An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge.
The American Society of Mechanical Engineers ( ASME) is an American professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via " continuing education, training and professional development, codes and standards, research, conferences and ...
The generally accepted definition of a crane is a machine for lifting and moving heavy objects by means of ropes or cables suspended from a movable arm. As such, a lifting machine that does not use cables, or else provides only vertical and not horizontal movement, cannot strictly be called a 'crane'. Types of crane-like lifting machine include:
The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life. Working Load Limit(WLL) is the maximum working load designed by the manufacturer. This load represents a forcethat is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor(SF).
