I'm looking to source a heavy dozer with specific dimensions of around 8m x 4.5m x 4m and a total weight of approximately 49 tons. This equipment is intended for transport from Shanghai to Hawaii. Could you please provide me with pricing, availability, and any relevant shipping details? Additionally, any information about product specifications and lead times would be greatly appreciated. Thank you!
