The mobile crawler crane is particular crane designed with either a lattice boom or a telescopic boom. These move upon the crawlers tracks. Because this crane is self-propelled, it could move around certain work locations without the need for much set up. Due to their enormous size and weight, crawler cranes are rather costly and even hard to transport from one place to another. The crawler's tracks provide stability to the equipment and allow the crane to work without utilizing outriggers, however, there are several models which do use outriggers. Also, the tracks provide the machine's movement. Early Mobile Cranes Originally, the first mobile cranes were mounted to train cars and move along specifically made short rail lines. Once the 20th century arrived, the crawler tractor changed and this brought the introduction of crawler tracks to the construction business as well as the agricultural industry. Not long after, excavators adopted the crawler tracks and this further featured the versatility of the machine. It was not long after when crane companies decided that the crawler track market was a safe bet. The First Crawler Crane Northwest Engineering, a crane manufacturer in the USA, was the very first to mount its crane on crawler tracks in the nineteen twenties. 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 preferred means of traction for heavy crane operations. The Speedcrane The Moore Speedcrane, developed by Charles and Ray Moore of Chicago, Illinois was one of the first attempts to replicate the rails for cranes. Manufactured in Fort Wayne, Indiana, the Speedcrane was a wheel-mounted, steam-powered, fifteen ton crane. In the year 1925, a company known as Manitowoc Shipbuilding Co, from Manitowoc, Wisconsin recognized the tracked crane's potential and marketability. They decided to team up with the Moore brothers in order to manufacture it and go into business. The Crown RC 5500 Series was made on a vision that focuses on realistic difficulties in the workplace. This ground-breaking model features intelligent technology and best-in-class comfort and ergonomics. Keeping the operator comfortable and safe usually leads to more efficiency. 3-Wheel Stand-Up Counterbalanced Truck The company manufactures a 3-Wheel Stand-Up Counterbalanced Truck in capacities varying from 3000, 3500\three thousand five hundred and 4000 pound capacity. Performance Versatility The Crown RC 5500 excels in a busy work environment. This unit achieves greatness whether it is operating on the dock or in an aisle. It is designed to provide the operator unparalleled ride control, unmatched visibility and the best ergonomics. The exclusive FlexRide technology offered by Crown offers a suspended floorboard in order to eliminate a lot of the shock and vibration which operators must work with on a daily basis. Interestingly enough, a lot of the competitor's sit-down truck models could not match the reduced impact levels provided by the RC 5500 Series. Visibility - From a side-stance position in both directions of travel, this model provide maximum visibility for the operator. A low-profile provides a clear view mast as well a sculpted chassis allows the operators to be able to clearly see the fork tips, all around the truck and the fender. This optimum view enhances overall safety and lessens damage. Speed - Top travel speeds are among the best in the business and achieved through Access 1 2 3 Technology combined with the latest AC traction control. Performance levels are able to be custom tuned in order to match the application requirement or the operator's level of skill. Operator Safety & Comfort The suspended floorboard offered by Crown's FlexRide significantly enhances overall work performance by improving comfort and exhaustion is greatly lessened. The continuous vibration and shock can lead to extreme operator exhaustion for those exposed to those motions everyday particularly during travel over dock plates, expansion joints and rough grounds.
