Marshall Electrical Compaction Apparatus GD-0702A

Features :

1. The marshall compaction apparatus is a floor structure consisting of mechanical hammering and electrical control box. The mechanical hammering transmission mechanism is driven by motor, reducer and chain. Type 0702 can be used for 101.6mm test, and 0702A can be used for 152.4mm test.
2. The electrical circuit control box adopts the single chip microprocessor technology and the control panel is composed of a color  LCD screen. The design is advanced and the operation is convenient.
3. The number of hits and stop delays can be preset via the electrical control box. The number of hits can be arbitrarily selected and set in the range of (0 to 999). The instrument can be automatically compacted according to the pre-set number of shots, automatically stop, automatically cut off the power supply, and shut off the motor, and it can be ensured to stop at the position where the lifter is convenient for loading and unloading.
4. The design of humanized manual lifting hammer function makes the lifting hammer easy to operate, convenient and safe,  and brings convenience to operators.
5. Adopts the mechanism of pressure ring fixed type mold to solve the problem of trial mould fixing, make the trial mould not easy to move, more stable and reduce experimental errors.
6. With safety lever, when the test mode is being loaded or withdraw, the compacting head can not be dropped.
