Simex TF drum cutters as trusted alternative to conventional excavation methods

Shanghai Construction Group (SCG) has always been involved in urban improvement works: infrastructures, construction, industrial plants and underground utilities. Through our importer ATE, the company has tried a Simex TF 850 double-drum cutter head within excavation works for laying underground drainage pipes along Shanghai subway.

Shanghai is a densely populated city which is developing very fast. Many construction companies are looking for new excavation methods as alternative to traditional ones like, for example, the hydraulic hammer which produces high noise level and huge vibrations, to the detriment of the surrounding residents.
The company has shown its appreciation for drum cutter features.

First of all, the productivity, around 20 mc/h. Secondly, the accuracy: working with hydraulic hammers generate high frequency vibrations that may lead to asphalt cracks and roadbed loosening. TF cutter heads guarantee the selective breaking of the material they are processing, with no excessive stress risk. In addition, the particle size of the milled material is suitable to be immediately reused on site and does not require a further volumetric reduction by a second attachment or operating machine. The crushed material produced by conventional excavation systems is extremely coarse and bulky, which leads to high transportation and disposal costs. TF cutter heads allow the operators to reuse the milled material directly on site with significant economic benefits: there is no need to purchase and transport new raw materials, such as sand and stones, for backfilling trenches.
China is a developing country and many cities are experiencing a strong expansion. For this reason, the government's indications on urbanization are becoming increasingly stringent on the need to use cutting-edge techniques and equipment, with a reduced impact both at the environmental level and in terms of noise pollution. Simex, thanks to the collaboration with its official importer ATE, has introduced in the Chinese market the TF drum cutters technology, as trusted alternative or support to traditional excavation methods.
