Brenchley’s sucker punch

Digger Blogger | 13:53, Fri July 26 2013

While we like our diggers round these parts, we do recognise that digging is not the only way to excavate. You can suck too, as Brenchley Civil Engineering has discovered.

Brenchley is the first company in the UK to take delivery of the new TT-UK/RSP compact 7.5-tonne City Sucker.

The Portsmouth-based contractor has a street lighting replacement contract for Southern Electric in Hampshire and West Sussex. It has been using a number of larger suction excavators over the past couple of years on this assignment, because digging down on live cables is rather dangerous. Brenchley’s risk assessment calculated that by using suction excavation, their strike rate fell from one in every 142 mains/disconnection holes dug by traditional means (hand or small tools) to one in 546 holes using suction excavation. 

However, the big sucker machines were too big for some areas. For in town and around housing estates, they needed something more compact and manoeuvrable. TT-UK’s City Sucker was arranged on site in Portsmouth and all attending quickly appreciated the efficiency and suction power of the City Sucker which surpassed anything previously seen. Most of all, due to its size the City Sucker can manoeuvre onto many restrictive job sites which larger Suction Excavators could not attempt, thus greatly improving productivity

TT-UK is a trenchless technology equipment specialist and is part of the German group Tracto-Technik. The suction excavators are produced in collaboration with another German firm, Reschwitzer Saugbagger Produktions (RSP).

Mounted on a 2m-wide wide Mitsubishi Fusso chassis, the City Sucker has a single hydraulically driven high performance fan with a maximum capacity of 11,300m3/hr. The hydraulically driven on-board compressor delivers 2.2m3/min at 7 bar, enabling automatic cleaning of the fine filters and operation of pneumatic tools.

The power assisted suction hose has a maximum reach of 3.55m with the option to extend and rotates 180o. Holding capacity of the material container is 1.1m3, material can be discharged directly in to Dumpy bags using the City Suckers unique holder, in to skips or taken off site.

As with all TT-UK/RSP suction excavators, design and options can be tailored to suit particular job applications.
