Shelling Manipulators

The Mayo EeZee-2010 manipulator is a purpose built Shelling Robot, designed with simplicity in mind, to work around the clock, at minimum cost. In most automatic shelling applications, it’s not necessary to have what we would call “An all-singing, all-dancing robot” when a simpler manipulator will do the job just as well, and just as efficiently. 3 standard versions are available, with custom sizes also available built to order. The standard weight range of the 3 models is: Mayo EeZee-2010 Model 150 Up to 150kg Payload Capacity, Mayo EeZee-2010 Model 250 – Up to 250kg Payload Capacity, Mayo EeZee-2010 Model 500 – Up to 500kg Payload Capacity.
