  E.O.T Cranes – Single Girder or Double Girder
    These cranes move on the gantry rails fixed on top of the gantry girders. In this type 3 common motions are incorporated namely Hoist, Cross Traverse & Long Traverse. Sometimes according to the customers requirement auxiliary Hoist & Micro motions are also incorporated. Hoist & C.T. machineries are fitted on common frame called crab, which moves on rails fixed on the crane girders.
  Goliath Cranes
    Goliath or Gantry cranes differ from E.O.T cranes since they move on the rails fixed at ground level as compared to rails fixed at a height for E.O.T cranes. These are invariably used for outdoor duly as in stockyards and dam sites.
  Grabbing Cranes
    For handling bucket materials like fertilizers, chemicals, coal, lime-stone, gypsum, clinker, sand, ore, grains etc Grabbing cranes are used. The hoisting-cum-grabbing machinery of these cranes consists of two identical drivers controlled by a common controller.
  Bracket Cranes
    These cranes are mounted and run on a set of 3 parallel rails fixed on one side of the gantry structure. The crane girders overhang as Cantilevers over which the normal crab runs. These cranes are extensively used in machine shops and foundries besides, the normal E.O.T cranes, for handling smaller loads near the sides of the shop bay.
