美国采购需求：山猫、破碎锤、凯斯、卡特彼勒、斗山

I am interested in obtaining a quote for a hydraulic hammer that would be compatible with my 4-ton mini excavator. It's essential that the hammer works seamlessly with a quick coupler designed for easy attachment. I'm looking for information on various models available, including their specifications, pricing, and any additional features that may be beneficial for my projects. Could you also provide details on lead times for delivery, warranty information, and potential bulk order discounts? Understanding the overall value and reliability of the products available will help me make an informed decision. I'd greatly appreciate a prompt response so I can move forward with my procurement process. Looking forward to your reply!
