Continuing from: Mobile Crane Transportation To The Construction Site – Part 1
A mobile crane on a rough terrain carrier can travel on roads, but the low speed and the uncomfortable ride make the self powered transportation of the mobile crane inconvenient on long distances. For long distance transportation, the mobile crane needs to be carried by flat bed trailers. On the other hand, an all terrain crane can efficiently travel long distances on highways and other types of roads.
In order to move through bridges and other height obstacles on the roads, the all terrain crane may need some stripping down. The width and the height of the all terrain crane are no limitations for efficient transportation. Almost every all terrain mobile crane model comes with four wheel steering system which makes the crane maneuverable and capable to work in tight areas, and even in buildings or facilities if the floor can withstand the weight of the crane.
The crawler cranes are another category of mobile cranes that are heavily used on the construction sites. The crawler cranes are capable of moving around the job site easily, but for long distance transportation they need to be loaded on big trucks or to be transported by rail. Smaller crawler cranes can easily be loaded on flat bed trailers with the boom attached to the trailer for efficient transportation.
Larger crawler cranes need to be dismantled into smaller components and loaded into trailers for transportation. These machines are also transported by rail. When the crawler cranes are transported by rail, the carrier should be consulted because the weight and height limitations vary depending on the route. For the largest crawler cranes, like the Liebherr LR 13000, several flat bed trailers or rail cars are needed for transportation. The manufacturers of the crawler cranes are trying to design their machines to be easy for assembling. Some models are self-assembled and other are assembled in parts.
Most truck cranes can move on the roads with their own power. They are designed to be extremely flexible with only several components that need to be removed when moving from one location to another. The manufacturers of the truck cranes usually provide table with load adjustment data. The tables vary from manufacturer to manufacturer, but the general information is the same: the tables indicate which components of the truck cranes need to be removed when these machines need to be transported from one location to another. The data in the table needs to be respected in order to meet the height and weight transit regulations. The table also provides vital information about what needs to be done when the truck cranes move through ramps, bridges and floors.
