Schwing – XCMG Tower Cranes

Posted on

Tower Cranes- The Way Forward

Schwing Stetter (India) Private Limited has launched five- and six-tonne tower cranes branded Schwing-XCMG. The Schwing-XCMG cranes are from XCMG, a Chinese manufacturer of cranes and one of the largest in the world, which holds a 60 per cent stake in the Schwing Stetter holding company in Germany.

Anand Sundaresan, Vice-Chairman and Managing Director, Schwing Stetter (India), said at the product launch marks the diversification of the product base for the Indian subsidiary. This entity was so far only in concrete handling equipment such as concrete pumps, truck-mounted mixers and batching plants. In line with the anticipated growth in infrastructure development and construction industry here, the company had decided on launching two models of tower cranes. The cranes will initially be imported but will eventually, over the next year or so, be mostly manufactured locally. The five-tonne capacity tower crane is the most in demand in the domestic market, followed by the six-tonne crane.VG Sakthi Kumar, Managing Director, Schwing Stetter Sales and Services Private Limited, said the five-tonne unit, XGT63YD (5013-5), will be priced at about Rs.60 lakh and the bigger version XGT100YD at Rs.90 lakh.

The working mechanism of the tower cranes includes a central mast, attached to which is the slewing unit of the machine that acts as the unit motor. The slewing unit of the machine helps in movement of the arm part of the crane and lifts up objects by moving a full 360 degrees and lifting objects from one place and putting it down at another. The operation of the crane is very simple but the movement of crane is tedious and requires a lot of time. The benefits of tower cranes are that it can lift objects up to 200 meters and it can lift objects weighing up to 10,000 kilograms.

Gulf Oil, Schwing Stetter tie up to market co-branded lubricants

Posted on Updated on

Schwing Stetter and Gulf Oil Lubricants India Ltd (a Hinduja Group Company) have inked an agreement to market co-branded lubricants for Schwing Stetter customers across the country.

This is in addition to the factory fill which is already being supplied by Gulf Oil. The agreement was signed by Ravi Chawla, Managing Director, Gulf Oil, and Anand Sundaresan, Vice-Chairman & Managing Director, Schwing Stetter, according to a statement made to the BSE.

Schwing Stetter India is a 100 per cent subsidiary of the Schwing Group of companies, which is a pioneer in the manufacture of concrete construction equipment.

Gulf Oil Lubricants India is one of the leading private sector players in the lubricant industry and currently is the fastest growing lubricant marketer in India.

Anand Sundaresan said: “After field trials for several months on our concrete pumps, we have approved use of ‘Gulf Harmony AW 68Plus SS’ for our equipment. We are glad to enter into an agreement with Gulf Oil for factory fill as well as aftermarket business. I am sure our customers will greatly benefit with this association.”

Ravi Chawla said, “This further strengthens our presence in the construction sector, which is a key segment for India’s growth and one of Gulf oil’s key focus segment in the coming years. Our products and services have been designed keeping in mind the extreme working environment of construction and mining Industry. Our team is fully prepared to deliver total customer satisfaction.”

The co-branded lubricants have been specially formulated for Schwing Stetter equipment and will meet its stringent engineering specifications. The portfolio includes high performance anti wear hydraulic oils made from severely hydro cracked and hydro treated Group II base stocks with special performance additives.

Schwing Stetter in Go Green projects

Posted on Updated on

Concreting GREEN Energy:

Every developed nation looks up to India; here a windmill was built as early as 1730 at Horse Tail Point in Cuddalore. Concrete as a material of construction can play an important role in realising the potential of wind energy. The trend towards increasing generating capacity of windmills makes concrete a competitive material. Concrete as material of construction is durable.

 India ranks fifth amongst top ten wind power producers in the world. As on 31 March 2015, the installed capacity of wind power in India was 23,444 MW, mainly spread across Tamil Nadu (7,253 MW), Gujarat (3,093MW), Maharashtra (2,976 MW), Karnataka (2,113 MW), Rajasthan (2,355 MW), Madhya Pradesh (386 MW), Andhra Pradesh (916 MW), Kerala (35.1 MW).

Out of which, Tamil Nadu continues to maintain No.1 position in the country in wind power with 42% of total installed capacity in India. Currently, windmill projects are running in various parts of the country where Schwing Stetter equipment’s are in action.

Schwing at Windmill Projects:

Schwing Stetter has always been on the forefront for concreting Green Energy projects –a place where clean energy is produced with no emission of hazardous waste and no consumption of fossil fuels. Wind Energy is the least expensive form of renewable energy.

The company Enercon is a pioneer in the construction of wind power stations and their integration into the power grid. The focus here is on considerable higher nominal outputs of the generators and thus on greater heights of the rotor hubs. The rated output of the plants has risen in the last few years from 600 kW to 7,500 kW and the height of the rotor hubs from 45 m to 136 m. In order to make the foundations fit for withstanding all the higher static and dynamic loads, their volumes had to be enlarged accordingly. These heavy-duty foundations require nowadays up to four times as much concrete as the foundations 10 years ago.

Concreting the Windmill:

Concreting is the major work in the windmill tower construction. Schwing Stetter equipment’s are used for concreting their windmills across India. The windmill projects consist of various concrete structures and types, which are considered to be a very challenging task. Depending upon the site conditions both in-situ and pre-cast construction methods have been used for the wind tower construction.

The Construction work in these projects consists of precast concrete towers, which are made using specially developed pre-stressed steel reinforcement. The individual tower sections and foundation are fastened together to form an inseparable unit with stay cables running through jacket tubes in the core of the concrete tower wall. Tubular steel tower, Tubular concrete, Lattice tower, Three legged tower, Guy wired tower, Hybrid tower are the different types of the wind tower.

The tower sections are manufactured in a pre-casting plant. The pre-casted segments of tower sections are prepared by casting concrete in reusable molds in a controlled environment. Specially constructed steel moulds assure manufacturing precision for each individual concrete section. This manufacturing process minimizes dimensional tolerances, which assures a high degree of fitting accuracy.

The advantages of pre-stressed concrete towers include stiffness in case of extreme load capacity, better fatigue properties over steel, unlike steel tower there is no risk of buckling and lower material cost. The foundations are circular. The piles, symmetrically arranged, are slightly inclined so that the imagined extended pile centerlines meet at a point above the center of the foundation.

This provides maximum force/load distribution over the entire surface. The post-tensioned segmental concrete tower design consists of a number of arc segments that combine to form circular sections that are stacked on each other and made to act together in a monolithic manner by post-tensioned high strength tendons that pre-compress the concrete so that it is nearly always in compression to applied loads.

The Towers are made from M55 grade concrete. Schwing Stetter’s Batching plants like HN2.25 with Stetter pan mixer and wirvler along with two discharges are used for precasting the tower and the circular foundation.

Windmill towers are constructed using massive amounts of concrete in which our Schwing stetter batching plants, truck mounted boom pumps contributions are enormous. The prolonged service life of concrete and its ability to cope with increasing loading allows possible retrofitting of turbines after their initial 20 year design life. Therefore, longevity from the concrete avoids the financial and environmental costs of construction.
