I have a question regarding cranes. Please advise
Thread Content
I would like to ask everyone: with the 15T and 50T cranes we’re talking about, under what conditions can these cranes lift such heavy weights? How is the weight threshold for cranes determined? There’s another thing I don’t understand: for example, in the case of a 15T crane, does its own weight necessarily have to exceed 15T? After all, a crane is a type of lever that requires effort to operate, so its own weight must be greater than the weight it lifts, right? Please ask a professional to give an answer.
The lifting capacity when the boom is not extended and is at a 45-degree angle upward.
The lifting capacity of the crane is based on ideal conditions, with the support structures in place, the load properly distributed, and the boom not extended at a 90-degree angle to the vehicle body
There is no strict proportional relationship between the weight of a crane and the load it can lift; values vary depending on the manufacturer. For what are considered traditional car-based or crawler-type cranes, the crane’s own weight is generally greater than the load it can lift. Additionally, cranes have specifications regarding their lifting capacity; there are strict requirements as to what weight can be lifted at what radius and what length the boom should be. The rated lifting capacity and the range over which lifting can take place are usually quite limited. For example, with a 25-ton crane, if you want it to lift 25 tons, this can only be done within a very limited range
For example, if you want to lift an object weighing 15 tons, but your crane has a lifting capacity of only 15 tons, then it’s definitely not possible to lift that object. It is recommended that you search in the database for solutions
