Electric Lab Soil Multifunctional Compactor Factory Suppliers in China
High-precision electric lab soil multifunctional compactor from leading China factory suppliers. Ideal for water conservancy, railway, and airport foundation engineering to determine dry density and moisture content. Supports CBR and resilience modulus tests with automated digital counting.
Product Overview
The Lab Soil Multifunctional Compactor is a high-precision electric instrument designed for foundational engineering construction across water conservancy dams, highways, railways, airports, and general building projects. By employing standard compaction methods, this versatile apparatus allows engineers to accurately determine the relationship between density and water ratio, confirming the critical dry density and moisture content of soil samples.
Engineered for versatility, the system supports both light and heavy compaction and is fully compatible with CBR and resilience modulus tests. Featuring an upgraded rack-and-pinion drive system to eliminate hammer drop issues, it integrates digital displays, automatic counting, and cyclic operation to maximize testing efficiency and ensure strict compliance with JTG3430 – 2020 and other national standards.

Frequently Asked Questions
This instrument complies with the industry standards of the People’s Republic of China (JTG3430 – 2020), as well as specific Ministerial, National, and Water Conservancy standards for both light and heavy compaction.
Yes, it is specifically designed to satisfy the specimen preparation requirements for California Bearing Ratio (CBR) tests and resilience modulus tests.
The rack-and-pinion system avoids common issues found in chain-drive systems, such as dropped hammers or hammers that fail to lift, ensuring smoother and safer continuous operation.
No, compaction moulds need to be ordered separately to match the specific test cylinder sizes (e.g., φ100mm, φ152mm) required for your project.
By performing multiple tests at varying moisture levels, the machine allows for the accurate plotting of curves between water content and dry density to identify the optimal moisture point.
The instrument is designed for use in both environments, including traffic scientific research departments, universities, construction unit laboratories, and on-site field tests.
