Oversize load, and what that means for your shipment. At 29 ft 11 in wide this machine exceeds the 8 ft 6 in legal limit on every route. Your rate includes the right trailer, permits and escorts (likely two escorts), priced automatically, nothing added at pickup.

Before you book: what shippers ask

What trailer does a Caterpillar 797F need?

A multi-axle lowboy or RGN. At 21 ft 5 in tall the machine sits at 22 ft 11 in on an RGN deck and 26 ft 5 in on a flatbed; the legal loaded height is 13 ft 6 in in the US and 13 ft 7 in in Canada.

Does a Caterpillar 797F need oversize permits?

Yes. 29 ft 11 in of travel width exceeds the 8 ft 6 in legal limit; the quote prices permits for every state or province crossed, escorts likely two escorts, and files them for the carrier.

Can a Caterpillar 797F be loaded without a crane?

Yes when it starts and drives: it loads under its own power on the trailer's ramps. If it is inoperable, toggle starts-and-drives off in the form; winch loading is priced in, never added at pickup.

How should I prepare a Caterpillar 797F for pickup?

Empty the bucket or bed, fold and secure loose parts, note fluid leaks, and confirm the dimensions against the machine as it sits: debris, unfolded attachments or missing counterweights change weight and price.

What does it cost to ship a Caterpillar 797F?

Distance and the trailer class drive the price once the dimensions are set. Enter pickup and drop-off below; the rate is free, bookable and locked for 30 days.
