Certified load tests for your cranes.

Kristian provides load testing services for new and modified overhead cranes & hoists.

What is load testing?

Load testing involves the literal testing of limits, where a crane is pushed beyond its rated capacity under controlled conditions to identify any flaws or breaking points. This process allows for necessary repairs to be carried out prior to putting the crane into or back into service.

When a new overhead crane is installed or any physical changes occur to the crane system, a series of weight assessment protocols are mandatory to ensure the safety of all workers and employees. Current Occupational Health and Safety/CSA regulations which apply to Alberta and Saskatchewan require a Load Test Certificate before the crane can be put into regular use.

Kristian's Crane & Hoist Load Test Procedure

Overhead cranes undergo testing at 125% of their rated safe working load capacity. For example, if a crane is rated for 5 tons, a load of 6.25 tons will be applied.

While bearing this additional weight, the bridge and runways are then measured using the appropriate equipment to determine if the amount of deflection in the steel falls within the safe parameters outlined in the original engineered design.

Next, the crane undergoes testing to ensure that all of its functions are operating correctly. This comprehensive check includes hoisting, lowering, trolley travel, bridge travel, limit switches, as well as locking and safety devices, all of which are examined under the increased stress.

This testing process also enables the technician to assess and confirm that the load limit switches are set to their proper and safe settings.

Should the overhead crane and its components fulfill all the qualifications of the load test, our crane technicians will complete and sign off on a Certificate of Load Test off, which details all the checks and tests completed during the testing. A finalized Certificate of Load Test allows the new or modified crane to be put into service.
