This instrument is a standard solidifier and is suitable for use in standard Marshall tests, indirect tensile tests (split method), etc. Φ101.6mm×63.5mm（0702 type) or Φ152.4㎜×95.3mm（0702A Model) Forming of cylindrical specimens.

1. Main technical characteristics

1、This instrument is a floor-standing structure, consisting of two parts: mechanical hammer and electrical control box. The mechanical hammer transmission mechanism is driven by a motor, a reducer and a chain. Type 0702 can be used for 101.6 ㎜Test sample, 0702 A Can do 152.4 ㎜Sample.

2、The electrical circuit control box adopts a single-chip microprocessor technology, and the control panel is composed of a color LCD touch screen, with advanced design and easy operation.

3、The number of hits and downtime delays can be preset through the electrical control box. The number of hits can be (0 ～999）Select and set any within range. The instrument can automatically press and shut down according to the number of hits set in advance, automatically stop, automatically cut off the power supply, and turn off the motor, which can ensure that it can be stopped in a position that is convenient for loading and unloading of the hammer.

4、The design of a humanized manual hammer lift function makes hammer lifting operation effort-saving, convenient and safe, bringing convenience to the operator.

5、The mechanism of the test mold sleeve is used to fix the test mold sleeve to solve the problem of test mold fixing, making the test mold less easy to move, more stable, and reduce experimental errors.

6、A safety joystick is provided, so that the compaction head cannot fall when the test mold is being loaded or removed.
