Due to the weight and volume, Sea Freight is the most economical option. For single units, Less than Container Load (LCL) using a wooden crate is common, but for multiple units, a 20ft or 40ft Flat Rack container or Roll-on/Roll-off (RoRo) shipping is safer to prevent structural damage. Always clarify the Incoterms; CIF (Cost, Insurance, and Freight) is convenient, but FOB (Free On Board) allows you more control over the shipping costs and the selection of a specialized heavy-machinery forwarder.
