Permitted loads must be reduced to their lowest possible dimensions and weights.


Blades, buckets, counterweights, etc. may stay attached to main cargo as long as they do not exceed 16' wide.  Buckets, blades, counterweights, etc. may be hauled on the same trailer as main cargo as long as it is a part of the equipment being hauled.  If detached items cause load to be overweight, they must be removed and shipped as a separate load.

Superload Requirements

Loads or vehicles that are 17' wide x 17'6" high and 125,000 lbs. or more are considered Super-loads.  Loads that are permitted for length will be determined on a case by case basis as there is no set maximum.  This will depend on the actual length of the load, and the route being traveled.  Applications for loads over 200,000 lbs. must also include a Bill of lading, or an invoice showing proof of actual weight.  The State of Utah considers any load requiring bridge analysis and special routings to be a Super-load.  Diagrams of truck, trailer, and cargo configurations are required along with the proposed travel routes.

Super-load applications should be allowed up to four (4) days for processing and approval.
