Marlin Steel Circular Floats - USA Patent Number 10,286,943 European Patent Application No. 19 170 823.9Jet engine maintenance, repair, and overhaul (MRO) is an essential process to keep aircraft engines and parts in prime condition so they can operate efficiently, effectively, and safely. Since most aerospace parts require flawless surface conditioning to operate, aerospace MRO can be a meticulous and time-consuming process.


However, the MRO process doesn’t have to be inefficient. Marlin Steel’s engineers have designed and patented custom aerospace circular floats to improve jet engine MRO operations. With Marlin Steel's patented circular floats (USA Patent Number 10,286,943, European Patent Application No. 19 170 823.9), you can transport jet engines, blades, and vanes smoothly and quickly without worry of damage.

Circular Floats Help Protect Jet Engines During Maintenance

There are a plethora of ways that our patented circular floats facilitate a more effective and safe MRO:

Protecting Jet Engine Turbine Blades

During the MRO process, jet engine turbine blades need to be moved throughout the maintenance facility. This can result in damage to the jet engines if they are not secure. Marin Steel’s patented circular floats ensure jet turbine protection in numerous ways.

Each circular float contains three adjustable ratchet straps to securely scrap products that would otherwise tip over. These ratchet straps are further protected by bumpers. Engines are also locked down with five hook carabiners to keep the product secure through its travel. Additionally, each float’s thick steel side walls protect jet parts from being hit on the side by objects or equipment when being transported.

Reducing Rework and Scratching

Marlin Steel's patented Circular floats ensure thorough jet turbine engine blade protection by prohibiting metal on metal contact. There are strict regulations on metal part contact; the FAA requires that jet turbine engine blades and vanes be sent out of commission for repair for even small damage. Our Circular floats prevent contact by using neoprene liners and other protective coatings. Each mobile float is coated to provide a safe cushion for the engine that will also prevent engines from being damaged during movement.

Additionally, the neoprene-lined rim further ensures no stretching of parts and a soft landing. Each circular float’s features an expanded metal base that allows potentially damaging debris, metal shavings, and fasteners to exit before they abrade the delicate turbine engine blade parts.

Other Benefits of Circular Floats

Our custom aerospace circular floats offer more than protection for aircraft parts. They also ensure safety for employees as well, and enable quick and effective MRO servicing.

Employee and Part Safety

Jet engine turbine blades are both delicate and very heavy. This can put strain on employee’s backs and can cause injury if parts are not secure. Our patented circular floats help mitigate this problem by facilitating smooth and easier transport for employees. Floats can support weights up to 600lbs, but the superior caster design allows east movement, with a 30lbs push and pull force max on employees’ backs. The straps and carabiners ensure each part is secure, so employees do not need to worry about heavy parts, such as a turbine fan blade, falling out.

The neoprene foam liner that trims the outer walls is not just for the safety of the aerospace parts, but also for employees. This soft foam envelopes the top of the sheet metal walls and throughout the bottom, protecting employee hands from harsh metal.

Ease of Transportation

Jet engine MRO can be a lengthy process when heavy and delicate parts need to be safely transported between operations. With circular floats, minutes can be shaved off of MRO processes, increasing overall efficiency. Gliding casters allow a smooth ride for up to 600lbs—which allows employees to move parts through the facility quickly. Additionally, circular floats are pallet jack and forklift friendly.

To make your MRO process even more efficient, circular floats can be outfitted with the “Marlin Pusher,” a custom aerospace handle that enables employees to move float through operations seamlessly. The handle can be adjusted for short and tall employees, making it even easier to operate.

Marlin Steel's Custom Aerospace Stainless Steel

Aerospace grade stainless steel can facilitate better parts cleaning than other aerospace metals, such as aluminum. Baskets and floats made of aerospace steel have strong corrosion resistance and a high temperature tolerance, so they can be continuously used for years
