# Global Machine Trader — Shanghai Rongquan Machinery Co., Ltd. > Shanghai Rongquan Machinery Co., Ltd. (上海镕铨机械有限公司) is a construction machinery trading and export company based in Shanghai, China. Global Machine Trader is its machinery website. The business supplies used machinery and offers new-machine supply enquiries for available models. The product range includes excavators, bulldozers, wheel loaders and motor graders. Brand names identify the equipment offered; they do not establish manufacturer ownership or authorised-dealer status. Attachments can be requested, including buckets, breakers, grapples, quick couplers and augers. Compatibility depends on the machine configuration and the attachment's requirements. The website distinguishes model specifications, long-term supply or sourcing pages, and individual machine listings. Model specifications are references, not confirmation of an individual unit's configuration. New-machine and used-machine sourcing pages accept enquiries; their existence does not establish current stock. Individual machine details and availability require confirmation before purchase. Discontinued models may still have used-machine sourcing pages; these do not imply continued new-machine production. Condition labels have different meanings: OU is original used; RS is standard reconditioned, focused on mechanical preparation; RF is refurbished, with broader cosmetic and/or functional work; NEW identifies new-machine supply. The inspection record and agreed repair scope determine the condition of a particular unit. A displayed hour-meter reading is not automatically independently verified. Buyers can request machine photos, operating videos and inspection information before agreeing a purchase. Attachment selection, export documentation and transport planning form part of the quotation discussion. Container, flat-rack and breakbulk options depend on machine dimensions, weight, dismantling requirements and route. EXW, FOB, CIF and DDP enquiries are supported, subject to the agreed destination, service scope and written quotation. After-sales support and any warranty are defined in the transaction terms. Prices, quantities, production years, delivery dates and destination eligibility require current confirmation. Certification and emissions compliance are machine- and market-specific; this overview does not certify all equipment for every destination. Published model data and photographs alone do not establish inspection results, original hours or manufacturer warranty. For a quotation, provide the model or machine-page URL, preferred condition, quantity, destination, intended use and any year, hours, attachment or budget requirements.
