- after assembling the crane or
-
- after changes to location.
This applies to all Terex mobile cranes for the static and dynamic load test. A period of 5
minutes is sufficient for the static test.
The conditions listed above do not apply after reconfiguration or repairs to load-
bearing crane parts. In this case, the load test factor can be higher (in
accordance with e.g. the safety factors from the product standards). It is
recommended to involve the crane manufacturer in such tests.
Load Test Configurations
If a load test is required (due to national laws), the test conditions must correspond with the
conditions during the scheduled lift. It is acceptable for Terex to carry out a load test for a
given crane configuration with reduced loads (below the max. capacity), but at a greater
radius up to the maximum radius e.g. max. load moment.
Reason: In lattice mast cranes, erecting the boom from the ground is one of the most
critical load cases of a crane configuration with regard to load; erecting must therefore be
regarded as a load test for the tension-carrying structures such as the lattice mast sections
(with regard to pressure and bending stress), the bracing rods (tensile load), the boom
adjustment winch, the Superlift mast, etc.
