1. Realtop has more than 10 years experience on manufacturing Pipe Jacking Machinery(TBM),
2. Remote-controlled Slurry Balance Pipe-Jacking Machine is a new advanced non-digging-equipment with high technology.
3. It combines multi-disciplinary technologies in one, such as the machinery units, hydraulic system, electric controller (including PLC), Laser system, measuring device, etc.
4. Besides the high efficiency, it also has effect on the traffics on surface. Furthermore, it is good for the environment, and can lower the cost of the construction.
5. Projects in Singapore,Thailand,Hongkong,etc.. Export to Singapore from 10years ago;
1. On site service support;
we could supply pipe jacking machine model from DG250mm to DG5000, not only for round shape and rectangle shape.
