Reversible vibratory plate compactors are for the compaction of sand & gravel, crushed aggregate as well as mixed soils with some cohesive content. They are ideally suited where forward-reverse operation is required such as in trenches and backfilling along foundations. These compactors increase compaction force over standard plates due to two eccentric weights instead of one. These versatile units are suitable for compacting a variety of surfaces including granular soils, gravel, and crushed aggregate.

Reversing Contactors are used for a three-phase motor. It provides both forward and reverse motor control. It has fixed-mounted contact parts that serves input and output connection by contact bridges from input to output. A common drive mechanism is provided for all the contact bridges and shift mechanism to change the configuration of the contact bridges. The application of the two independent movable contact bridge carriers, which is used by an auxiliary magnet. It can be selectively brought into functional contact with the common drive mechanism by a reversing yoke. The major wiring work can be performed by formed fixed-mounted contact parts.
