How to Ship a Trencher: Chain Trencher & Wheel Trencher Transport Guide

Trencher Weight and Dimension Ranges

Trenchers span an enormous range of sizes. Understanding where your machine falls determines the trailer type, permit requirements, and total shipping cost:

Trencher Class	Examples	Operating Weight	Transport Width	Transport Height
Walk-Behind / Mini	Ditch Witch C16X, Barreto 1324	500–2,000 lbs	2–3 ft	3–4 ft
Compact Ride-On	Ditch Witch RT45, Vermeer RTX250	5,000–15,000 lbs	5–6 ft	5–7 ft
Mid-Size Chain Trencher	Vermeer T655, Ditch Witch RT120	20,000–50,000 lbs	7–9 ft	8–11 ft
Large Chain Trencher	Vermeer T1255, Tesmec TRS 900	50,000–120,000 lbs	9–14 ft	10–14 ft

Note: Transport dimensions differ from operating dimensions. The chain boom/digging chain must be secured in the transport position, which typically reduces height but may increase length. Always confirm transport dimensions with the manufacturer's spec sheet before booking.

Trailer Selection by Trencher Size

Walk-Behind and Mini Trenchers (Under 5,000 lbs)

Small walk-behind trenchers can typically be transported on a standard flatbed or step deck trailer alongside other equipment. They're often shipped as part of a multi-unit load with other utility equipment. No oversize permits required if dimensions are within legal limits.

Compact Ride-On Trenchers (5,000–15,000 lbs)

Compact ride-on trenchers fit on a step deck trailer in most cases. The lower deck height (42 inches) provides adequate clearance for machines up to 9 ft tall. If the trencher is wider than 8'6", an oversize permit is required. These machines are typically self-propelled and can drive onto the trailer via ramps.

Mid-Size Chain Trenchers (20,000–50,000 lbs)

Mid-size chain trenchers require a lowboy or RGN trailer. The low deck height (18–24 inches) is essential for machines that are 8–11 ft tall in transport position. An RGN is preferred for tracked machines because the detachable gooseneck allows the machine to drive directly onto the trailer without ramps. Key considerations:

• Confirm the chain boom is fully retracted and secured in transport position
• Remove or fold any auxiliary attachments that increase width beyond 8'6"
• Verify that the machine's transport weight (including any attached chain) is within the trailer's rated capacity

Large Chain Trenchers (50,000–120,000 lbs)

Large chain trenchers like the Vermeer T1255 (operating weight ~120,000 lbs) are superload territory. These machines require:

• Multi-axle RGN or specialized lowboy with 7–20 axles depending on weight
• Route surveys to identify bridge weight restrictions and clearance issues
• Engineering review for loads over 150,000 lbs GVW
• Law enforcement escorts in most states
• Possible partial disassembly (removing the chain boom or cutting head) to reduce dimensions

Tie-Down Requirements for Trenchers

DOT regulations require that tie-down aggregate working load limit (WLL) equals at least 50% of the cargo weight. For a 40,000 lb trencher, you need tie-downs with a combined WLL of at least 20,000 lbs. Practical requirements:

• Minimum 4 tie-down points for equipment over 10,000 lbs — typically two forward and two rear
• Use Grade 70 transport chain (3/8" chain has ~6,600 lbs WLL; 1/2" chain has ~11,300 lbs WLL)
• Chain through designated tie-down points on the machine frame — never around hydraulic lines, cylinders, or the chain boom
• Block the tracks or wheels with wooden chocks to prevent fore-aft movement
• Secure the chain boom/digging chain with additional straps or chains to prevent movement during transit

Permit Thresholds for Trencher Transport

Federal and state permit thresholds that apply to trencher transport:

• Width over 8'6" (102 inches): Oversize permit required in every state
• Height over 13'6": Oversize permit required (some states allow 14 ft on certain highways)
• GVW over 80,000 lbs: Overweight permit required in every state
• Width over 12 ft: Pilot car (escort vehicle) required in most states
• Width over 14 ft: Front and rear escorts required in most states; some states require law enforcement
• GVW over 150,000 lbs: Superload classification — engineering review and route survey required

Loading and Unloading Considerations

Trenchers present specific loading challenges:

• Ground conditions: The loading area must be level and firm. Soft ground can cause tracked trenchers to sink during loading, making it difficult to drive onto the trailer.
• Chain boom position: The digging chain must be fully retracted and the boom secured before loading. Verify the boom lock is engaged.
• Hydraulic fluid: Check for leaks before loading — fluid on the trailer deck creates a slip hazard and may violate environmental regulations.
• Fuel level: Some states require fuel tanks to be less than half full for oversize loads. Confirm requirements for your route.
