Overall length is not usable deck length. A published side-rail width does not establish the unobstructed support width. Values above come from documentation, never from measuring the artwork.
Capacity with its conditions
Structural ratings do not approve axle loads, the tractor connection, route clearance or a permit.
What to verify
- The 80,000 lb uniform rating is not the 50,000 lb concentrated rating.
- Confirm the transport lock position and axle count on the actual trailer.
- Loading method
- Sliding axle / tilting deck
- Axle arrangement
- Two-axle reference; three-axle option needs build sheet
Manufacturer configuration detail
- Loading and tipping angles
- 7° loading angle and 15° dump angle in the manufacturer performance table; verify the operating configuration.Manufacturer source ↗
- Axle movement
- Hydraulic running-gear movement and a tilting main deck provide the loading path to the upper deck.Manufacturer source ↗
- Winch
- 20,000 lb published winch rating; confirm the pull and rigging conditions.Manufacturer source ↗
Documentary statements retain their original conditions. Only unambiguous numeric fields enter dimensional checks.
