Crane Stability Testing

Truck-mounted crane configurations

A number of factors need to be considered when installing truck-mounted cranes. These factors include; the size of truck, location and size of outriggers, frame strength/suitability, and other mechanical features. These factors can alter the final stability of the truck mounted crane.

Crane Stability tests

By physically load testing the specific truck-mounted crane configuration, we can accurately determine the extents of the cranes stability. Depending on the stability result, the factory load information may be invalid. If the crane is deemed unstable, we can calculate a new safer load chart, to reduce the danger of tipping.

Kova Engineering is the leader in the crane stability testing in British Columbia. Our personnel have extensive experience of performing stability tests on a variety of cranes.

We will work with you to ensure your truck-mounted crane configuration meets the BC occupational health and safety regulations. Specific load charts will be created to match your truck and crane combination. We can perform stability tests on your truck-mounted unit in the following, but not limited to:

  • 180° And 360° operation
  • Full Outrigger Extension
  • Mid Outrigger Extension
  • Outriggers Fully Retracted
  • Custom Outrigger Configuration (Multiple Outrigger Extensions)

Kova Engineering has set the standard for Stability Test Load Charts. We take pride on providing our clients with clear and concise charts that are matched specifically to their truck and crane combination.


It is mandatory that all truck-mounted cranes must be tested for stability. Crane stability tests in BC, must comply with occupational health and safety regulation:


14.2(5) (a) and (c). (CSA Z-150-98, ASME B30.22, SAE J765)
