This model simulate basic movements during Work in port. It includes rotation of upper tower on huge bearing, Which is driven by two pinions.
-
Large-sized bearing. (Axial, roller)
-
Crown gear.
-
Two driving pinions.
-
Electric motor with a four-speed gearbox
-
Hydraulic control.
-
Ejecting of rollers using hydraulic fluid.
-
Subsequent boom extensions.
-
The entire device is tilted.

Tilting of the crane's boom
The movable counterweight
-
Mounted to the main tower and beam type, which is mounted on the main beam.
-
When the boom tilt, the counterweight moves upward.
-
Ensures constant crane capacity.
-
Weights 22.5 tons.

This is my final work at technical secondary school in 2013. The goal was creating complete moveable crane. I was able to create model by using SolidWorks. As my pattern, I chose dockside gantry crane located in port of Decin upon river Elbe. I cooperated with local manager, who provided drawings for me.
The whole final work lasted over 3 months. It helped me to develop my skills in SW modeling, rendering and creating animations.
After completion of the final work I had to present it before graduation committee and I was successful.
Also with this final work, I competed at the national round of Students` Professional Activities in Brno. It was my first opportunity to present myself and my work to a jury and an audience.
Description
-
Gantry crane with a jointed booms.
-
Used for loading lump materials.
-
Highly movable.
-
High lifting speeds and driving.
-
Large operational range with short handling times.
-
Travels on rails.
-
The upper construction is rotatable by 360 degrees.
-
Joint construction mounted with a movable counterweight.
-
Due to the movement of the counterweight is a constant load capacity.
-
For tilting of the boom uses hydraulic mechanism.
Comparison of reality and the model.
Rocker Mechanism
The telescopic mechanism
-
The rockers spread the weight evenly on all casters.
-
Able to carry up to several dozents tonnes.
-
Better stability and the contact surface.
-
The steel construction must be able to carry tens of tons.
-
One massive steel welded box beam.
-
Equipped with a joint (deflection, dilatation).
-
High rigidity.
-
Heavier construction = large load on embankment
Construction of the portal
-
Placed on top of the rotary construction.
-
Adequate view of the service area, overlooking the ship.
-
Control of drive, rotation, tilting the boom and coiling the rope.
