The mobile crawler crane is particular crane made with either a lattice boom or a telescopic boom. These move upon the crawlers tracks. Since this crane is self-propelled, it could move around certain work sites without the need for much set up. Due to their huge size and weight, crawler cranes are are hard to transport from one site to another and are fairly expensive. The crawler's tracks offer stability to the equipment and enable the crane to function without using outriggers, however, there are several units that do use outriggers. Also, the tracks provide the movement of the machine. Early Mobile Cranes Initially, the very first mobile cranes were mounted to train cars and move along specifically designed short rail lines. When the 20th century arrived, the crawler tractor changed and this brought the introduction of crawler tracks to the construction industry as well as the agricultural industry. Not long after, excavators adopted the crawler tracks and this further featured the versatility of the equipment. It was not long after before crane companies decided that the crawler track market was a safe bet. The Very First Crawler Crane Around the nineteen twenties, Northwest Engineering, a crane manufacturer in the USA, mounted its first crane on crawler tracks. It described the new machine as a "locomotive crane, independent of tracks and moveable under its own power." By the mid-1920s, crawler tracks had become the chosen means of traction for heavy crane operations. The Speedcrane Developed by Ray and Charles Moore of Chicago, Illinois; the Moore Speedcrane was one of the first to attempt to replicate rail lines for cranes. Made in Fort Wayne, Indiana, the Speedcrane was 15 ton, wheel-mounted, steam-powered crane. During the year 1925, a company referred to as Manitowoc Shipbuilding Co, from Manitowoc, Wisconsin recognized the tracked crane's marketability and potential. They decided to team up with the Moore brothers so as to manufacture it and go into business. Crown has made their RC 5500 Series to focus on the realistic difficulties faced in the workplace.
