Safety helmet impact tester features and technical parameters

The helmet impact tester is a full touch screen PLC control, automatic printing and data saving function, designed to test the impact resistance of human body wearing helmets in various construction, coal and other industries. This product is widely used in the production, inspection, supervision, research and use of various helmets.
When determining the impact resistance of the helmet, a special head model with a helmet is placed on a highly sensitive sensor, and then a hammer with a specified mass (5 KG) is used to impact from a height of 1 m, and a high-sensitivity force sensing device is used. Measure the force value at the moment of impact to determine the impact resistance of the helmet.

Measure the force value at the moment of impact to determine the impact resistance of the helmet.
When measuring the penetration resistance test of the helmet, the head mold is first fixed on the base so that the head mold and the puncture hammer and the electric contact display device form a closed circuit, and then the puncture hammer (3KG) is used to drop the helmet from a height of 1m. After the puncture, the electric contact display device was observed to determine the penetration resistance of the helmet.
Safety helmet impact test machine implementation standards: This product meets the GB/T2811 helmet; GB/T 2812, ISO 3847, GB/T10000 standards for test equipment requirements.

Sit In Kayak

Sit-on-top kayaks come in 1-4 paddler configurations. Sit-on-top kayaks are particularly popular for fishing and SCUBA diving, since participants need to easily enter and exit the water, change seating positions, and access hatches and storage wells. Ordinarily the seat of a sit-on-top is slightly above water level, so the center of gravity for the paddler is higher than in a traditional kayak. To compensate for the higher center of gravity, sit-on-tops are often wider and slower than a traditional kayak of the same length.

Water that enters the cockpit of a sit-on-top kayak drains out through scupper holes-tubes that run from the cockpit to the bottom of the hull. The cockpit is thus self-bailing. The hull may be sealed, or perforated by hatches and deck fixtures. Contrary to popular belief, the sit-on-top kayak hull is not self-bailing, since water penetrating it does not drain out automatically, as it does in bigger boats equipped with self-bailing systems. Furthermore, the sit-on-top hull cannot be molded in a way that would assure water tightness, and water may get in through various holes in its hull, usually around hatches and deck accessories. If the sit-on-top kayak is loaded to a point where such perforations are covered with water, or if the water paddled is rough enough that such perforations often go under water, the sit-on-top hull may fill with water without the paddler noticing it in time. If a sealed hull develops a split or hole, it will also fill and sink.
