What is the SideFinger Towline Conveyor?

 The SI System’s Lo-Tow SideFinger towline system is ideal for manufacturing, assembly, and warehouse applications that require wheel load capacities ranging between 5,000 and 10,000 lbs. The system is designed to meet the motion
requirements for the industry’s most common production applications including crawling, synchronized, a-synchronized
and speedy return methods. 
Whether your system requires powered or non-powered spurs, precision, or non-precision stops, the SideFinger towline is sure to provide you with the precision, up time, and the controlled movement your system requires.  

SI Systems Sidefinger Towline conveyor
The SideFinger in-floor towline uses a proprietary tow chain with vertical rivets and rollers that have a pusher extending horizontally away from the chain centerline. This sideways mounted pushing finger allows the cart’s towpin to be transferred positively from the mainline to a transfer loop and vice versa.

A companion SideFinger track combines high performance with reliability for years and decades of up time. 
SideFinger Towline Step-by-Step
The SideFinger towline conveyor has a wide array of cart configurations. It accommodates simple four-wheeled transport dollies, ergonomic carts with lift/lower capability and rotators, and dual cart systems for extended loads (like a chassis). 
Obstruction-Free Conveyance

A clogged-up cart track is the number one cause of structural damage for towline systems.

SI Systems integrates a proprietary TrackGap system that utilizes chain guards to help keep contaminants such as fasteners, wood, scraps, and other items from engaging with the conveyor’s in-floor chain. At the same time, a void area in the track allows contaminants to accumulate harmlessly while the active tow pins automatically levels it until all debris is cleaned out. This design mitigates contaminants and eliminates chain jamming allowing systems to run consistently without jamming, damage, and costly downtime.

Our in-floor system combined with the total system access design, provides easy, obstruction-free 360-degree access to all workstations and around carts for lineside operations, and reduces instances of trip hazards and other workplace injuries.

SideFinger Vs Lo-Tow Towline Conveyor
SideFinger Towline
  • 2.5 tons to 5 tons wheel load capacity.
  • Proprietary conveyor chain.
  • Primarily used in straight-line or linear path configurations:
    1. Straight Line
    2. L-shaped
    3. U-shaped
    4. Loops
    5. Transfers and mergers
    6. All linear paths are possible
  • SideFinger can be configured for multi-floor operations.
  • Has a low profile 8.56" wide and 3.63" tall track cross section requires only minimum excavation 6" deep trench for installation.
Lo-Tow Towline
  • 55 tons wheel load capacity.
  • High-strength, heat-treated conveyor chain.
  • Primarily used in 'loop' or 'round-trip' configurations:
    1. From simple ovals to complicated serpentine paths
    2. Single loop or with multi-loop paths connected by loop-to-loop transfers
    3. Multi-floor operations by negotiating both ramps and/or elevators
  • Lo-Tow is versatile and can accommodate most configurations.
  • The trench is 6" deep. Certain items are deeper such as the drive and idler boxes. Dimensions depend on the wheel path.
