Crawler Crane Safety in Material Handling| 6 Crawler Crane • The main advantage of the crawler crane is the ability to move and lift items and other heavy loads around the construction site very easily. Some have telescopic arms that enable them to change size—a plus because they are adaptable to various terrains. It has many disadvantages and advantages depending on its use. Analysis of overhead crane accidents reveals three common safety hazards that every company using overhead lift systems should be aware of to keep their workers safe. Crawler crane moves it self with the help of tracks which is also called crawlers. Therefore, machinery with this type of wheel is most commonly used in hilly areas where slope is more and center of gravity is low. A crawler crane has its boom mounted on an undercarriage fitted with a set of crawler tracks that provide both stability and mobility. A crane that isn’t tracking properly also causes extensive wear to the wheels, wheel bearings, and wheel flanges—as well as premature wear to the motor drives and other equipment. Explain the advantages and disadvantages of each type of mobile crane as to how it is used in the construction industry. • the biggest disadvantage of the crawler crane is the big size and weight. CRANE BUCKLING OR COLLAPSING – The crawler cranes have weight limits to ensure they do not tip over. Hydraulic Advantages - ease of travel - quick mobilization - extendable outriggers/rough terrain. Built on an undercarriage fitted with steel tracks rather than wheels, a crawler crane can be used on soft ground without sinking. It walks on tracked devices. If the maximum weight is exceeded the crane will be in danger of either buckling or the boom may collapse.
