Step deck with loading system
Compare ramp contact width, traction and the lowest attachment clearance through the transition.
Can the tyres and articulation fit the loading path?
Wheel loaders
Measure the machine with the transport attachment fitted and its articulation secured in the required position. Tyre size changes both height and contact geometry.
Define the transported assembly
Keep tyre width, bucket width and the articulated machine’s transported length separate. The bucket may project beyond the tyre envelope, while articulation and oscillation affect the loading procedure. Record whether forks, a coupler, counterweights or protective equipment remain installed.
Lowbed
Check whether the lower loaded height is needed and whether the wheelbase and bucket can clear the chosen well and front-loading path.
Carry these details into the load plan
- Wheelbase and tyre contact widths
- Bucket/fork position and secured overall envelope
- Articulation restraint and transport instructions

Komatsu WA380-8: choose the actual bucket column
Komatsu’s dimensional sheet uses 23.5R25 L3 tyres and a ROPS/FOPS cab. It lists 2,780 mm over the tyres, while its bucket configurations list wider bucket envelopes. The sheet also separates standard and high-lift boom geometry and shows multiple bucket-dependent lengths. Do not combine the shortest length, narrowest width and lightest mass from different columns into one imagined machine. Keep the chosen tyre, boom and bucket configuration together.
- Identify the tyre, boom and bucket configuration
- Measure the bucket and complete stowed envelope
- Check articulation and the proposed loading path
- Obtain the actual machine weight and transport posture
Source checked 2026-11-07. This is an equipment-reference review, not a completed transport or a claim that a specific trailer fits. Measurements are not automatically imported into Highway Match.
Measure before selecting
- Outside tyre and bucket widths
- Wheelbase and axle weights
- Roof / exhaust transport height
- Bucket projection at stowed position
Loading approach
Compare ramp load limits and traction against axle reactions during the climb. The deck rating does not automatically establish the ramp rating.
Support & load concentration
Concentrated wheel loads need deck and crossmember verification. Record the actual tyre contact lines rather than treating the whole machine length as load distribution.
Configuration traps
A bucket may extend beyond the tyre envelope. Do not use width over tyres as the full transport width.
Build a measured configuration brief →Build the load record
Keep the model reference, actual attachment configuration, measured transport envelope and support drawing together. A change to the machine or its loading position requires the affected comparisons to be updated.
Equipment links support research. Highway Match uses the measurements you enter and does not silently import a related model’s values.
