The two most common types of industrial cranes are overhead and gantry. An overhead crane has a movable bridge that commonly carries a movable trolley supporting the hoisting mechanism, traveling on an overhead fixed runway structure.
A gantry crane is similar to an overhead crane except that the bridge for carrying the trolley or trolleys is rigidly supported on two or more legs. It runs on fixed rails or other similar runway, usually on the ground. Safety standards and operating procedures for overhead and gantry cranes are grouped together because they all have similar traveling and hoisting characteristics.
This course will allow all employees operating cranes for manufacturing and general industry purposes to identify the requirements for inspection, operational testing, proper rigging, lifting procedures, and other safety practices and devices relevant to crane operation.
