Light and small cranes "over-selection" lead to overburden

In the field of cranes, a lot of good strategies are not feasible. If you are preparing to determine the crane's lifting capacity, height and width, you may try to "much higher than I actually need, a little wider, and a little heavier." Oh, because the supplier of the crane system never knows my actual needs,
Or as time goes by, especially when the parts you are dealing with become heavier, chances are you will be deeply fond of how pre-emptive you were.
At the same time, however, it is very likely that the operator's push/pull force using the crane to assist the work becomes much larger than what is actually needed, they become very tired and the productivity is reduced. "More secure"? I think it is half the effort.

Choosing the right starting weight The following is an example of over-selection (compared by the crane's own weight):
The main beam has a length of 4.5m and a rigid beam crane with a weight of 500kg. Its own weight is 165kg.
The main beam has a length of 4.5m and a weight of 250kg. It is a rigid beam crane with a weight of 95kg.
The difference is 70kg
If you choose a larger main beam system, your operator needs to load a 70kg crane to push and pull the parts every day. It is important to remember that a brand crane is rated for the weight of the workpiece without the lifting structure. The weight of the hoist and the impact caused by the lifting are already counted, so please choose the weight wisely.
How to predict the size of the product in the future is very difficult, but the more critical and simple truth is to try to know the actual weight of the load and choose the right lifting weight for the crane.


Choosing the right length of the main beam. The above example shows that using the lifting weight higher than the actual demand will increase the weight of the main beam itself. This also applies to the selection of the main beam length of the crane. Self-weight comparison.
The high-boost rigid beam crane with a lifting weight of 250kg and a main beam length of 8.5m, the push-pull force required by the workers is 225kg
The high-bore aluminum system crane with a lifting weight of 250kg and a main beam length of 4.5m requires a push-pull force of 70kg for workers.
The difference is 155kg


Please select the appropriate length of the main beam without wasting according to the area of ​​the work area that you need to cover, so that you can effectively reduce the crane's own weight. In the above case, we reduced the length of the main beam and replaced the rigid beam structure with aluminum beams, so that the weight of the Gaobo crane was reduced by 1/3. If you want to operate this lifting system all day, which solution do you choose?


Choosing the right under-beam height When you install a new crane, you may want to keep the main beam as close as possible to the roof. However, although it looks more beautiful, the result is that the pulling force becomes very large. When the height of the crane increases, a pendulum effect occurs, and the operator is more laborious when pulling the parts along the main beam and the rail. Workers are too nervous, and they are easy to locate when working, and parts collide and damage occur. If possible, please try to ensure that the height of the beam of the Gaobo lifting system is within 3.7m. Whenever and wherever, the height below the beam exceeds 4.8m and is not ergonomic.
Choosing the right crane is like choosing a suit that fits. If the fit is just right, it will naturally add to your accompaniment; if it is too big, it will be unpleasant and unsafe.
