The Sentinel System

Pin-flange.
Two pins per joint.

Every Sentinel section uses the same pin-flange connection system with a double-head connector pin. Line up the flanges, drop two pins, and the joint is solid. Standard, Heavy Duty Crane and Back Lake sections all pin together.

  • ▸Two pins make a solid connection
  • ▸Pins designed to resist corrosion jamming
  • ▸Upper pin heads support a 2×4 flush with the deck
  • ▸One system across every model in the lineup

Questions

Frequently Asked Questions

Pricing, specs, lead times, and delivery — straight answers.

How much does a Sentinel sectional barge cost?
Pricing depends on the configuration — Standard 10×20 / 10×40 sections, Heavy Duty Crane 10×40×7, Back Lake 8×20, and any options (spuds, ramps, rakes, hoppers). Most contractors spec a fleet of multiple sections that lock together. Request a quote for current pricing.
What is the lead time on a new barge build?
Lead time depends on section count, options and the current shop schedule, and is confirmed in writing with your quote. We also keep a rotating in-stock inventory of new and used sections — see the Inventory page for what's listed now; availability is confirmed with your quote.
Can you customize a barge to my exact specifications?
Yes. Every barge ships with engineered and stamped drawings, and fully custom barges are built to your project requirements — non-standard dimensions, internal or external spuds, rake (angled bow) sections, drive-on/drive-off ramps, hopper boxes, kevels, lifting shackles, ladders, and railings. Send us your job specs and we will engineer the platform.
Do you ship barges to the USA and Canada?
Yes. We deliver throughout the United States and Canada. Sectional barges break down into truckable sections, and the Back Lake stacks two high on a truck and ships in Canada without permits. The barges are built in Cornwall, Ontario, and quoted in US dollars.
How much weight can a Sentinel barge hold?
The Standard Barge is rated for 36,000 lb evenly distributed deckload. The Heavy Duty Crane Barge supports a 58-ton payload per 41′4″ section with one foot of freeboard. The Back Lake Barge handles 20.3 tons per 20′ section.
What engineering documentation comes with a Sentinel barge?
Every Sentinel barge ships with engineered and stamped drawings. Steel conforms to CSA G40.20-13 / G40.21-13 grade 350W, welds are ¼″ fillet unless noted, and the design follows CSA S16-14.
How do the sections connect together?
Sentinel sectional barges use a pin-flange connection system with a double-head connector pin. Two pins make a solid connection, the pins resist corrosion jamming, and the upper pin heads support a 2×4 flush with the deck. Every model shares the same system.
