Power Transmission Gearboxes

Ace World Companies has been designing and manufacturing power transmission gearboxes since 1987, when our first overhead crane rolled out the door with a gear reducer we built ourselves. We have never outsourced that work, and we never will. Every gearbox that leaves our facility is cut, fabricated, assembled, and tested under our own roof in Fort Worth, Texas.

That kind of vertical integration is rare, and it is the reason heavy industry trusts us with applications where failure is not an option.

In-House Gear Cutting, From Blank to Finished Drive

Our gear-cutting division is one of the largest of any American crane manufacturer. We hob, shape, grind, and heat-treat our own gears, then mate them to housings we fabricate on site. Because design, machining, and assembly all take place under one roof, our engineers can specify tooth geometry, lubrication paths, and bearing selection for the exact duty cycle a customer needs.

That tight feedback loop matters when you are building industrial gearboxes for Class E and Class F service, where ordinary catalog drives wear out long before the equipment around them does.

We are a longstanding member of the American Gear Manufacturers Association (AGMA), and our designs follow AGMA standards for rating, geometry, and quality.

Applications We Build For

Our crane gearboxes and material handling gearboxes power equipment in some of the most demanding environments in North America. Typical applications include:

• Wire rope hoists in steel mills, foundries, and shipyards
• Overhead and gantry crane travel, trolley, and bridge drives
• Wind turbines, including yaw and pitch drive replacements
• Drawbridges and movable infrastructure requiring high-torque, low-speed reduction
• Dam gate hoists and water-control machinery
• Transfer cars moving coils, slabs, and finished product across mill floors
• Special machinery for aerospace, defense, and military material handling
• Power rotating blocks and custom winches

If your application calls for power transmission components the catalog houses cannot quote, our engineering team can quote it. We have built one-off gear reducers for steel mills running 24/7 and matched-set drives for Cape Canaveral facilities lifting hundreds of tons.

Gearbox Replacement and Reverse Engineering

A failed drive on a critical line is expensive every hour it sits idle. We have built our gearbox replacement program around that reality. Send us a sample, a drawing, or even a worn-out unit, and our engineering team will reverse-engineer the geometry, upgrade the design where it makes sense, and build you a replacement that drops into the existing footprint.

This service covers Ace units, OEM units from other manufacturers, and legacy drives whose original supplier is long out of business. Because we manufacture more than 90% of our parts in-house, we control the schedule. No waiting on overseas castings or third-party gear shops.

Why Choose Ace for Industrial Power Transmission?

A few things set our approach to industrial power transmission apart from the catalog suppliers and the import resellers:

• American-made, from raw bar stock to finished assembly
• Custom-designed for each application rather than shoehorned from a catalog
• AGMA-rated geometry and quality standards
• Coordinated with the rest of your crane or machine, since we build those too
• Backed by a parts and service team that knows the product because we designed it

Whether you need a single replacement drive, a fleet of matched gear reducers for a new line, or a custom-engineered solution for an application that has never been built before, we would like to quote it.
