Texmaco Rail & Engineering Ltd. in Kolkata, India's largest railway truck manufacturer, has placed an order to refurbish eight overhead travelling cranes using Demag engineering. Demag Service India first subjected the crane installations to a comprehensive inspection (Professional Crane Audit) after which it developed a detailed upgrade concept. The plan is to refurbish the cranes step-by-step in such a way that day-to-day operations at Texmaco are not interrupted. The order involves installing tried-and-tested Demag components from Terex MH’s established product range.
“The refurbishment concept Demag Service presented to us was utterly convincing”, enthused D.H. Kela, President and CEO at Texmaco Rail & Engineering. “Once they have been converted, these cranes will provide higher reliability and safety to handle increased production. In Demag service we have selected a qualified partner who is in a position to support us and boost the safety, reliability and performance of our crane installations. In addition to this, Demag engineering has a good reputation with Texmaco as a result of the Texmaco UGL joint venture which successfully uses Demag crane technology.”
Manojit Acharya, Executive Director of Terex Material Handling (Terex MH) India explained: “By implementing this holistic refurbishment approach, we are laying the foundations for our customer to secure a future-orientated investment. In doing so, we do not just concentrate on individual crane components, we consider the entire crane installation as a unit and its interface with the manufacturing & lifting processes. It was not only our detailed breakdown of the steps to refurbish the cranes that was decisive in winning this order, but also the impressively broad range of products we can supply. This flexibility allows us to provide tailor-made solutions whether it is a new crane project or a service solution.
“This refurbishment project is a significant order for Demag Service and emphasises the faith customers have in our solutions. Highly dedicated, qualified Demag Service engineers and fitters will be carrying out the work to meet the agreed schedule.”
Professional Crane Audit
A refurbishment project is based on a comprehensive Professional Crane Audit (PCA), which exactly defines the status of an installation. An audit of this type, of which this was the first performed in India, involves detailed, in-depth inspection of the crane installation and an analysis of the data recorded in the process. In a subsequent consulting meeting, the customer is informed in detail of all the actions required to refurbish and upgrade his cranes to ensure that the installation is both safe and economical in the future. The objective of the actions recommended after a PCA is to increase the safety, performance and availability of a crane installation while reducing overheads. Manojit Acharya confirmed: “Texmaco’s order shows that the Indian market appreciates professional advice and services. We are able to offer both these commodities and are thus supporting Texmaco in their aim of maintaining the value of their investment long-term.”
About the refurbishment project
At the Texmaco production facility in Kolkata, industrial cranes are used for the in-plant transfer of materials within the eight bays. The cranes, some of which are 60 years old, were originally made by various local manufacturers and have load capacities of 5 to 40 tonnes. To secure their availability for coming years and to lower overheads, Texmaco decided to go for a full-scale refurbishment programme and opted for implementation of the concept proposed by Demag Service.
That concept, developed specifically for Texmaco, involves replacing the drive and control technology in the double-girder overhead travelling cranes. The crane and trolley travel units on the larger crane installations are to be fitted with wheel block systems from the DRS range that has been tried-and-tested worldwide.
In addition to these features, new power supplies and new control modules are included in the refurbishment of the Texmaco cranes, as are radio control units which can be used on a master/slave basis as an alternative to the controls in the cab. In the context of the refurbishment operation, the bottom blocks and load hooks will be replaced and a spare parts management system implemented.
Once the entire operation has been completed, the cranes will be both more efficient and safer. The supply of spare parts will then also be secured in the medium term due to the large number of new components. The cranes will be more productive because there will be fewer unscheduled downtimes. In addition, this state-of-the-art drive technology will also reduce the cranes' energy consumption.
A quarter of all freight trucks (railway wagons) manufactured in India come from the Texmaco Rail & Engineering Ltd. based in Kolkata. Besides this product, the enterprise, which is a part of the Indian Adventz Group, manufactures pressure vessels, cryogenic storage vessels, steel castings and heavy steel fabrications for, amongst other things, bridges, power stations and other infrastructure projects. The enterprise, founded in 1939, has a high level of vertical integration, as can be seen, for example, by the fact that it has its own state-of-the-art foundry with an annual capacity of 30,000 tonnes. Part of the group is engaged in another joint venture with internationally orientated rail truck makers who also manufacture passenger coaches & locomotives.
