12 gantry cranes for a project of tunnels and viaducts in Thailand

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.

WIN-WIN top customers programme and regional seminar in Bangkok

WIN-WIN TOP CUSTOMERS PROGRAM AND REGIONAL SEMINAR IN BANGKOK

Seminar in Thailand to present the technological innovations that GH Cranes incorporates into its equipment.

On 20 and 21 July GH organised a double meeting with top-level Thai customers to present the latest developments and technological innovations incorporated into our equipment. The meeting also served to give a broad overview of GH capabilities in the country and to introduce our integrated team in the joint venture we have with Peera Lohakarnlyon: LGH.

In another of the sessions, all the distributors from Southeast Asia, South Korea, New Zealand and Australia met together so that they could be provided with the same information that was given to the customers and with the aim of improving interaction by listening to their ideas and suggested areas for improvement.

The two seminars were held at the LGH premises in Chonburi and both customers and distributors could see first-hand the improvements to our new GHE17 hoist, the regenerative hoist and other technological developments that GH has incorporated into its products.

To round off, both groups were offered a tour of the production facilities where they were able to inspect the crane manufacturing process, as well as the quality standards and reliability requirements for our cranes.

The two events served to confirm the commitment of GH to this geographical area of ​​the world and to acknowledge the presence of a great team of people willing to give the best possible service based on their proximity to customers.

It is only a small step in terms of the presence of GH in Southeast Asia, but a great leap for the stimulation of our activity in the area, which we are confident will bring its rewards.

Seminario en Tailandia para presentar las novedades tecnológicas que GH Cranes incorpora a sus equipos.

Los pasados días 20 y 21 de Julio GH organizó un doble encuentro con clientes tailandeses de primer nivel para presentar los últimos desarrollos e innovaciones tecnológicas incorporados a nuestros equipos. El encuentro sirvió además para dar una visión amplia de las capacidades de GH en el país y nuestro equipo integrado en la Joint Venture que tenemos con Peera Lohakarniyon: LGH.

En otra de las sesiones se reunió a todos los distribuidores del sudeste asiático más Korea del sur, Nueva Zelanda y Australia para ofrecer la misma información que a los clientes y para logar interactuar mejor escuchando sus ideas y áreas de mejora.

Los dos seminarios se llevaron a cabo en las instalaciones de LGH en Chonburi y tanto clientes como distribuidores pudieron palpar “in situ” las mejoras de nuestro nuevo polipasto GHE17, el polipasto regenerativo y otros desarrollos tecnológicos que GH ha incorporado a sus productos.

Para finalizar a ambos grupos se les ofreció un tour por las instalaciones productivas en las que pudieron comprobar el proceso de fabricación de las grúas, así como los estándares de calidad y exigencia de fiabilidad en nuestras grúas.

Los dos eventos sirvieron para confirmar la apuesta de GH por esta área geográfica del mundo y la constatación de la presencia de un gran equipo de personas dispuestas a dar el mejor servicio posible desde la cercanía a los clientes.

Es tan solo un pequeño paso en la presencia de GH en el sudeste asiático, pero un gran salto en el estimulo de nuestra actividad en la zona, que seguro que dará sus resultados.
