Product Overview
YTQH350CS delivers 350 t·m of compaction energy, which is the number geotechnical engineers compare when a site report calls for impact energy at depth. The machine is built around the drop mass and stroke that produce it.

Performance Feature
350 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 YTQH350CS-1 Dynamic Compaction Machine
Yutong's YTQH350CS-1 is a dynamic compaction unit rated at the rated of drop energy per blow, built for foundation improvement on fills and collapsible ground where depth of densification is set by the site investigation.
Energy settings are verified before delivery: the mast is braced for the full stroke range, the base spreads each blow across the carrier, and the drop charts in the manual match the site work the machine is specified for.
For the YTQH350CS-1, Yutong sizes energy and drop mass from the site investigation, then supports the unit with spares, training and field service across the markets it serves.

View DetailsEngineering & Application Notes
The YTQH350CS-1 is specified against its daily duty: the rated gross mass, the rated power and the rated capacity with the body, electrics and HVAC matched to the work, not adapted from a stock truck. Operators use the YTQH350CS-1 where the duty cycle decides the configuration, and the body loads are documented against the chassis bracing.
Compaction for collapsible fills
The YTQH350CS is the dynamic compaction unit for collapsible fills and reclaimed ground, where the drop energy per blow sets the depth of densification the geotechnical report requires. The mast and winch cycle keep the drop cadence, and the energy per blow is calibrated against the site investigation. Contractors use it on the industrial plots and storage yards where foundation improvement is done before the building loads are placed.
Frequently Asked Questions
What compaction energy does the YTQH350CS-1 Dynamic Compaction Machine deliver?
The YTQH350CS-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.
