Monkey crnae
A 2-story building can use a monkey crane to lift iron blocks
The user factory is a two-story building, with the first floor being the processing area and the second floor being the storage area for goods. The two-story building does not require the installation of elevators, so stairs are set up. However, it is not easy to move goods up and down by manpower, as it requires frequent trips.
It is entirely possible to use a monkey crane instead of manual handling. Power on, use remote control buttons to control up and down, with one operator on top and one operator below. Two people, one loading, are responsible for organizing the goods and hanging them on the crane hook. The other person can press the remote control on top to pull the goods up. The crane can rotate 360 degrees and stack the goods after being lowered.
Will the crane flip over during use? No, as long as we put two extension tubes on the base of the crane during lifting, press a counterweight on the tubes, and the counterweight ratio should be twice that of the heavy object. It should be noted that the goods cannot be overloaded and cannot exceed the actual lifting weight of the crane
