A480 pneumatic dimension stone strapping tool

The A480 is a pneumatic element stone strapping tool built for securing heavy dimension stone slabs and blocks during quarry handling, site fabrication, and containerised export. It generates 4.9 kN tensioning force at 0.6 MPa operating pressure and achieves seal tensile strength of 6.3 kN, figures that place it in the mid-duty range for pneumatic stone strapping equipment. The tool runs on compressed air rather than manual leverage or battery power, which removes fatigue limits on cycle counts in high-volume yards.

Standard industry practice for dimension stone strapping calls for polyester (PET) strap widths from 12 mm to 19 mm and thicknesses from 0.5 mm to 1.0 mm, though the A480 may accept a narrower band range depending on the feed throat and gripper geometry. Pneumatic tensioners of this class typically incorporate a wear-resistant steel gripper jaw, an air motor with rotary vane or piston drive, and a friction-seal or notch-seal joint mechanism. The 6.3 kN seal strength is adequate for stone packs up to approximately 2.5 tonnes per strap line, but buyers should cross-check this against their block weights and the number of strap lines per pack.

Quarry operators, stone fabrication workshops, and export packing stations are the core users of this equipment. The tool suits both flat-table strapping for polished slabs and rough-block lashing for granite or marble quarry output. Compressed-air infrastructure is prerequisite; buyers without onsite compressors must factor in a portable gas-powered compressor or a fixed plant line. No minimum order quantity, lead time, or incoterm is stated in the source data, so these terms must be confirmed directly with Shanghai Xin Nai Packing Machine Co., Ltd.

Shanghai Xin Nai Packing Machine Co., Ltd. is located at Room 501, Building One, No.655 Jiujing Road, Songjiang District, Shanghai 201615, China. The supplier carries a harbor trust tier and an imported supplier tier, both of which indicate a baseline marketplace presence rather than verified on-site audit status. The response rate is recorded at 0.00 percent with zero average response hours, which means no response data is available to assess communication reliability.

The listing presents the A480 pneumatic element stone strapping tool as the core product, with no additional machinery or tooling lines mentioned. No factory size, year of establishment, revenue, headcount, client references, or certification documents are stated in the source profile. Buyers should treat claims about ISO certification or other quality marks as unverified until documentation is requested and reviewed. The address places the company in Shanghai's Songjiang industrial zone, a district with established packaging and light-machinery manufacturing activity, but this geographic fact does not by itself confirm production capability.
