Load test
WARNING: BVM spiders are load tested after manufacture or repair. Load testing is
mandatory on spiders which have not been load tested before. Load testing is required on
spiders which have been overloaded, for example jarring operations or operations that
have induced spiders to high accelerations or high impact loads. In addition, after the load
test, an annual inspection should be performed.
