STMJ-1 Digital Marshall Electric Compactor
STMJ-1 Digital Automatic Marshall CompactorSTMJ-1D Digital Large Automatic Marshall Compactor
1. Application: This compactor is the special equipment used for specimen formability of asphalt mixture for marshall testing. It is apply to asphalt mixture marshall testing standard (JTJ052-2000).
2. Characteristic:
It is consisted of mechanical drive and control equipment, to improve reliability of whole machine. In order to guarentee the safety of working, all the transmission components and heavy hammer are installed inside the case of compactor.Mechanical drive is including motor, reducer, chain drive. Circuit controller has integrated circuit and can pre-set the counter.The counter can be selected in the range of 0~9999 freely and has momory function.There have pre-set number button, digital display and stop button on the instrument panel.Can pre-set the compaction times before working, once reach the compaction times, it will be shut off the power and motor automatically.3.
