Do Single-girder Bridge Cranes Require Factory Inspection?

Single beam suspension crane and CD1, MD1 electric hoist form a light and small track crane, which is commonly used in machinery manufacturing, assembly workshops, warehouses, etc.

The single-girder suspension crane is a medium-sized (A5) operating system with lifting capacities of 0.5 tons, 1 ton, 2 tons, 3 tons and 5 tons, and a span of 30 meters. The operating environment temperature is between 20-35 degrees, and the operating method is ground operation (wired and wireless).

Single-girder suspension cranes are not suitable for flammable and explosive media or high temperature, acid-base gas locations, nor are they suitable for hoisting molten metal, toxic substances and flammable substances.

When many users use this kind of monorail crane, they don't know whether to find the local special equipment inspection organization for inspection. All our export cranes will be inspected before leaving the factory.

Regulations: Cranes with a lifting capacity of 3 tons (including 3 tons) and a lifting height of more than 2 meters are special equipment. That is to say, cranes with a weight of less than 3 tons and a lifting height of less than 2 meters are no longer special equipment. Therefore, it is certain that lifting machinery under 3 tons no longer requires inspection and inspection by the local special equipment inspection organization.

If a customer is not satisfied with the inspection conducted by the special equipment testing organization. You can also submit a testing application to the local special inspection organization and entrust the special inspection organization to conduct the testing. The commissioned inspection process is basically the same as normal inspection.

Test lifting and monorail crane test lifting are important means to check whether the lifting equipment is qualified. When conducting equipment testing, the special equipment testing organization requires the supply of test hoisting objects of corresponding tonnage, and conducts a dynamic load test of 1.1 times the rated load and a static load test of 1.25 times the rated load of the lifting equipment. Therefore, it is necessary to test the lifting equipment after installation.

Statement: For lifting equipment below 3 tons, since there is no test report issued by the special equipment testing department, relevant qualification certification documents issued by the manufacturer or installation unit must be provided. On the one hand, it is a restriction on manufacturers and installation manufacturers, on the other hand, it is to borrow the professional technology of manufacturers and installation manufacturers to test equipment to provide guarantee for the safe use of lifting equipment.
