Indeco breakers assist on building new Mexican roads

Indeco breakers have been proven on tough projects in Mexico, breaking out hard basalt rock

Indeco breakers have played important roles in two key road projects in Mexico, at Acapulco and Querétaro

The new road link was important for Acapulco, where traffic congestion had become a real problem for tourism in this popular holiday destination. The road connecting the centre of the city with Juan Álvarez international airport suffered in particular from frequent traffic delays. The stretch between Acapulco Bay and the Diamante and Puerto Marques suburbs was particularly bad for traffic delays.

To tackle the problem, the city authorities decided to build a 3.2km tunnel under the Cumbres de Llano Largo mountain. The contract for excavating the parallel tunnels was awarded to the Aca-Túnel consortium made up of two private companies, ICA and CARSO.

Seeing the need for hydraulic breakers in the tunnel excavation work, .the consortium approached Maquinter, Indeco’s distributor in Mexico, which sells and rents out construction machinery equipment in various different states in the Mexican Republic.

Indeco hammers had been used successfully on a previous job for ICA in Oaxaca state on a roadbuilding project. The two HP 3000 ABFs were mounted on Caterpillar 320 excavators for tunnel excavation and finishing work.

The units supplied to Aca-Túnel have since proven highly productive on the project, assisting with the tunnel excavation and finishing work.

Meanwhile Indeco also managed to supply 10 breakers to the Volvo CE dealer in a six-month period, for a series of construction works. Their first order was for three HP 7500s for CODESA, a construction company in Querétaro, 200km north of México City.

The units were employed on a project to build a 700m-long vehicle bridge with a maximum height of 7m. The breakers were used for the excavation and removal of approximately 14,000m3 of basalt.

The bridge is located in Querétaro on the road to Celaya and is known as the Balvanera Bridge. However, as the site was so close to the city, no explosives could be used, even though the basalt was particularly hard. There was also a  need to complete the job quickly so that the road could be opened up to traffic just as soon as possible.

The first three hammers proved to be a great hit, so from October to November, the company purchased another seven Indeco hammers, five HP 7500s and two HP 8000s.

While the Indeco units were not the only hammers used on the jobsite, the breakers performed well in the conditions. Another dealer had sold some demolition hammers from a competing brand in a package with four excavators.

However, the Indeco units proved their worth working 20 hours/day, which is why the contractor increased the fleet to 10 of the breakers compared with just four from the other supplier.
