Quality & Compliance

Certified, tested and documented

A crane is a safety-critical machine. Our quality system is built to catch problems before they leave the factory — from incoming steel to final load testing — and to give you the certification and documentation your local approvals require.

Quality Control

Our six-stage QC process

Every crane passes through the same inspection gates, whatever its size.

Incoming steel plate stacked in the material bay awaiting inspection
Step 01

Incoming material inspection

Steel plate and components verified against mill certificates before use.

Crane girders being checked during fabrication on the shop floor
Step 02

In-process inspection

Weld quality, dimensions and camber checked at each fabrication stage.

Close inspection of steel wire rope construction and strand condition
Step 03

NDT of critical welds

Ultrasonic and magnetic-particle testing on load-bearing welds.

Crane wheel sets checked for alignment during assembly
Step 04

Assembly inspection

Mechanical fit, wheel alignment and electrical wiring verified.

Test load suspended from a lifting beam during a crane load test
Step 05

Load testing

Static (125%) and dynamic (110%) load tests on every crane.

Test reports and certificates being collated into the shipping file
Step 06

Final documentation

Test reports, certificates, drawings and manuals compiled for shipment.
