SYD-0702A-1 Marshall electric scaling instrument is a special equipment for molding of specimen in the Marshall test of asphalt mixture, suitable for Marshall test of asphalt mixture ( JTJ/E20 -2011） standard. The instrument consists of two parts: mechanical transmission and control instrument, and the mechanical transmission mechanism is driven by motor, reducer, and chain. With a microcontroller microprocessor as the control core, it is equipped with a 4.3-inch colored touch display. It has real-time clock and ambient temperature detection display. It is equipped with commonly used buttons for daily operation.

1. Main technical characteristics

1、The main parts of the instrument adopt new electroplating process, with metal matte, high hardness, anti-wear and durable.

2、The electric control method is used to realize the automatic lifting and self-locking of the heavy hammer. The start button is automatically lifted, stopped and reset, reducing the working intensity for the operator and simplifying the working procedures.

3、This instrument is suitable for both use and is suitable for one machine Φ101.6mm×63.5mm The molding of cylindrical specimens can also be used for Φ152.4mm×95.3mm Forming of large cylindrical specimens.

4、The electrical control adopts large-screen color touch screen technology, and also has button control, which has double safety, is easy to operate and accurate control.

5、It has a mold precise positioning and test mold locking mechanism, and the instrument operation is safe and reliable.

6、You can set the number of hits to realize automatic hits and technology. There is also a dedicated debugging button, which is not only convenient for debugging, but also convenient for self-checking.

7、It is designed with automatic emergency stop buttons. When the instrument needs to stop working in an emergency and at any time, press the emergency stop button and the instrument stops working.
