We are looking for a magnetic system to unload 6m long bundles of metal tubing from a container (weight 600kg). Our initial thoughts were we could use a spreader bar on a crane with a magnet on each end.
This is probably the best product we carry for this application. You will require 1-3 units per load this will have to be tested to confirm because of the 5mm thickness pipes. we only have the 300kg Magnetic Pipe Lifter available (they have a 3.5 times safety factor).
