Overhead Crane Destructive Test in Mongolia

Rated load 20t; while overload 27.7t

Time: June 5, 2019

Location: Ulaanbaatar City, Mongolia

Event: An LH-type electric double girder overhead crane with a rated load capacity of 20t is undergoing acceptance test.

Moment: 14:30

The crane test began.

After successfully passing the no-load operation, the 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.

Moment: 14:55

In order to verify the performance of the 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!

Time: 15:15

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!

Dam Floodgate Gantry Hoist / Weihua Crane

The dam top floodgate gantry crane is mainly used for hydraulic equipment transport, installation and maintenance of hydroelectric generating units such as floodgates, trash rack etc.

Model MQ gantry crane can be divided into two kinds: unidirectional crane and bidirectional crane. The unidirectional hoist is fixed on the gantry frame. The Gantry runs along the track on the dam. And its service zone is a line, which can only be used to lift a gate of the same row, while the double direction gantry crane is with a trolley running perpendicular to the crane traveling. Thus, the double direction gantry crane can lift the floodgate or trash racks of different rows of upstream side and the downstream side.

dam top floodgate gantry crane

Features of Dam Floodgate Gantry Crane: 

1. Steel plate or box-type girder, electric driving motor of lifting mechanism, gear reducing hoist;

2. The operating mechanism of the crane is driven by the motor, and the closed operating room is mounted on the frame;

3. Running buffer device and windproof rail clamp are equipped under the gantry leg;

4. The spreader moves up and down along the gate slot or around the hinge of the gate;

5. The opening and closing of the gate in the movable water is related to the size of the load and the water hydrodynamic pressure;

6. For large span gate, it needs double lifting points and keep synchronization;

7. Large Lifting capacity, low speed, low work level, generally not more than 4 m / min, only for some quick gate, it can reach 10-14 m / min;

Dam crane hoist/crane can be mainly divided into two kinds according to their different structures.

1. Fixed type hoist: winding type, rack type, chain type, screw type and hydraulic type;

2. Mobile type hoist: gantry type, semi-gantry type, bridge and trolley type;
