Description

Stacker stability tester

This creation is about a stability testing machine, especially a stability testing machine for a stacker.

The stacker is a special handling device that installs the lifting mast at the front end of the car body. It can lift the cargo up and down, and carry the cargo before and after walking, and independently complete the loading and unloading work of the cargo, also known as the forklift or the forklift truck. The stacker needs to lift the cargo up. If the slope of the road exceeds the tolerance of the stacker, it may cause the vehicle to fall over. Therefore, all local governments have set up the stability check rules for the stacker. It can be sold or imported or exported by inspection.

Since the number of vehicles belonging to special tools is not as large as that of ordinary cars, the frequency of inspection is not very frequent. Most of the conventional inspection methods are carried out by the method of soil-based steelmaking. For example, placing the vehicles under test on a platform. Then use another stacker or crane to raise the side of the platform, tilt the vehicle under test according to the specified load block and measure whether the tilt angle meets the standard of sufficient stability to determine whether the test is qualified.

Because of the fact that the test bench and the lifting device are not strengthened and fixed, it is easy to cause the danger of sliding. In addition, each inspection needs to call a large crane to ensure that the large crane is hired in addition to increasing the cost, and also wastes waiting and erecting. Time, due to the weight of the stacker plus the weight of the uploading tens of metric tons, it is also easy to cause accidents.
