How to Ship a Large Excavator (30–50 Ton Class): Complete Transport Guide

Dimensions and Weight: 30–50 Ton Excavator Class

Specifications vary by manufacturer and model, but typical transport dimensions for 30–50 ton excavators fall in these ranges:

Specification	Typical Range (30–50 Ton Class)	Example Models
Operating Weight	66,000–120,000 lbs	Cat 336 (~82,000 lbs), Komatsu PC360 (~79,000 lbs), Hitachi ZX350 (~77,000 lbs)
Transport Length	32–42 feet	Boom retracted, bucket tucked
Transport Width	10–13 feet	Track width; may exceed 8.5 ft legal limit
Transport Height	10–13 feet	Cab roof to ground; varies by boom position

Note: These are transport configuration dimensions with the boom retracted and the house rotated to face forward. Always measure the actual machine — manufacturer specs are for reference only and may not reflect field modifications, attachments, or wear.

Trailer Requirements

A 30–50 ton excavator requires a multi-axle RGN (Removable Gooseneck) trailer. Standard configurations:

• 3-axle RGN: Suitable for excavators up to approximately 42,000 lbs payload (lighter 30-ton class machines). Legal GVW with a standard tractor is approximately 80,000 lbs total.
• 4-axle RGN: Handles excavators in the 42,000–65,000 lb payload range. Adds one additional trailer axle to distribute weight and comply with bridge formula requirements.
• 5-axle RGN: Required for excavators in the 65,000–80,000 lb payload range. Common for Cat 336, Komatsu PC360, and similar machines.
• 6-axle or 7-axle RGN: Required for the heaviest 50-ton class machines (80,000+ lbs payload). These configurations require overweight permits in most states.

The RGN's removable gooseneck is critical for these machines — it allows the excavator to be driven onto the trailer under its own power, eliminating the need for a crane at the origin. The gooseneck detaches hydraulically, the trailer drops to ground level, and the excavator drives on at low speed in the lowest gear setting.

Transport Configuration: Boom and Bucket Positioning

Proper boom and bucket positioning is critical for both legal compliance and safe transport:

1. Rotate the house: Rotate the upper structure so it faces forward (toward the cab). This positions the counterweight over the rear of the trailer for better weight distribution.
2. Retract the boom and stick: Fully retract the stick (arm) and position the boom at its lowest legal height. The goal is to minimize total load height.
3. Tuck the bucket: Curl the bucket fully and position it as close to the machine as possible. If the bucket adds significant height or width, consider removing it and shipping it separately on a flatbed.
4. Lower the boom to the trailer deck: If the trailer has a boom rest or cradle, use it. The boom should be as low as possible to minimize total load height.
5. Engage the travel lock: Most large excavators have a travel lock that prevents the upper structure from rotating during transport. Engage it before the machine is secured.

Securement Requirements

Per DOT cargo securement regulations (49 CFR Part 393, Subpart I), large excavators require a minimum of four chains for securement, with additional chains required as weight increases. Standard securement for a 30–50 ton excavator:

• Two Grade 70 or Grade 80 chains at the front of the machine (at manufacturer-designated tie-down points near the front idlers or track frames)
• Two chains at the rear of the machine (at the rear idlers or track frames)
• Additional chains at the boom/stick if the boom is not resting on a cradle
• Chains must be tensioned with binders and checked after the first 50 miles of travel

Straps are not appropriate for machines over 10,000 lbs. Chains must be rated for the load — use Grade 70 (transport chain) or Grade 80 (alloy chain) with working load limits appropriate for the machine's weight.

Permit Requirements

A 30–50 ton excavator will trigger oversize and overweight permits in virtually every state. Typical permit triggers:

• Width: Track width of 10–13 feet exceeds the 8.5-foot legal limit — oversize permit required in every state
• Weight: Operating weight of 66,000–120,000 lbs exceeds the 80,000-lb GVW limit — overweight permit required for heavier machines
• Pilot cars: Loads over 12 feet wide typically require one pilot car; loads over 14–16 feet wide (varies by state) require front and rear escorts

Cost Factors

Shipping a 30–50 ton excavator costs more than smaller equipment due to the specialized trailer, multi-state permits, and potential pilot car requirements. Key cost drivers:

• Distance (per-mile rate, typically $3.50–$7.00/mile for this class)
• Number of axles on the trailer (more axles = higher trailer cost)
• Number of states crossed (permit cost per state, typically $50–$300 per state)
• Pilot car requirements (typically $1.50–$3.00/mile per pilot car)
• Non-running surcharge if the machine cannot be driven onto the trailer
