Yt28 jack hammer

The YT28 is a high-efficiency air-leg rock drill. You must verify the cylinder diameter (80mm) and stroke length (60mm) to ensure standard impact energy. Ensure the air consumption is approximately ≤81 L/s at 0.5MPa to match your existing air compressor capacity. Additionally, check for integrated water-injection systems for dust suppression, which is critical for underground mining safety.

Prioritize suppliers using high-grade alloy steel for the piston and internal valves, as these parts endure high-frequency impact. The shank size should be standard (Hex 22x108mm) to ensure compatibility with global drill steel supplies. Ask for heat treatment certifications for the impact parts to guarantee a longer service life and resistance to fatigue failure.

For international trade, ensure the product carries the CE mark for European markets or meets MA (Mining Safety) certification standards. The supplier should provide noise level ratings and vibration frequency data to ensure the equipment meets occupational health and safety regulations (OHSAS 18001/ISO 45001) to protect operators from 'white finger' syndrome.

The YT28 is designed for medium-to-hard rock (f=8-18) drilling. It is most effective when paired with an FT160BD air-leg for horizontal or inclined blast holes. If your project involves vertical downward drilling, confirm if the supplier provides a handle conversion kit or if a different model like the Y24 is more suitable.

The main risks include shipping damage to precision valves and rusting of internal components due to sea salt air. Ensure the supplier uses vacuum-sealed plastic wrapping and seaworthy wooden crates. Always verify the HS Code (typically 846711) to calculate accurate import duties and avoid customs delays.

Focus on the Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for a spare parts package (10-15% of order value) including extra pawls, rifle nuts, and water needles. For orders exceeding 50 units, aim for a 10-15% discount or request OEM branding (laser-etched logos) at no additional cost.

Utilize Secured Trading services on Made-in-China.com to ensure payment is only released upon proof of shipment. For large industrial orders, hire a third-party inspection agency (like SGS or Intertek) to perform a 'Pre-Shipment Inspection' (PSI) to test the impact frequency and air leakage before the final balance is paid.

Due to the weight of the YT28 (approx. 26kg per unit), LCL (Less than Container Load) sea freight is the most economical method. Ensure the supplier provides a Material Safety Data Sheet (MSDS) for any lubricating oil included in the package, as some carriers classify this as hazardous material. For urgent mining projects, air freight is possible but requires reinforced packaging to prevent piercing.
