The LC-300B drop hammer impact tester is suitable for measuring the external impact resistance of various pipes (water supply pipes, sewage pipes, low-pressure water supply pipes, low-pressure water pipes, core foam pipes, double-wall corrugated pipes) and plates. Standards Compliant: JB/T9389, GB/T14152, GB/T14153, GB/T6112, GB/T5836, GB/T10002.1, GB/T10002.3, GB/T13664, GB/T16800, GB/T18477. Instrument Features: 1. Digital display of impact height, with functions such as automatic hammer suction, automatic zero alignment, automatic lifting, and automatic secondary impact prevention. 2. Pre-arrival height and zero point adopt two test speeds, running at high speed during long-distance ascent or descending, which can save the remaining test time. When the hammer is close to the pre-arrival height, the motor will automatically switch to low speed to avoid motor inertia. Height positioning deviation. 3. This machine uses chain to drive up and down. The chain, sprocket and motor are matched to avoid the winding phenomenon caused by wire rope transmission. 4. Double-tube structure, safer and more reliable in operation. Technical Parameter: 1. Maximum impact energy: 300J 2. Weight of hammer body: 0.25kg-15.000kg 0.125kg/increment 3.
