•    Complies with GB/T 27906-2011 "Lifesaving Throwing Device" standards. The lifesaving throwing device is a compressed air pipeline device primarily used for throwing lifesaving ropes, lifebuoys, or anchor hooks over long distances. It can be used with different objects for various functions. It is applicable in firefighting, swift water rescue, offshore drilling, deep-sea fishing, rapid response teams, naval vessels, and industrial safety. Powered by high-pressure air, it can quickly and accurately launch ropes or auto-inflating lifebuoys. Available in both water and land versions.
o    Equipped with a pressure gauge to display the inflation pressure.
o    Basic technical parameters:
    Appearance: The surface of the throwing device should be smooth with no burrs, and all components should be undamaged.
    Structural requirements:
    (1) The throwing device is equipped with a pressure gauge, with a range sufficient to meet work requirements. Accuracy must not be lower than grade 1.6.
    (2) The device has a launch safety mechanism, with a separate action from the device's activation.
    Throwing performance:
    Throwing distance (m): Rope throw: 335m, Water rope throw: 223m.
    Throwing deviation angle (°): Rope throw: 0.44°, Water rope throw: 0.54°.
    Metal parts corrosion resistance: After corrosion resistance tests, there should be no obvious corrosion, and the device should still meet throwing performance requirements.
    Reliability: After reliability tests, no components should fall off or be damaged.
    Sealing performance: During sealing tests, no leakage should occur in pressurized parts of the throwing device.
    Safety valve: The safety valve's opening pressure should be 1.1 times the rated working pressure, with a tolerance of no more than ±0.5 MPa.
    Pressure resistance: After pressure resistance tests, no leakage or deformation should occur in pressurized parts of the device.
    Throwing objects: Appearance: The rope and water rope should have no damage, breakage, fraying, or tangling.
    Length (m): The rope and water rope should be no less than 1.15 times the rated throwing distance.
    Breaking strength (kN): According to XF494-2004, the rope's breaking strength should be no less than 2 kN, and the water rope's breaking strength should be no less than 6 kN. Rope: 2.35 kN, Water rope: 6.86 kN.
    Water rope buoyancy: After buoyancy tests, the water rope should float on the water surface.
    Other lifesaving equipment: Other lifesaving devices should comply with relevant standards.
