埃及采购需求：疏浚头、疏浚泵、船用绞车、甲板起重机、疏浚齿轮箱、疏浚管道

I'm reaching out to request a quotation for a cutting head designed for a specific model. The head should have a diameter of 2220mm. Please include details on the materials used, any customization options, and your lead times for production and delivery. Additionally, if you could provide information about any related products or services that might be useful in conjunction with this cutting head, that would be great. I'm particularly interested in pricing tiers based on quantity, as well as any available discounts for bulk orders. Looking forward to your prompt response!
