because of my involvement in heavy machinery, I have known the following machine needed to handle heavy stuff in manufacturing plant. the existence of this machine is needed to keep the process of transfering stuff to be efficient.
1. this one is called lifting magnete, it uses is to lift metal plate that is too heavy to lift by hand. just like the picture below.
2. this one is called chain sling, it is a chain needed in overhead crane.
3. this one is called boiler needed to generate power for the manufacturing plant.
4. and these two are forklift, it uses it to lift and transport stuff easily. many companies need forklift and you better know how to drive it so that you can get job easily.
