Gantry Cranes

Portal & Semi-Portal Gantry Cranes


Street has more than 70 years experience designing and manufacturing Portal or Goliath/semi- Goliath cranes and is considered a leader in the field. These gantry cranes and are essentially overhead cranes on legs which run on floor mounted rails. Semi-Portal cranes have a single leg and floor rails at one end of the crane bridge with a high level rail at the other. The rail-less semi-portal crane with polyurethane tyre wheels running directly on the floor is a Street specialty. Larger Portal cranes are more normally used outdoors in applications such as stockyards and shipyards but Street manufactures many smaller Portal and semi-portal cranes for indoor use. All our gantry cranes can be equipped with Street ZX wire rope hoists VX open winch hoists or LX chain hoists.
