These class A overhead cranes\u00a0are typically used for maintenance and\/or installation installation as well as handling materials at slow speeds. Class A overhead cranes have long periods of time between use.\r\n\r\nClass B overhead cranes are similar to Class A, only need to be durable enough to run at more frequent intervals.\r\n\r\nClass C overhead cranes are those that\u00a0<span style=\"line-height: 1.5em;\">are able to tackle loads that average 50 percent the rated capacity at a frequency of about 5 to 10 lifts at an average of 15 or so feet. <\/span>\r\n\r\n<span style=\"line-height: 1.5em;\">A tad more durable, Class D overhead cranes are for constant use lifting loads at about 50 percent of the overhead crane&#8217;s. These overhead cranes typically conduct 10 to 20 lifts per hour, again at 15 feet.\u00a0<\/span>\r\n\r\nClass E and Class F cranes are used for strenuous needs.\u00a0Overhead cranes that are\u00a0Class E and F include top-riding bridge cranes, gantry cranes, etc. To be deemed a Class F overhead crane, the crane needs to have the capacity to handle loads that are near to their own lifting capacity a majority of the time they are used.
