MJ Engineering collaborated with Focused Technologies to develop the award-winning (Best Maintenance of Way Product 2020) and patented SpikeEase railroad spike remover. The SpikeEase project originated as a college senior design project, which MJ Engineering completely redesigned to make stronger, lighter, more powerful, more ergonomic, and easier to use. This product utilizes a customized acme screw and acme nut that when turned by an off-the-shelf impact wrench uses leverage to pull the spike out of the tie. This product is an investment in safety and productivity that pays for itself by increasing production, reducing injuries, and eliminating the need for hydraulic equipment or claw bars. The SpikeEase is designed to be the lightest, easiest, and most eco-friendly spike remover in the world.

According to Focused Technology Solutions, the SpikeEase is the world’s most advanced battery-operated spike remover. Eliminating the need for hydraulic systems means un-tethering employees from service vehicles, heavy hoses, and expensive hydraulic power units.


  1. Design a battery-powered spike remover
  2. Improve maximum pull force
  3. Reduce the cost of and weight of the SpikeEase.
  4. Improve the ergonomics of using the SpikeEase in the field every day.
  5. Improve the strength and useful life of the SpikeEase


  • Weighs in at 30 pounds (not including drill or battery)
  • 3-7 seconds per spike removal
  • A rechargeable battery pack and a commercially available drill
  • Easy to transport anywhere the rail takes you
  • No hydraulic system to risk leaks and environmental hazards.

Custom Designed Robotic Cell for Adhesive Application within the Automotive & Appliance Industry

MJ Engineering custom designed and built a portable robotic cell for the automotive and appliance industries. This robotic cell is used for applying a single part epoxy to both automotive and appliance components. Based off a customer supplied 2D, Auto CAD print, we first created Solidworks 3D models of the cell, ensuring that the design met all of our client’s unique product requirements. We also designed the end of arm tooling (EOAT) which possessed built-in temperature control capabilities.

In addition, MJ Engineering also designed and built the epoxy delivery system, which included a number of unique components and features, such as a high-pressure main valve, flexible tubing, and a high-pressure rotary union and metering valve. The cell meets tight tolerances for placement of the adhesive. The cell size is 48-in wide, 48-in deep and 84-in high.

Once assured that our custom designed robotic cell fulfilled all of our customer’s precise product requirements, we then installed this unit in our client’s facility in Coshocton, Ohio. This robotic cell was ready to start up immediately after installation was complete. We also provided our client with comprehensive hard copy and electronic documentation for this unit.

This portable robotic cell contained multiple controlled heating zones for constant viscosity of epoxy delivery, consistent bead size from tray to tray, and changeable epoxy nozzles for specific applications. This cell also allowed for controlled bead of epoxy in tight tolerance patterns on stamped metal parts, providing a speed and consistency that is not capable with traditional manual procedures.

Our robotic cell additionally allowed for storage and easy retrieval of multiple programs, which helps eliminate set-up time for operators. Our automated robotic cell provided our clients higher quality products in reduced production time.

Finite Element Analysis of an Amusement Park Ride

MJ Engineering was retained by a ride manufacturer of an amusement park ride to make sure the ride met US standards for a Virginia-based amusement park. To demonstrate that the structure conformed to local, state and federal regulations, MJ Engineering performed a finite element analysis of the structure under dynamic and static loads. We also helped to establish or guide the design of a number of different control systems including speed and safety controls. To make sure the ride was installed properly, MJ Engineering provided guidance and analysis throughout the entire installation process. Using a variety of specifications (ASTM F2291, AISC 316, AISC M015, ANSI B11.TR3, ANSI B77.1, ASME B15.1, ANSI/AWS D1.1, D14.4, BS 5400-10, SAE T833, ASCE 7) we were able to see that each segment of the ride conformed to the required standards (ASTM, AISC, ANSI, ASME, AWS, BS, SAE, ASCE).

Machine Design of Custom Steel Pipe Handling System for the Manufacturing Industry

A manufacturing client approached MJ Engineering to design a custom steel pipe handling system. Using the latest in SolidWorks 3D CAD software, we were able to design both the needed machinery and a master control system.

The custom designed machinery is capable of loading and unloading raw pipe lengths into a CNC threading and cutting cell. We created a handling system that is able to cingulate stock pipe from an accumulation hopper, convey pipe from the output side and sense pipe length and sort it into the correct bin on the discharge end.

To make the machine even more user-friendly, MJ Engineering designed a master PLC system that not only controls movement of the pipe into and out of the CNC cell but also has a touch screen HMI that allows easy operator access and troubleshooting.

We supported the client by offering full assembly and installation of both the steel pipe handling system and the PLC.

Custom Designed Automated Vision Inspection and Data Logging System for the Automotive Manufacturing Industry

An automotive Tier 1 manufacturing client approached MJ Engineering to design and install a quality system for the purpose of logging data and images from assemblies to provide product traceability. The system uses a 2D reader to read the unique serial identifier and then record the associated assembly data.

One part of the assembly process requires installing screws to specified torque requirements, the next stage is an automated vision based part inspection that checks to make sure the system is assembled correctly. Both the torque data and the vision image are logged to permanent files.

If the torque reading does not fall within tolerance or the vision inspection testing fails the part is not allowed to be packaged and an alarm will sound if an attempt is made to package failed parts.

Project Description

This automated Quality system reads and logs; 2D datamatrix codes, torque values and vision inspection pass/fail criteria.

Capabilities Applied/Processes

Station Design

  • Create custom application software to preform logic and logging functions
  • Create SolidWorks 3D Models of Station Concept
