Permitted Oversized & Wide Load Heavy Hauling Services
When freight exceeds legal highway dimensions—whether by weight, width, height, or overall length—navigating the logistics of interstate transit requires precision engineering, strict regulatory compliance, and state permitting expertise. JS Towing operates as a specialized direct-carrier heavy hauling service across Southern Wisconsin and Northern Illinois, delivering turnkey transportation for oversized, heavy, and wide-load cargo.
From wide-flange steel bridge girders moving down Interstate 94 to massive industrial processing tanks relocating through Kenosha, Racine, Rockford, and Greater Chicagoland, our heavy haul logistics team manages every detail from initial route surveys to final delivery.
Specialized Multi-Axle Oversized Equipment
We deploy high-capacity, heavy-duty trailer configurations engineered to distribute extreme weight and lower load center-of-gravity:
- Multi-Axle RGN & Lowboy Configurations: Designed for tall structural assemblies and ultra-heavy machinery exceeding standard 80,000-lb gross vehicle weight limits.
- Extendable & Stretch Flatbeds / Step-Decks: Accommodating extra-long steel beams, architectural trusses, wind turbine components, and industrial piping up to 80+ feet in length.
- Double-Drop & Well Trailers: Providing maximum vertical clearance under low highway overpasses for tall manufacturing vessels and electrical transformers.
- Steerable & Dolly-Equipped Transports: Allowing sharp cornering and precise maneuverability through tight city streets and construction job sites.
Turnkey Permitting & Route Survey Logistics
Oversized hauling requires meticulous coordination with state and municipal Departments of Transportation (DOT). JS Towing handles the entire regulatory workflow in-house:
- Comprehensive Route Surveys: We physically and digitally audit your planned route, measuring bridge underpass clearances, weight restrictions, utility overhead wires, and turning radii.
- State & Municipal Travel Permits: We acquire all required single-trip, multi-trip, or annual super-load permits across Wisconsin, Illinois, and interstate travel corridors.
- Certified Escort & Pilot Vehicles: We dispatch certified front and rear lead/chase pilot vehicles equipped with height poles, high-visibility flags, and direct radios to clear the road ahead.
- Police & Utility Coordination: For extreme super-loads, we coordinate municipal police escorts and utility bucket crews to temporarily raise low-hanging power and telecommunication lines.
Industries We Serve Daily
- Civil Infrastructure & Bridge Construction: Precast concrete girders, steel trusses, and heavy foundation equipment.
- Manufacturing & Industrial Processing: Large pressure vessels, industrial boilers, stamping presses, and factory assembly lines.
- Energy & Power Generation: Electrical substation transformers, generators, and wind/solar farm infrastructure.
- Agricultural & Forestry Bulk Processing: Oversized silos, grain dryers, and heavy logging processing units.
Frequently Asked Questions About Oversized Hauling
What constitutes an "oversized" or "wide" load in Wisconsin and Illinois?
Standard legal highway dimensions without permits are generally 8 feet 6 inches in width, 13 feet 6 inches in overall height, 53 feet in trailer length, and 80,000 lbs gross weight. Any shipment exceeding even one of these thresholds requires specialized oversize/overweight travel permits.
How long does it take to obtain state permits for wide-load transport?
Standard single-trip oversize permits across Wisconsin and Illinois typically take 24 to 72 hours to process. For super-loads exceeding 16 feet in width or 150,000 lbs in gross weight, engineering bridge reviews may require 1 to 2 weeks of advance lead time.
Are there specific time-of-day or holiday travel restrictions for wide loads?
Yes. Both Wisconsin and Illinois DOT enforce strict travel curfews for oversized loads. Transit is generally prohibited during nighttime hours, peak commuter rush hours (particularly in Greater Chicagoland and Milwaukee metro areas), and major national holiday weekends.
Can you provide crane rigging and heavy lifting services at loading and unloading?
While our drivers are experts in load securement, winching, and hydraulic trailer operations, we coordinate directly with your jobsite crane rigging crews to sync exact arrival windows for seamless top-loading and placement.
