In general, a double girder is occasionally used to gain additional headroom, whose capacity is over 20t, the owner usually use it to avoid loss of lifting height to handle the heavier loads. For top running systems capacity less than 20t, it is sensible to use a single girder design. Therefore, single girder and double girder design are used in different situations. We need to choose the suitable one according to actual working condition.

Manual powered cranes are very cost effective, but they are limited in certain small loading capacities. 3-phase electrical is always chosen for overhead crane systems because it is also an effective cost option. Single phase system can be used to lift goods up to 2 tons.
