Semi-Automatic Compactor Manufacturer,Supplier and Exporter in India
Product Code : EL-STLE-13001
Quick Answer: The Semi-Automatic Compactor is a mechanically and electrically operated compactor that replaces hand compaction of soil: a pawl releases the rammer at the required height, it falls freely on the soil, and an automatic blow counter sets the number of blows. Two stroke lengths are available for normal, heavy and C.B.R. compaction.

About This Product
Soil is compacted in a mould in layers by a rammer dropped from a fixed height, and the blows are counted for each layer. A semi-automatic compactor does this mechanically: the motor lifts the rammer, a pawl lets it fall freely onto the soil, and the base plate rotates with each stroke. In civil engineering labs it is used for normal and heavy compaction tests and for C.B.R. specimens, with the blow counter set to the required number. Related equipment for the same test includes the Proctor Compaction Test Apparatus. School Lab Equipment India can export the Semi-Automatic Compactor to education buyers in Benin, Samoa, Burkina Faso, Montenegro, Venezuela and Tajikistan.
Frequently Asked Questions
Q1. What types of compaction can the Semi-Automatic Compactor perform?
With the two available rammer stroke lengths it can be used for normal compaction, heavy compaction and C.B.R. compaction.
Q2. How does the rammer operate?
When the rammer reaches the required height the pawl releases it and it falls freely on the soil surface. An arm moving up and down, connected to a reduction gear coupled to the motor, operates the release mechanism, and an automatic blow counter sets the number of blows.
