Optimizing Supply Chain Efficiency and Cable Installation on Semi-Trailers
Discover how a semi-trailer OEM reduced assembly failure rates and optimized supply chain efficiency using LAPP Tannehill's VMI and flexible SGX cable.
In heavy-duty manufacturing, small routing issues and manual procurement bottlenecks can lead to costly delays on the assembly line. When a leading Midwest manufacturer of specialized grain and dry bulk semi-trailers began experiencing installation failures and inventory congestion, they turned to LAPP Tannehill for a comprehensive solution.
Through a combination of material upgrades, local warehouse stocking, and an automated Vendor Managed Inventory (VMI) scanning system, the partnership successfully eliminated production bottlenecks while stabilizing supply chain operations.
Operational Challenges in Semi-Trailer Assembly
Producing custom aluminum trailers for the agricultural, construction, and energy sectors requires high-performance electrical cabling to power automated tarp systems and heavy equipment. However, the manufacturer encountered three distinct challenges that threatened production efficiency and profitability:
-
Material Limitations: The standard SGT cable previously used had a rigid jacket, making it extremely difficult for assembly workers to route through tight, curved trailer channels.
-
Compounding Assembly Failure Rates: Forcing stiff SGT cable into tight spaces risked slowing down line speeds and increasing assembly failure rates due to physical strain and handling difficulty.
-
Market & Supply Chain Volatility: Fluctuations in copper and raw material costs made long-term forecasting and price budgeting difficult, while manual inventory counts created risk of stockouts or over-ordering.
Strategic Solutions: Material Upgrades & Automated VMI
To resolve these pain points, LAPP Tannehill implemented a targeted program focused on product redesign and automated shop-floor replenishment.
1. Upgrading Material from SGT to Flexible SGX Cable
LAPP Tannehill recommended transitioning from rigid SGT cable to competitively priced, highly flexible SGX cable. The pliable construction of SGX cable allows technicians to easily route wiring through complex, curved frames—slashing installation times and eliminating assembly line failures.
"If they had continued to use the stiffer SGT cable or partnered with a distributor unable to manage volatile market shifts, they would have faced higher failure rates on the line and an increasingly difficult installation process for their assembly teams." — Betty Kirklin, District Sales Manager, LAPP Tannehill
2. Streamlining Replenishment with the Quick Pick Scanner
Rather than relying on manual counts or carrying excessive safety stock, the OEM implemented LAPP Tannehill's Quick Pick Scanner program. Shop-floor personnel scan items as they are consumed, providing instant digital tracking and automated inventory replenishment.
3. Strategic Warehousing & Space Optimization
To keep the plant floor clear for active manufacturing, LAPP Tannehill manages a rolling stock of SGX automotive cable out of a strategic distribution center in Savage, MN. Moving bulk inventory off-site drastically reduced the manufacturer’s footprint while maintaining continuous stock availability.
Traditional Procurement vs. LAPP Tannehill VMI Model
| Traditional Procurement Model | LAPP Tannehill VMI & Scanner Model | |
|---|---|---|
| Inventory Footprint | Heavy on-site storage; crowds the production floor. | Minimal floor footprint; rolling stock held in Savage, MN. |
| Tracking & Ordering | Manual counts, prone to unexpected stockouts or over-ordering. | Quick Pick Scanner: Instant digital tracking and seamless automated replenishment. |
Key Takeaways for Wire & Cable Supply Chain Management
Partnering with a specialized distributor offers distinct operational advantages over basic transactional purchasing:
Optimize Materials for Assembly Speed: Matching cable flexibility (such as SGX) to specific routing geometries prevents line delays and reduces component failures.
Reclaim Floor Space: Shifting bulk safety stock to local distributor warehouses frees up capital and physical plant space for production.
Automate Inventory Replenishment: Replacing paper logs with barcode scanners removes human error and prevents unexpected stockouts.
