Trailer torsion springs can become a serious sourcing problem when incorrect parts, inconsistent quality, long lead times, or poor communication begin affecting trailer production. Purchasing professionals may know these components as trailer ramp springs, ramp assist springs, ramp door springs, lift gate springs, 180 springs, or even 6 x 6 springs. Regardless of the terminology, the sourcing problem is the same. Your company requires a manufacturer able to produce the spring correctly. The supplier must be consistent and provide necessary quantities to keep trailer production moving.
Ace Wire Spring & Form Co., Inc. manufactures custom trailer torsion springs for OEM applications from our Pittsburgh, Pennsylvania facility. If your company is developing a new trailer, Ace can review drawings and specifications. Or you may need another source for an existing spring, and Ace can review quantities and requirements. If issues arise with your current supplier, Ace will assess drawings and samples to determine the appropriate manufacturing path.
Trailer manufacturers rarely change an established supplier without a reason. Once a spring is approved and in production, purchasing teams prefer a dependable supply relationship. They avoid repeatedly sourcing the component.
Problems begin when that relationship stops working.
Long lead times can leave production waiting for components. Out of specification springs can create assembly problems. Incorrect shipments require purchasing and quality teams to spend time resolving issues instead of supporting production. Poor communication becomes especially frustrating when a delivery date is approaching and no one can provide a clear answer.
Ace has seen this sourcing problem firsthand. A trailer manufacturer that became an Ace customer endured repeated delays. It faced incorrect components and limited technical support from earlier spring suppliers. The company needed another source capable of producing its springs while also addressing engineering concerns that had developed around the existing design.
That is the type of opportunity Ace Wire Spring is built to evaluate.
Manufacturers use trailer torsion springs to provide rotational force and counterbalance assistance in trailer assemblies. One of their most recognizable applications is helping control heavy trailer ramps and doors.
As a ramp moves, the torsion spring stores and releases rotational energy. Properly designed spring assistance can reduce the force required to raise or lower the ramp while providing more controlled movement.
Technicians mount these springs around a shaft or incorporate them into a hinge-related assembly. The designer may require multiple springs or different configurations depending on the trailer design to achieve the necessary torque and movement.
Ace manufactures torsion springs to customer specifications rather than selling stocked retail replacement springs. Our focus is working with trailer manufacturers and other OEM customers that require custom components for production.
One of the most useful things Ace has learned from working directly with the trailer industry is that purchasing professionals do not always use engineering terminology when sourcing these components.
At the National Association of Trailer Manufacturers convention, Ace spoke directly with trailer manufacturers and purchasing professionals about how they search for these springs. Terms such as ramp assist springs, lift gate springs, 180 springs, ramp door springs, and 6 x 6 springs are all used within the industry.
That matters because the purchasing agent should not need to know that the component is technically a torsion spring before finding the right manufacturer.
If your company has an existing spring and needs another source, send Ace the drawing or sample. Please specify which trailer it is used on, provide the anticipated quantities, and include any specifications available. Our engineering and manufacturing teams can help determine what additional information is necessary.
When an established trailer torsion spring already performs correctly, the objective may not be to redesign it. Your company may simply need another manufacturer capable of producing the existing design consistently.
An engineering drawing is usually the best starting point. The drawing may communicate wire diameter, spring diameter, body length, leg geometry, material, direction of wind, tolerances, finish, torque requirements, and other information required for manufacturing.
When complete documentation is unavailable, Ace can also review physical samples and available application information. The amount of additional information required depends on the component and project.
Ace becomes relevant to engineers developing trailer systems and to purchasing teams who must find us another supplier this spring.
Trailer ramp springs are among the most common applications for large torsion springs within the trailer industry. Heavy ramps and doors can require significant force to move, making a properly designed counterbalance system important to both operation and equipment performance.
The spring must work within the geometry of the actual trailer assembly. Ramp weight, dimensions, available space, shaft size, required rotation, mounting arrangement, torque, and operating conditions can all influence the spring requirement.
These considerations are also why blindly substituting another spring based only on appearance can create problems. Two springs may look similar while producing different torque or behaving differently through the required range of motion.
For an OEM, the correct approach is to manufacture the spring around the approved engineering requirements of the trailer.
Poor manufacturing does not always cause premature spring problems. Design, installation, operating conditions, material selection, and spring deflection during operation all affect its service life.
The common trailer ramp spring failure points discussed within the trailer industry include excessive cycling and over deflection. Repeated operation of a torsion spring outside its intended range increases stress and reduces fatigue life.
This is one reason engineering information matters when establishing a new manufacturing source. Simply reproducing visible dimensions may not provide enough information to understand how the spring is expected to perform.
Ace’s spring design assistance can help customers review available requirements and identify manufacturing or design considerations when appropriate.
Sometimes changing suppliers reveals that the spring itself could be improved.
Ace’s trailer manufacturer case study provides a good example. After reviewing the customer’s drawings and samples, Ace’s engineering and sales teams worked directly with the trailer manufacturer’s engineer and identified concerns with the existing design. Recommendations were provided with the goals of improving manufacturability, reducing unnecessary cost, and supporting better long term performance.
This is an important distinction for OEM buyers.
A supplier can quote exactly what appears on a drawing. A manufacturing partner can also recognize when something deserves a conversation before thousands of components are produced.
Ace does not redesign customer products without reason or take final design responsibility away from the customer. Our role is to provide manufacturing and spring design experience that can help the customer’s engineering team make informed decisions.
Trailer applications can require larger spring geometries than many smaller industrial products.
Ace has invested specifically in expanded large diameter torsion spring manufacturing capabilities, and this capability has been a major part of our continued work within the trailer industry. The investment allows Ace to evaluate heavy duty torsion spring opportunities that fit the larger geometries and torque requirements found in ramp, door, gate, and related applications.
For trailer manufacturers, this provides another domestic source to consider when an existing supplier is creating production problems or when a new trailer program requires a custom torsion spring.
Not every project begins with an existing production spring. Trailer manufacturers developing new ramps, doors, gates, or other assemblies may need prototypes before releasing the final component for production.
Prototype trailer torsion springs allow engineers to evaluate torque, movement, leg position, fit, clearances, mounting conditions, and interaction with the surrounding assembly.
If changes are necessary, they can be evaluated before larger production quantities are ordered. Once the design has been approved, Ace can then evaluate the requirements for recurring manufacturing.
Keeping prototype development and production with the same spring manufacturer also preserves the manufacturing knowledge gained during development as the program moves forward.
Ace is a custom spring manufacturer, not a retail replacement spring distributor. We manufacture components around customer requirements, which means quantity is an important part of evaluating a project.
Trailer OEMs should provide realistic annual usage whenever possible. If your company expects to purchase 500 springs several times each year, that information is much more useful than requesting pricing for a small quantity without explaining the recurring production requirement.
Larger quantities can create opportunities for better piece pricing because material purchasing, machine setup, tooling, manufacturing preparation, and other costs can be distributed across more components.
For predictable requirements, blanket orders with scheduled releases may also allow a trailer manufacturer to purchase around annual usage while receiving springs according to its actual production schedule.
A competitive piece price is important, but purchasing professionals also understand the cost of poor supplier communication.
A low priced component does not provide much value if purchasing cannot get an order acknowledgment, engineering questions remain unanswered, or production discovers that a promised shipment is late.
Ace Wire Spring places significant emphasis on responsiveness because custom manufacturing requires communication between purchasing, engineering, quality, production, and the supplier.
When an issue or question arises, customers should know who to contact and receive a useful response.
For companies changing suppliers because communication has deteriorated elsewhere, that part of the relationship can be just as important as the spring itself.
Ace Wire Spring & Form Co., Inc. has manufactured custom springs and wire forms in Pittsburgh since 1939. Our company is family owned, U.S. based, ISO 9001:2015 certified, and focused on made to order springs and wire forms rather than stocked retail replacement components.
Ace has also made a deliberate commitment to the trailer market through our participation in the National Association of Trailer Manufacturers, direct conversations with trailer OEMs and purchasing teams, expanded large diameter torsion spring capabilities, and continued development of custom trailer spring programs.
Our goal is not simply to sell a trailer manufacturer one spring order. We want to become the manufacturing source that purchasing and engineering teams can rely on when they need custom trailer springs produced consistently over time.
If your company is having problems with its current spring supplier, you do not need to begin by learning spring engineering terminology.
Start with what you already have.
Provide Ace Wire Spring with the current drawing, physical sample, specifications, photographs, anticipated annual usage, typical release quantities, and information about the trailer application. If the existing design has performance or manufacturing problems, tell us about those as well.
Ace can review the project to determine whether it fits our manufacturing capabilities and identify what additional information may be needed.
