Different cranes have different goals. Of course, each crane has its own requirements for operation and maintenance. While some can move on the road, others must be assembled on site. One of the most commonly used cranes today is the crawler crane. Understanding the operation of crawler crane is very important for large construction work with heavy lifting.
The basic structure of mini crawler crane is that they consist of a standard cabin mounted on a crawler engine chassis. The chassis uses rails instead of wheels to work on the terrain at the construction site. In addition, the top deck rotates 360 degrees and has a box or lattice boom with extension options.
At the end of the boom there is also a wire rope with hooks, gripper or other attachments.
Unlike other cranes, crawlers don't use jibs because of stability reasons. Booms are lighter than other boom cranes, so crawler cranes have a larger working radius due to lower boom weights. However, a crawler crane cannot move from one location to another due to its size.
They often need to be assembled on site and may need additional cranes to be dismantled. Fortunately, renting a crane saves time and costs for shipping and maintenance.
The lattice boom is lighter than the others, but still offers an excellent crane lift. Crawler cranes can lift more than 600 tons. They are effective for large construction projects. Likewise, because of its size, this machine mainly acts as a permanent elevator in a closed workspace.
