Optimizing Jack Performance: Proper Mounting Techniques and Dual Setup Configurations for Hydraulic Trailer Jacks

Proper mounting of hydraulic trailer jacks is vital for ensuring both safety and efficiency in various applications. Whether you're using jacks for trailer maintenance, industrial machinery, or other heavy-duty tasks, following best practices for mounting and setup can significantly enhance performance and safety.

This comprehensive guide covers how to mount hydraulic trailer jacks using mounting brackets, the benefits of dual setup positions, and welding tips for secure installation. 

Mounting Hydraulic Trailer Jacks: A Step-by-Step Guide

1. Choosing the Right Mounting Brackets

Selecting appropriate mounting brackets is the first step in ensuring a secure and stable installation:

  • Material and Strength: Ensure the brackets are constructed with heavy-duty steel and a cylinder capable of lifting 12K per jack, but that is the total lift from the front of the trailer.
  • Compatibility: Verify that the brackets are compatible with the specific type and size of hydraulic trailer jack you are using. Compatibility ensures that the jack will be securely held in place during operation.
  • Load Capacity: Check the load capacity of the brackets to ensure they can support the weight of the load. Overloading can cause bracket failure, leading to accidents and equipment damage.

At Primary Mover, we offer two main mounting styles in multiple different kit combinations. The two types of mounting configurations are the "Bolt On" and the "Weld On". The bolt-on version offers a 4-bolt pattern plate welded and powder-coated, ready to bolt to most modern trailers that have a manual style jack in a seamless swap. The second offers more customization as you can weld it on the trailer however you like.

2. Positioning the Jack

Proper positioning of the jack is essential for stability and safety:

  • Even Surface: Always position the jack on a flat, stable surface to prevent tipping or shifting. In our dual jack setups, they can jack a trailer even on unlevel ground with the addition of the flow divider valve that will balance the flow and divert the pressure to opposing jacks until they both reach the ground, then jack in unison.
  • Alignment: Align the jack with the load to ensure even distribution of weight. Misalignment can cause uneven lifting and potential damage to both the jack and the load.
  • Clearance: Ensure there is adequate clearance around the jack for safe operation and accessibility. This prevents any interference that could affect the lifting process.

3. Securing the Jack with Mounting Brackets

Follow these steps to secure the jack with mounting brackets:

  • Mark the Positions: Use a marker to outline the positions where the brackets will be mounted. Double-check the alignment and spacing before proceeding.
  • Drill Holes: Drill holes at the marked positions ensuring they are the correct size for the mounting hardware. According to the  National Institute for Occupational Safety and Health (NIOSH), precision in drilling helps maintain the structural integrity of the mounting surface.
  • Attach Brackets: Secure the brackets using appropriate bolts and nuts. Tighten the bolts evenly to ensure a secure fit. Uneven tightening can lead to stress points and potential failure.
  • Install the Jack: Place the hydraulic trailer jack into the mounting brackets and secure it according to the manufacturer’s instructions. Following the manufacturer's guidelines ensures that the installation meets all safety and performance specifications.

Benefits of Dual Setup Positions

Using dual setup positions can significantly enhance the versatility and efficiency of hydraulic trailer jacks. Here are some key benefits:

  1. Increased Stability and Lift Capacity: Not only are you gaining the ability to go from a 12K lift capacity to a 24K lift capacity, you also gain the stability of the wide stance of a dual setup, aiding in rock-solid stability. Our kits feature a flow diverter that can sense when one jack has made ground contact before the other in uneven ground scenarios and can divert pressure to the lagging leg to jack a trailer level on non-level surfaces.
  2. Enhanced Flexibility: Having multiple setup positions allows for greater flexibility in different applications. Whether you need to lift from various angles or heights, dual setup positions make it easier to adapt to different tasks.
  3. Improved Efficiency: Dual setup positions can streamline operations by reducing the need for repositioning the jack. This saves time and effort, making the workflow more efficient and reducing downtime.

Welding Tips for Secure Installation

Welding can provide a strong and secure method for mounting hydraulic trailer jacks, particularly in heavy-duty applications.

Here are some tips for effective welding:


  • Clean Surfaces: Ensure the surfaces to be welded are clean and free of rust, paint, or debris. The American Welding Society (AWS) emphasizes the importance of surface preparation for achieving strong welds.
  • Proper Fit: Make sure the parts fit together correctly before welding to avoid gaps or misalignment. Proper fitment ensures that the weld will be uniform and strong.

Welding Technique

  • Choose the Right Type of Weld: Select the appropriate welding technique (e.g., MIG, TIG, or stick welding) based on the materials and application. Different techniques offer various benefits depending on the requirements of the job.
  • Consistent Welds: Maintain a consistent speed and angle while welding to ensure even and strong welds. Consistency helps in creating a solid bond that can withstand stress and load.
  • Multiple Passes: For thicker materials, use multiple passes to achieve a secure bond. This approach ensures that the weld penetrates fully and provides maximum strength.

Safety Precautions

  • Protective Gear: Always wear appropriate protective gear, including welding gloves, a helmet, and flame-resistant clothing. Safety gear protects against burns, sparks, and harmful UV radiation.
  • Ventilation: Ensure proper ventilation in the welding area to avoid inhaling harmful fumes. According to OSHA, adequate ventilation is essential to prevent respiratory issues caused by welding fumes.
  • Fire Safety: Keep a fire extinguisher nearby and be mindful of flammable materials in the vicinity. Welding can produce sparks that may ignite surrounding materials, so having fire safety measures in place is crucial.

Ensuring Optimal Jack Performance and Safety

Properly mounting hydraulic trailer jacks and utilizing dual setup positions are crucial for achieving optimal performance and safety. By following the guidelines outlined in this blog, you can ensure that your jacks are securely installed and ready for any task. Always prioritize safety, use high-quality materials, and adhere to best practices for mounting and welding.

At Primary Mover, our jacks are equipped with dual counterbalance valves. These valves help to prevent jack drift when holding heavy loads and keep the jacks in the up position when traveling down the road. Lesser jacks could drift down while in transit, but our dual counterbalance valves ensure stability and safety during travel.

For more detailed instructions and visual guides, refer to the manufacturer’s manual or consult with a professional. By taking these steps, you can enhance the efficiency and reliability of your hydraulic trailer jacks, making your operations smoother and safer.
