installation, inspection, and maintenance are delivered by Wolverine personnel rather than subcontractors, with 24/7 emergency service fleets dispatched from four Michigan locations (Grand Rapids, Romulus/Detroit, Kalamazoo, Traverse City). Revenue is generated through one-time capital equipment sales, recurring service and maintenance contracts, parts transactions, and certified OSHA/MIOSHA inspections, supplemented by the Crane Logic Service Program — an inspection and documentation offering that produces electronic reports with photo and video deficiency capture.

The company is structured as an employee-owned enterprise following its December 2025 transition to an Employee Stock Ownership Plan (ESOP). Its primary served segments are industrial manufacturers and operators of existing crane infrastructure requiring modernization or ongoing maintenance, with disclosed specialized applications in beverage/brewing and renewable energy/wind power. Operations are entirely concentrated in Michigan, and the company holds $5 million in general liability insurance including completed-operations coverage as a contractual qualification for high-risk industrial work.
