Lo-Tow Conveyor

Lo-Tow Towline Conveyor

Considered the “Industry Standard” since its inception over 60 years ago, SI’s Lo-Tow Towline Conveyor features the most efficient, effective, and reliable means for transporting heavy loads up to 55 tons through sequential assembly operations. Used primarily in “loop” type configurations, carts make repeating “round trip” cycles around the towline path. A fixed towline path is designed to route through your specific assembly operation. Diverts and merges can be designed to route carts between towline loops or for parallel processing.

Assembly carts attach to the Lo-Tow towline chain via a towpin. As the chain moves throughout the length of the towline path, the carts are towed along with it. Carts can be manually removed from the towline for offline processing by lifting the towpin out of the tow chain. Once any offline processing is complete, the operator can simply drop the towpin into the track slot to re-engage the cart back to the tow chain.

SI has completely revolutionized the towline industry, expediting production and assembly applications while eliminating error with the Lo-Tow Towline Conveyor’s jam resistant construction.

Safe and Ergonomic In-Floor Conveyance

Flush-Floor, Obstruction-Free Conveyance

  • Ergonomically designed towline system configured using a one-inch wide slot in the floor, allowing the cart’s towpin to engage with the in-floor towline chain
  • Eliminates trip hazards and other workplace injuries
  • Provides operators 360-degree access to the work, including access to the inside of the loop for lineside activities
  • Allows vehicle traffic to cross the towline path

Wide Array of Cart Configurations

  • Simple four-wheeled transport dollies
  • Dual cart systems for extended loads (like a chassis)
  • Mobile workstations with lift/lower capabilities and product rotators

Flexible Paths

  • Almost any path is possible: Simple ovals to a complicated serpentine paths
  • Single loop or with multi-loop paths connected by loop-to-loop transfers
  • Multi-floor operations by negotiating both ramps and/or elevators

What our clients are saying

“When we investigated our alternatives, we decided that the most important evaluation factors would be safety, quality, and productivity. SI scored highest in all three categories,” said plant manager, John Orth.
“Since installing the SI towline system, we’ve been able to cut our cycle times in half by systematically pacing the production and balancing workstation assignments. Not only has that greatly improved our productivity, but we now have much better control of the assembly process and a less fatigued workforce.”
