1. Chain injury of chain hardness tester
The diameter measuring range of chain hardness tester has been determined by the configuration of the instrument when leaving the factory. It is strictly prohibited to use beyond the scope. In particular, the use of 29420 N (3000 KGF) test force, when testing large diameter material beyond the range, it will cause hook deformation and chain decoupling, the chain will be taut off instantly, leading to serious personal injury. Therefore, the following safety regulations should be strictly observed:
2. When ordering, order a suitable instrument according to the test force and the diameter range of the workpiece, and the diameter of the measured workpiece shall not exceed the allowable range.
3. When measuring, the operator should avoid the direction in which the chain may break.
4. The hook rod clamps hand.When using chain hardness tester, please do not hold the hook bar. If the chain adapter falls over after hanging one side of the hook, the hook rod and chain adapter will pinch the finger
The above precautions for the use of chain type PHB-3000A hardness tester are the experiences and lessons summed up by us and our customers in actual use. Please read and execute these precautions carefully to ensure personal safety and machine safety.
