The Ultimate Proof
Theoretical engineering calculations must eventually meet physical reality. Load testing is the definitive validation that a crane, lifting beam, or structural point can safely bear the loads it was designed for.
We supply calibrated test weights, water weights, and tension dynamometers to perform highly controlled proof, static, and dynamic load testing. Whether commissioning a new overhead crane, returning a repaired mobile crane to service, or certifying a bespoke lifting attachment, our tests provide absolute certainty and ironclad compliance.

Testing Capabilities
Precision loading methods to validate structural and mechanical integrity.
Proof Load Testing
Applying loads exceeding safe working limits to verify structural integrity and safety factors.
Static Load Testing
Applying a stationary load to test deflection, braking systems, and structural rigidity.
Dynamic Load Testing
Testing through the full range of motion with a load to simulate worst-case operational stresses.
Anchor Point Testing
Pull testing of fall arrest systems and lifting lugs to verify concrete or structural adhesion.
Lifting Gear Testing
Testing of spreader beams, lifting beams, and custom below-the-hook attachments.
Hoist & Winch Testing
Verification of braking torque and clutch slip limits under maximum load conditions.
Why It Matters
The dangers of untested lifting equipment.
Brake Failure
Without dynamic testing at full load, hoist brakes may slip under real-world conditions, dropping the load unexpectedly.
Defective Manufacturing
Theoretical calculations cannot account for poor welding or material flaws; only a physical proof load can reveal these defects.
Uncertified Attachments
Using un-tested custom lifting beams is a direct violation of WHS laws, exposing PCBUs to extreme liability.
Our Process
Test Plan Engineering
Engineers calculate the required proof load (usually 110% - 125% of SWL depending on standards) and plan the methodology.
Setup & Rigging
Careful rigging of certified test weights, water bags, or load cells to the asset.
Controlled Loading
Incremental loading while monitoring structural deflection and mechanical response.
Post-Test Inspection & Cert
NDT of critical joints after testing to ensure no micro-cracking occurred, followed by certificate issuance.
