THE DANISH COMPANY CONFAC COMBINES A COMPREHENSIVE SYSTEM OF DIFFERENT LIFTING SOLUTIONS

Integral solutions adapted to the needs of the client.

Thinking globally allows us to offer specific solutions that can be adapted to the requirements and working systems at our client’s facilities.

This is the case for the combination of products that have been installed at the facilities of the company CONFAC in Denmark. CONFAC is a company that manufactures precast concrete for housing construction.

The system for manufacturing and storing the parts required four bridge cranes, a transfer cart and an external gantry crane, all working together in a continuous and timed process.

The cranes used in the mould-handling process and for the manufacture of the pieces, which are transported outside using a transfer cart and then finally stored in the exterior patio using a gantry crane, are installed in the main hall.

The cranes have drives for all movements, which allow smooth movement of the load and increased speed when the crane is working with 25% of the load capacity.

The characteristics of the products installed are as follows:

25 t and 20 t bi-rail bridge cranes, with 24 m span.
7.5 t and 3.2 t bi-rail bridge cranes.
10×3 m transfer cart with capacity of 60 t.
25 t gantry crane with 30 m span and 10 m cantilevers. It has electric rotation in the hook to make handling the pieces easier.

This project has been managed by Certex, our official distributor in Denmark.

TRANSBORDADOR FERROVIARIO PARA LAS NUEVAS INSTALACIONES DE CAF EN NEWPORT

Newport se encuentra estratégicamente ubicado en la entrada a Gales del Sur, a 12 millas de Cardiff y 30 millas de Bristol. En este enclave urbanístico CAF se ha instalado con una nueva planta para acabado de vehículos ferroviarios y realización de pruebas.

Esta planta, que entrará en funcionamiento en otoño del 2018, cuenta con un terreno de 46.000 m2 ampliable, y con una superficie construida de 15.000 m2 y dará trabajo a una plantilla aproximada de 250 trabajadores.

La instalación cuenta con un transbordador GH Cranes que da servicio a las naves (tanto las de acabado y pruebas como la de almacén) y a las zonas auxiliares (cabina de pintura, arco de estanqueidad y vías de almacenamiento).

Aunque GH fabrica principalmente grúas puente, pórticos y polipastos, dentro de su gama de productos también se desarrollan grúas pluma, carretones y también transbordadores ferroviarios para capacidades entre 60 t. y 150 t., utilizados sobretodo en el manejo de trenes en las labores de mantenimiento. Los transbordadores GH destacan por su rapidez, seguridad y la facilidad de desplazamiento.

En el caso de este transbordador para CAF, su capacidad de carga son 80 t. y tiene unas dimensiones de 25 m. con 2,5 m. adicionales de voladizo a cada lado y plataforma transitable para carretilla.

La inversión de CAF en esta instalación de Newport es superior a 35 M€ y cuenta, además de este transbordador GH, con otros equipos para las labores de producción, como grúas, cabina de pintura y arco de estanqueidad.

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.
