Grip engineers manufactures a range of cranes. Under slung cranes consist of bridge girder fitted to end trucks operating on the lower load carrying flange of the runway girder usually supported from the building roof trusses. "grip" made under slung cranes are available in single girder as well as double girder construction depending upon the load carrying capacity and the crane span. These are available in choices of hand operated as well as electrically operated crane motions. These cranes can also be called as transfer cranes as they can be used to transfer loads form one bay to another either directly from crane to crane or by fixed transfer sections. These cranes normally find applications where the load is to be transferred from one bay to another, as this type of load movement is not possible with the conventional top running eot cranes.
