The main features of terrains are: its driving cab and crane cab combined, is evolved by the crawler crane (crawler), will track and walking part of the running gear bracket into the chassis has a tire to overcome disadvantage of crawler crane (crawler crane) track shoes on pavement damage, belonging to material handling machinery. Single girder gantry crane lifting equipment to do some work is characterized by intermittent exercise, namely a working cycle reclaimer, ship appropriate mechanism to transfer, unloading and other movements are working alternately, 

development and use of cranes on the market more widely. Gantry crane manufacturers  because they are not leg slings and hoists with often some accident, driving speeds are more cranes (crawler) fast; job stability, lifting large can be hoist walking within a specific range, but must ensure that road grading solid tire pressure to meet the requirements, hanging above the ground shall not exceed 50CM; ban with a load of walking long distances. To ensure the safety of operations, the current domestic basically prohibit the outriggers are not hoisting operations.
