Dear Madam./Sir
Thanks for your interest! I am Ms. Aileen Zhu from Realtop, a specialized manufacturer for pipe jacking machines in south China.
Our Products Advantages:
Pipe-Jack Machine;
Fit for trechless underground pipe laying;
Easily control above ground;
continuous work,
Fast speed safe!
Dameter from 250-3000mm
1. Introduction:
Remote-controlled Slurry Balance Pipe-Jacking Tunneling Machine is a new advanced non-digging-equipment with high technology.
It combines multi-disciplinary technologies in one, such as the machinery units, hydraulic system, electric controller (including PLC), Laser system, measuring device, etc.
Besides the high efficiency, it also has no effect on the traffics on surface. Furthermore, it is good for the environment, and can lower the cost of the construction.
