Portal Crane RTG Crane

Our crane are special equipments to remove, load and unload international standard containers. Running and moving in the yard, it has the advantage of high production efficiency and fine maneuverability, also the small sensibility to unevenness of the ground. RTG has tractor trolley and standard trolley two models. RTG is powered by cable drum. At the same time, diesel generating set is equipped for conditions when the power is off or the crane moves to another yard.
