ENTRO INDUSTRIES NEWS

April, 2025

Precision Engineering. Proven Innovation. Practical Results.

At Entro Industries, innovation is not a buzzword—it’s a design philosophy grounded in rigorous engineering, real-world application, and decades of field-proven results. From mobilizing multi-million-pound structures to retrofitting legacy systems for modern operations, our team is known for solving complex mechanical challenges with precision, creativity, and durability. Whether it's walking systems, pipe handling, or custom transport solutions, Entro delivers equipment that performs under pressure—because it’s engineered to do so from the start.

Below are recent highlights from our ongoing commitment to providing value-driven, technically sound solutions for the world’s most demanding environments.

Retrofit Solutions Save Clients Significant Costs

Entro successfully delivered retrofit packages to Patterson UTI, repurposing existing Entro walkers from unused rigs to newer fleet rigs. This strategic adaptation resulted in substantial cost savings while extending the lifecycle of existing assets.

Replacing Failed X-Y Sprinter Walkers

After experiencing multiple component failures—and lacking OEM support—A major Entro client contracted Entro to engineer a refurbishment of an existing system. Our solution retained the existing jacks and structure while replacing the failed control system, travel cylinders, and stomper feet shift mechanism. During the project it was then found that even the original jacks had failed, and had to be replaced.

HSI Walker Rehabilitation Project Underway

Entro is currently executing a full rehabilitation of a failed HSI walker, including jack reconstruction and replacement of steering drive components, steering linkage, and roller assemblies—bringing the unit back to reliable operational status.

Next-Gen Walking System Delivered for a New Client

Flex 5 in the shop

Entro recently delivered a 3.6 million lb. capacity X-Swing Pony Sub walking system a new client’s latest rig build program. The nine-month project involved collaborative design integration into client sub boxes and full operational testing at Entro’s facility prior to shipment—setting a new standard for walking system capability and integration.

BELT Feeder Transport System Eliminates Crane Requirements

Entro designed and built a 200,000 lb. BELT Feeder Transport System that allows apron feeders to be mobilized during operation—completely removing the need for crane lifts and significantly reducing operational costs and downtime.

Company background

As an experienced mechanical and structural engineer by trade, Harlan Smith founded Entro Industries in 1994. Having an extensive background in various industries, Harlan recognized a growing need for specific, simple solutions to complex mobilization problems. Since then, Entro has designed 250 moving rigs and built 200 of them. We’ve also been designing solutions to meet the needs of a variety of companies in a wide array of industries, including oil and gas, construction and aerospace.

SOLUTIONS FOR HEAVY HAUL AND STRUCTURE MOBILITY

Entro Industries designs custom solutions to large structure and specialty equipment moving projects around the world. We specialize in everything from heavy haul rolling gear and walking feet to custom hydraulics and control units. Our services are widely used in the oil and gas industry but can be applied to other situations in which a heavy load or large structure needs to be moved a short distance quickly, safely, and efficiently.

INDUSTRIAL ON- AND OFF-ROAD WHEELED TRANSPORT

Each Entro design has its own advantages. Whether you are skidding, rolling, or walking a rig, we have specially-designed solutions for any project. We design heavy haul jeeps, trailers, and custom suspension to meet the requirements of any rig move. For smaller applications, our Hitchwheeler allows for large structure or heavy loads to be moved without requiring the use of large, expensive machinery. All of our custom-designed heavy haul rolling gear is adaptable to both on- and off-road applications, making it versatile and mobile in any environment around the world.

WALKING OIL RIG SKIDDING SYSTEMS

Our custom engineered walking systems are among the most sophisticated in the industry. For example, with our X-Swing walking system, we were able to engineer a more compact and agile walking foot with double the speed of previous walking systems without sacrificing total load capacity. As with all our King Pin walking systems, the feet do not rotate but still maintain 360-degree mobility, making structures less expensive and more versatile. All of our walking feet and hydraulic systems aim to be as adaptable as possible and can be custom engineered to fit special project requirements.

PIPE HANDLING SYSTEMS

We also design custom pipe handling equipment for the oil and gas industry. Our specialty is mainly lift and infeed designs, but have plenty of experience in designing custom, automated systems for moving drilling tubulars in special circumstances, or for specific applications. These designs also carry our goal of enhancing the efficiency of an operation while keeping the crew safe.

OIL FIELD SERVICE AND SUPPORT

Beyond just the initial design and manufacturing of our products, we also provide field services and assistance for custom drilling rigs around the world. From engineering support and field welding/machining to project management and crew training, we are dedicated to providing the service to ensure the long-term functionality of all of our equipment.

If your drilling rig, heavy haul, or specialty moving project would benefit from our 55 years of experience in custom hydraulic and heavy haul solutions, call our offices at (503) 356.8888 or email us at info@entro-eng.com.
