In wildfire management, few tools are as essential—and as potentially hazardous—as the drip torch. Drip torches are used to start controlled fires safely during prescribed burns to manage forest fuel loads and help prevent uncontrolled wildfires, however, even these essential tools can be improved. That’s exactly what our customer, Ricky Heflin, set out to do when he designed his adjustable torch system using our PA-01 Linear Actuator. In this article, we will cover highlights of how our PA-01 Linear Actuator was used to allow for a more efficient ignition system, better safety, and a more user-friendly solution for wildfire suppression.
The Story Behind the Project’s Inspiration
The project was inspired by firsthand experience when the original drip torch used by Ricky Heflin had a manual lever that was not convenient to operate, resulting in the device not being used as much as desired. When the torch holder was not used, operators would hold or operate the drip torch with their left hand while operating the 4 wheeler with their right hand. The drip torch during operation would rest against their leg and the side of the 4 wheeler, scaring the fender of the 4 wheeler. Ricky knew there had to be a better, safer way.
His solution was to create a system that would automate the torch tilt and lowering mechanism using a compact linear actuator for outdoor use. By doing so, he was able to achieve hands-free torch adjustments, freeing up the driver’s hands and improving the overall safety of the ignition process.
Selecting The Right Linear Actuator
Ricky began browsing for compact electric actuators online and came across Progressive Automations while doing a quick Google search. Several features stood out to him, including our offerings with:
- Dependable customer support
- Sealed actuators for harsh environments
- Solid 18-month warranty
- Customizable load capacity
- Stroke length variety
After contacting the Progressive Automations team with questions regarding application specifics and installation orientation, he made an online order for the PA-01 Linear Actuator for outdoor use. However, he soon realized he had selected the wrong load rating. He made a quick call to customer service, which resolved the issue with no hassle and reinforced his positive impression of our team’s responsiveness.
Using a rocker switch model RC-12 offered a pre-wired DPDT circuitry for straightforward control operation of the actuator’s extend and retract functions. The chosen PA-01-4-169-N-12VDC was the perfect fit as it offered Ricky the necessary specifications to handle the performance needs in an outdoor setting:
- 12 VDC operation
- Compact form factor
- IP65 ingress protection
- 169 lbs force rating
- 4 inch stroke length
- 0.30"/sec travel speed
Fabrication and Design Process
Ricky designed the entire adjustable torch system in SolidWorks, starting with a reverse-engineered CAD model of the existing torch holder. He then imported a 3D model of the PA-01 actuator (readily available under the 3D MODELS of our resources page) to build a compatible assembly. Once the design was finalized, he got in touch with his local steel supply company, Woodward Steel, to assist with water jet cutting and fabricating custom components from low carbon steel sheet.
With the steel pieces in hand, Ricky brought the project to life in his personal welding shop. The final setup allowed the drip torch to be lowered and tilted with precision using the PA-01 linear actuator, eliminating the need for manual handling during ignition.
The Primary Use and Application
The adjustable torch system is specifically designed for the ignition of prescribed burns, making it an invaluable tool in wildfire suppression practices. While debates exist around the long-term effects of prescribed burning—some argue that it contributes to forest fuel buildup—many agree that under the right conditions, it remains one of the most effective tools for protecting rural and forest-adjacent communities. Ricky shares that his system will not be used for a wide variety of duties, but will instead remain focused on prescribed burns where precise, hands-free ignition is essential.
Customer Testimonial
Throughout the process, Ricky’s experience with the Progressive Automations team, product integration, and website navigation was consistently positive. From pre-design questions to post-order adjustments, our team was responsive, friendly, and effective.
"The parts came quick. The actuator appears very well made. The rocker switch we purchased was just right for our application. We used the 3D CAD model to fit the actuator into our design. The unit fit and worked beautifully. We look forward to using it for a number of years." - Ricky Heflin
IN SUMMARY
By integrating our PA-01 linear actuator for outdoor use into a field-ready application, Ricky’s adjustable torch system improves the efficiency and safety of controlled burns—critical efforts that help prevent devastating wildfires from impacting rural and forest communities.
