London is based on a 150-year-old sewage system built for a population less than half its current size.
Like many ancient cities around the world, most of London has a ‘combined’ sewage system, that collects not only the wastewater from sinks, showers and washing machines, but also the runoff of rainwater from roads, canals and sidewalks. Although the sewers remain in excellent condition, they lack the capacity to meet the demands of modern London. As a result, millions of tons of untreated sewage spills flow into the River Thames each year. To improve this sewerage system, the Tideway company is building a 25 km tunnel under the London River that will prevent tens of millions of tons of sewage from contaminating the River Thames every year. The Thames Tideway Tunnel will provide the needed capacity to address the current pollution problem and provide a suitable system for the future. However, by the tunnel, the sustainable drainage systems will also play their part. Although now, it is not viable to separate the sewer system, reducing the amount of rainwater entering the sewers will extend the useful life of the tunnel. This necessary expansion of London’s sewage network, to be completed by 2024, is being developed at 24 construction points in London. These range from Acton in west London to Beckton in the east, and many are located on the river bank in the city centre. For the development of this work, GH Cranes has designed and manufactured different lifting elements, commissioned by a UTE constituted between Ferrovial and Laing O Rourke (FLO, JV):
Two double rail bridge cranes with 55/15 Tn GHK open trolley capacity. With a light of 35m and an elevation height of 72.6m. These cranes are designed to work intensively in M8 workgroups. Both cranes are ready to work in tandem mode or independently. The cabin is suspended from the trolley for greater control over the load.
A gantry crane that has an open trolley of 30/15 Tn capacity that runs over a 26m route and another 3.5m overhang. Tris gantry is used among other things to feed the tunneler with the keystones for the lining of the tunnel walls.

In LGH they manufacture high quality cranes and also give a good post-sale service with a good level of safety and safe systems for operations.
GH has been present in Thailand for more than 20 years through its local partner Peera Laohakarniyom, with whom it has carried out all its activity in the country in a very satisfactory way.
As a result of this collaboration, seven years ago Peera and GH decided to increase their level of collaboration and set up the LGH joint venture, to make complete cranes for the Thai market.
In this new phase, GH is achieving great penetration through key customers within the Thai market that demand the high standards of quality and competitiveness of both Peera and GH.
One of these companies, Sino Thai Engineering and Construction Public Company Limited (STECON), has been a key GH customer in the past and more recently has ordered a total of seven gantry cranes, one of them (160 tonnes) having made a name for itself as the largest gantry crane installed in the country.
To get to know this customer better and find out about the company’s impressions, we have interviewed Senior Engineer Paruehat Gonbang who has been the contact within the company.

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.
