12 GANTRY CRANES FOR A PROJECT OF TUNNELS AND VIADUCTS IN THAILAND

These gantry cranes were supplied to Stecon over the course of the last year through LGHCRANES, our subsidiary in Thailand.

Precast invert segments are a fundamental part of tunnels construction and civil work projects, given that they cover tunnel walls like a ring, thus creating a solid, durable surface.

The precast invert segments that make up the ring have different geometries, depending on their position in the ring. These precast invert segments are mounted on the tunnel to protect the shell of the shield by placing them together and screwing them in at the circumferential and radial joints.

For the Bangkok tunnels project, being currently developed by the Stecon engineering firm, a specialist in civil works and infrastructures, numerous precast reinforced concrete invert segments are required, which are stored in the yards near the pit’s access point.

The storage yards have various gantry cranes from GH Cranes to store and distribute the precast invert segments. Seven gantry cranes are in place with two 50t capacity travelling wire rope hoists and 18m lift height each. The gantry cranes have a 37.23m span. Each of these units’ wire rope hoists can work independently or in unison.

In addition to these 7 units, the location has 4 other gantry cranes, which are responsible for supplying the tunnelling machine with precast invert segments through the pit. During the drilling process, the tunnelling machine reinforces the tunnel’s walls with these precast invert segments, which means that a steady supply of segments is required in order for the tunnelling machine to continue advancing.

These gantry cranes have a 18m span, with 4m overhang on each side and a lifting height of 9.5m + 32m in the pit. Two of these cranes have a 22t capacity, and another two have a capacity of 10t. The 22t gantry cranes’ lifting speed is 30m/min, and the mechanisms are developed in work group M8. These units also stand out because of their drum safety brake.

A fifth, 2x80t capacity gantry crane is used to handle large prefab blocks.

See 2x80t gantry crane video.

For this project, GH Cranes has tasked LGHCRANES with supplying the gantry crane kits, and the company will be responsible for completing products manufacture and assembly at the client’s facilities.

Over the course of the year, various units were installed in Thailand for Stecon:

Nonthaburi storage area: Installation of seven, 2x50t gantry cranes for the production of concrete segments and blocks for a viaduct.
Bangkok, Bangna district: Installation of a 22t gantry crane for a pit (mud extraction works, tunnelling machine, and precast invert segments), and a 10t gantry crane with a 18m span and M5 lifting height of 9.5m for a stock storage area.
Bangkok, Prawet district: Installation of a 22t gantry crane to supply precast invert segments to the pit.
Bangkok: Installation of a 25t overhead crane with 8m span and a lifting height of 61m.
Chonburi: One gantry crane that had already been supplied but not installed, and another 10t gantry crane.

In addition to these facilities, other units have been manufactured in recent years for Stecon projects:

In 2014, Nonthaburi province: Installation of the first, 63+63t gantry crane with a 36m span for segments production.
In 2016, the same Nonthaburi storage area: Four, 5+5t bridge cranes for auxiliary work.

WHEN THE JOB DOESN’T END WITH THE MANUFACTURING PROCESS

Locomotive loading and lifting tests with two new gantry cranes for Stadler Valencia.

This company, located in the Valencian town of Albuixech, has an important presence in the Spanish market, as well as numerous international contracts.

A specialist in the design and manufacture of locomotives, as well as urban and regional trains, Stadler Valencia employs 900 professional staff, of whom almost 200 are dedicated to the innovation and design of railway vehicles.

Since Miguel Devís Pérez and José Noguera Chuliá created Talleres Devís y Noguera in December 1897, what is now the Stadler plant has evolved to become one of the leaders in the design and manufacture of rolling stock in Spain.

The company remained at the forefront when it began to build trams and electric and steam locomotives more than a century ago, incorporating diesel models from 1959 onwards. During the 1960s and 1970s, the company sold 300 locomotives to Renfe and another 300 were sold on the international market, which meant the growth and consolidation of the company as one of the major European railway manufacturers. During the years in which it has been operating, the company has sold more than 2,000 vehicles in 18 countries.

Stadler has been present in Spain –in Valencia– since 1 January 2016. That day, Stadler bought the Vossloh Spanish locomotive business and thus added to its ranks a company that perfectly completed the Stadler Rail product portfolio, also offering access to new markets. The facilities in Valencia, with an area of 200,000 m2, include offices, production plants, storage areas and vehicle inspection and testing areas.

At the event to commemorate the 120th anniversary, celebrated in December 2017, Íñigo Parra, president of Stadler Rail Valencia, insisted that “This plant has become one of the great industry leaders in Spain, where we have been able to add value to our products through the continuous investment we make in innovation and design.”

The company has recently been awarded various locomotive contracts both in Europe and in South America, as well as light rail/tram contracts for different European regions – including the modernisation of Alicante’s Line 9, which connects Benidorm and Denia. To meet the demand for production, Stadler Valencia asked GH Cranes for two new gantry cranes, which have been installed outside the Albuixech warehouse.

Locomotive loading and hoisting tests have recently been carried out on these gantry cranes with a span of 5.1 m, equipped with hoists with a capacity of 2×40 t, which can work in either an independent or synchronised way.

Here at GH Cranes, we are comprehensive manufacturers of all our products; however, our work does not stop with the mere manufacture of cranes and hoists. Our work begins with the initial proposal and ends with the maintenance and spare parts service; and it includes engineering, manufacturing, transport, assembly and commissioning of the manufactured products.
