Changzhou Raymond Precision Machinery Co., Ltd.

Changzhou Raymond Precision Machinery Co., Ltd. is based in Changzhou, China and currently lists 13 active products. The catalogue focuses on hydraulic attachments for excavators, including earth auger units, vibro rippers and rock hammer variants. Each item falls under the HS‑84 machinery chapter, specifically the sub‑heading for earth‑moving equipment parts. The products are described using terms such as "hydraulic earth auger drill" and "hydraulic vibro ripper" which indicate they are intended for use on large construction excavators. The supplier’s top categories also reference hydraulic breaker spare parts and broader hydraulic equipments, confirming a specialization in heavy‑duty hydraulic components.

The listed products include the REA4500 earth auger for excavator, a mini‑excavator earth auger attachment, and several models of hydraulic vibro rippers for rock breaking. Additional entries cover high‑frequency vibro rippers, heavy equipment rippers and hydraulic rock hammers designed for navvy work. All items are described as used or new hydraulic tools, indicating they are intended for direct integration with excavator hydraulic systems. No HS codes are provided in the source data, so the description relies on the product names and their functional categories.

The catalogue presents a suite of hydraulic vibro rippers and earth‑auger attachments that are typical of Chinese‑manufactured construction accessories. In the industry, vibro rippers are usually rated for hydraulic pressures between 200 and 300 bar and flow rates of 20 - 40 L min‑¹, with steel housings that meet DIN 17230 strength criteria. Earth auger attachments commonly feature diameters from 200 mm to 600 mm, drill lengths up to 5 m, and are built to ISO 9001‑based quality management processes. Buyers often look for specifications such as maximum torque, vibration frequency (typically 20 - 30 Hz for vibro rippers) and wear‑resistant tip materials like carbide or alloy steel. The products listed align with these industry standards, offering the mechanical parameters expected for medium‑ to heavy‑duty excavator use.
