Container has four castors at the bottom on which one can roll it comfortably under the cage blender frame. For heavy containers, one can use fork lift pallet truck to transfer the containers.
After bringing it under the frame, operate the hydraulic drive system which lifts the bottom platform and this bottom platform lifts the container along with its castor wheel and it raises the container till it gets locked with the top frame positively. This activates a sensor which than allows the blender to start.
After blending time is over the container stops exactly in a position where container is vertical position and then it could be lowered on it's four wheels.
