XDN400H full hydraulic pipe jacking machine is the smallest diameter full hydraulic pipe jacking equipment in China. It helps local residents obtain clean and safe drinking water in Tanzania, East Africa.

The construction site in Tanzania is nearly 500 meters away from the road section, which does not have excavation conditions, and the underground construction of the pipe jacking machine needs to experience fine sand, coarse sand, silt, laterite, clay, hard clay, weathered rock, backfill and other strata. This places extremely high demands on the overall performance of the pipe jacking machine.

In order to ensure the smooth progress of the project, XCMG sent professionals to provide guidance, and at the same time cooperated with the project department to continuously optimize the construction process. XCMG's pipe jacking machine was jacked in inch by inch. The construction of nearly 500 meters was successfully completed, and the construction period was 4 months earlier than the original plan.

● XCMG XDN400H full hydraulic pipe jacking machine applies graded reverse jacking technology, and the minimum diameter of the starting well can reach ∅2590mm, reducing customer costs;

● Hydraulic motor and reducer apply integral mechanical seal, which has good waterproof and moisture-proof performance, especially suitable for construction under the surface water with abundant rainfall;

● Double-pump confluence, fast idle speed and short construction waiting time;

● The rotary speed and jacking speed of the cutter head are steplessly adjustable, and the stratum adaptability is strong.

At present, XCMG's pipe jacking machines have been successfully applied in key overseas projects such as Brazil, Indonesia and Malaysia.
