Installation of a new (gem of a used) machine for our transload customer in Worcester. This JD machine replaces the same model previously in place, see process pictures. Originally designed for use on a skid steer, the original machine lasted 26 years and moved hundreds of thousands of pounds of material. We made the following modifications to the new machine prior to install: inspect and test all components, replace and reseal components as necessary, remove skid steer mounting plates, design fabricate and install hopper mounting plates and gusset, design fabricate and install operator platform with fall protection and removable aluminum section for service, relocate electric motor pump and hydraulic tank into box and replumb, paint.
