Understanding FMCSA Guidelines for Light Equipment
The Federal Motor Carrier Safety Administration (FMCSA) outlines specific cargo securement rules under 49 CFR Part 393. For equipment under 10,000 lbs, the relevant sections are 393.128 and 393.130. These rules apply to compact machines like mini excavators, compact track loaders (CTLs), and tractor-loader-backhoes (TLBs) commonly transported on pintle trailers or goosenecks.
Unlike heavy equipment over 10,000 lbs, which requires four tie-downs and additional measures for accessory equipment, light machinery falls under simplified requirements. The FMCSA allows two tie-downs—one at the front and one at the rear—provided they prevent movement in all directions: forward, backward, and side-to-side.
Terminology note:
While the FMCSA does not explicitly mention booms or buckets in section 393.128, common interpretation and enforcement practices treat any articulating part as a potential hazard. Hydraulic shovels, backhoe booms, and roller articulations must be locked or restrained to prevent movement during transit—even if the base machine is under 10,000 lbs.
Section 393.130(b) states that accessory equipment must be “completely lowered and secured to the vehicle.” Though this section technically applies to equipment over 10,000 lbs, many enforcement officers apply the same logic to lighter machines. The goal is to prevent movement during transport or in the event of an accident.
DOT Enforcement Varies by Region and Officer
Operators often encounter inconsistent enforcement. Some DOT officers may overlook a boom left in its transport lock, while others may issue citations for failing to chain it down. The safest approach is to secure all moving parts, regardless of weight class.
A seasoned operator in Wisconsin noted that DOT officers rarely penalize for “too many” restraints. A neat, well-secured load is less likely to attract scrutiny. Conversely, a sloppy tie-down job—even if technically compliant—may invite inspection and uncover unrelated violations.
Best Practices for Securing Light Equipment
To avoid citations and ensure safety:
A Story from the Road
In Illinois, a contractor hauling a Case 590 backhoe was pulled over by a county DOT officer. The machine had four binders securing the corners and a chain on the hoe bucket—but none on the front bucket. The officer, familiar with the contractor’s yard, had waited for the opportunity to issue a citation. Though the load was otherwise compliant, the unsecured front bucket was deemed a violation. The officer later admitted it was a “gimmie,” reinforcing the idea that appearance and thoroughness matter.
Legal vs Practical Compliance
While FMCSA rules provide a framework, real-world enforcement often hinges on interpretation. Operators should aim for practical compliance that exceeds the minimum. In the event of an accident, any unsecured component may be deemed a contributing factor, regardless of weight class.
Recommendations:
Transporting equipment under 10,000 lbs may seem straightforward, but tie-down requirements demand attention to detail. Federal rules allow minimal restraint, but practical safety and enforcement realities call for more. By securing all articulating components and presenting a tidy load, operators reduce risk, avoid citations, and uphold professional standards. In the world of equipment hauling, it’s better to over-secure than to explain under-compliance on the side of the road.

Terminology note:
- Tie-Down: A chain, strap, or other device used to secure cargo to a vehicle.
- Binder: A tensioning device used to tighten chains or straps.
- Accessory Equipment: Components like booms, buckets, or arms that extend or articulate independently from the main chassis.

Best Practices for Securing Light Equipment
To avoid citations and ensure safety:
- Use two chains and binders rated for the equipment’s weight.
- Secure the front and rear of the machine to prevent movement in all directions.
- Lock or chain down booms, buckets, and arms—even if they have transport locks.
- Avoid relying solely on ratchet straps for primary restraint.
- Inspect tie-down points for wear and ensure anchor points are rated for the load.

Recommendations:
- Treat all moving parts as potential hazards.
- Chain down booms and buckets even if not explicitly required.
- Maintain a clean, organized tie-down layout to avoid scrutiny.
- Keep copies of FMCSA regulations in the cab for reference.
