TACKLERS Overhead Gantry Cranes, ideally used in various industries and projects by the customers. Heavy-duty Gantry / Goliath Cranes are Single Girder; manufacture double Girder Semi Gantry Crane and Portable Gantry in multiple styles with capacities ranging from 1 ton to 100 ton. Gantry Cranes or Goliath Cranes are very similar to a top running crane. The only difference is that the legs support the crane bridge, and the rails are at ground level. The additional leg structure makes the crane a more expensive option to choose. It is offset by the considerably cheaper low-level rails. The advantage increases with increased track length making them particularly suitable for large outdoor stockyards. A Semi-Goliath Crane / Semi-Gantry Crane is a hybrid of a goliath and a top running crane with one end of the bridge supported by a high-level gantry and the other by a leg running on a low-level track. Outdoor duty goliath cranes are checked for stability under storm conditions. Special storm anchors are provided to prevent the toppling of the crane under storm conditions.
