In brief
Putzmeister at construction sites in India
Essar Oil Refi nery in Jamnagar:
Four truck-mounted
concrete pumps in action
Essar is using the fi rst Putzmeister M 42-5
in India to concrete one of the largest refi
neries in the world at Jamnagar in West
India. Together with three of the eight
M 36 pumps from the fl eet, the “new” edition
pumps reliably throughout the day
and night.
The Putzmeister India After Sales & Parts
Service is regarded highly by the people at
Essar, but the message from Deepak Kumar
Singh, Managing Director of Essar HED, is
clear: “For me, the machines by Putzmeister
are simply the best for concreting.”
