Product Overview
The YTQH450CS is a high-energy dynamic compaction machine sized for deep foundation improvement: 450 t·m of rated energy per blow lets it densify fills and soft soils to the depths a PVD or stone-column spec demands.

Performance Feature
450 t·m of energy per blow is the figure the geotechnical report compares against the required depth of improvement.
Drop mass and stroke are tuned to produce that energy reliably over a long shift, with the impact sequence managed from the cab.

About the YTQH450CS-1 Dynamic Compaction Machine
YTQH450CS-1 is a dynamic compaction compaction unit delivering the rated per blow — the figure the geotechnical report compares against the required depth of improvement, with the base machine, mast and winch matched so each drop lands square.
Drop mass, stroke and mast bracing are set at the factory, and the base machine is reinforced to spread impact loads across the carrier. The unit is run through its energy range on the proving ground, and the drop charts ship with the machine for site use.
Choosing the YTQH450CS-1 begins with the geotechnical report: Yutong confirms energy, drop mass and pattern from the depth of improvement required, then configures the machine, mats and service plan for the site.

View DetailsFrequently Asked Questions
What compaction energy does the YTQH450CS-1 Dynamic Compaction Machine deliver?
The YTQH450CS-1 Dynamic Compaction Machine delivers compaction energy ranging from 350 t·m to over 1200 t·m depending on the model. This energy is sufficient to treat loose fills and soft soils to depths of 5-10 meters or more, significantly improving bearing capacity and reducing settlement.
What types of soil can be improved with dynamic compaction?
Dynamic compaction is effective for loose granular soils, gravel fills, sand deposits, collapsible loess, and miscellaneous fill. It is less effective for very fine saturated clay without prefabricated vertical drains. A site investigation and trial compaction program is recommended for optimal results.
What construction projects is this machine suitable for?
Yutong dynamic compaction machines are widely used for airport runways, port container yards, industrial plant foundations, highway embankments, reservoir dams, and large-scale land reclamation projects. Any project requiring deep ground improvement can benefit from this technology.
How does the electric/range-extended version compare to diesel?
The range-extended electric dynamic compactor delivers the same compaction energy as the diesel model while reducing fuel consumption by up to 30-40%. It produces lower noise and zero local emissions, making it suitable for urban and environmentally sensitive project locations.
What is the typical productivity rate?
Productivity depends on the required compaction energy and grid spacing. Typical rates range from 500 to 2000 square meters per day per machine. A test section is usually performed first to determine the optimal number of passes and energy level for your site conditions.
Does Yutong provide on-site technical guidance?
Yes, Yutong provides on-site commissioning and technical training for dynamic compaction projects. Our engineers can advise on tamping parameters, grid layout, and quality control methods to ensure optimal ground improvement results.
Does Yutong export to my country?
Yutong Heavy Industries exports construction machinery to over 60 countries across Asia, Africa, the Middle East, South America, and Eastern Europe. We have established dealer and service networks in major markets. Contact us to confirm availability in your region.
