Rated load 20t; while overload 27.7t
Time: June 5, 2019
Location: Ulaanbaatar City, Mongolia
Event: An LH-type electric double girder bridge crane with a rated load capacity of 20t is undergoing acceptance test.
The crane test began.
After successfully passing the no-load operation, the bridge crane statically loads the 20t steel plate hangings. After 10 minutes, the crane load moves back and forth and left and right. After strict testing by the test personnel, all aspects of the crane performed well and passed the tests smoothly.
In order to verify the performance of the bridge crane, the customer temporarily decided to increase the weight of the load for the destructive overload test.
The steel plate was slowly added to 24t, and the crane began to lift for static load test. Engineers and workers are hiding outside the factory, and they are far away from the gate, leaving only our engineers and testers to continue testing. 1 minute, 2 minutes, 3 minutes...10 minutes, the crane successfully completed the static load test. The hoist moves left and right, the crane moves forward and backward, and the crane successfully completes the 24t dynamic load test. Weihua crane successfully passed another test!
The trial is not over yet! Customer continue to increase weight!
24t, 25t, 26t... The weight of the hanging object finally stayed at 27.7t, and the crane started another challenge! The on-site personnel who had been hiding outside the factory slowly began to approach. Lifting and holding, everyone at the site is watching the state of the crane; the crane moves left and right, back and forth, and everyone's attention follows the test. In the end, Weihua lifted its expectations and succeeded in passing the challenge again!
The measurement of infrared instruments shows during the test, the degree of crown, side bends and other aspects of Weihua Crane have reached international standards. After the test, the entire system staff gave a thumbs up, and the manager said: OK! OK! Very Good!
