Special notes

All information above are based on best available information, some variations may exist. All above info assume level loads and are subject to change.

* maximum gross capacity of the equipment may exceed lifting capacity of 92,000#. In those cases, Payload plus Tare must be below 92,000#.

* All loads, especially containers 40' or over must have the weight evenly distributed over the entire length of the container.

All must not exceed legal road limits when moved over public roads. Costs incurred due to overloading is to the account of the cargo. The weights provided above defined as:

  • Payload - Maximum; cargo weight the container is designed to carry
  • Gross - Maximum;cargo or payload weight plus the tare weight of the container.
  • Highway Maximum; cargo weight allowed by Washington State while moving in standard tandem axle configuration over the road with weight evenly spread.

* The list above illustrates the most common equipment types in our fleet, variations do exist.
