The Lima Metro Line 2 is currently the biggest infrastructure project in Peru. The line 2 will have the capacity, once completed, to transport up to 660,000 passengers a day.

This infrastructure will help to improve and protect the environment by increasing air quality and by reducing emissions.

The first section of  Lima Metro Line 2 is supposed to be operational by 2020 while the fill line should be ready by 2024. Line 2 will also be connected to Jorge Chavéz International Airport throught the interconnection with Line 4.

The project for the construction of Lime Metro Line 2 is divided into line 2 (27km) and part of line 4 (8km) for a total of 35 km of underground tunnels.

STM designes and realizes a sloped conveyor system for muck elevation from the tunnel conveyor to the surface, with an external tripper conveyor equipped with stacker, unloading the tunnel muck along the continuous pick.

Conveyor systems provide an efficient, reliable, cost-effective and lower-risk method for removing muck and spoil from tunnelling excavation sites. Thanks to its core competencies, know-how, and on-going investment STM is able to provide to its customers continuous conveyor.

The continuous conveyor is globally recognized as the most efficient and effective solution for the handling of material extracted by tunnel boring machine (TBM). This equipment is specifically engineered to smoothly handle the transport of materials from the tunnel excavation site to the surface and beyond. Large belt storage capacity increases TBM utilization, reduces construction time and generates lower costs.


STM successfully reached these outstanding achievements thanks to its distinguishing features: expertise in every area of activity, strong focus on the customer, passion for innovation and improvement and particular attention to the quality.
