Just a week after we reported on concrete pump trucks pitch-side at Wembley (), we now hear about this recent job at Twickenham, where some of the seating areas in the west stand have been remodelled.
Camfaud was called in by SBS Building Consultants, which was working for the main contractor Ellmer Construction, part of Byrne Group.
Camfaud used a Putzmeister BSF 47-5.16H pump, whose 47-metre boom pump was long enough to reach the area being remodelled but compact enough to be set up between the edge of the pitch and the front of the stand.
Due to the restricted area available for the pump, the vehicle was set up using its one side support (OSS) system. This allowed the pump to set up fully rigged on the work side and partially rigged on the off side with an interlock preventing the boom from slewing outside of the safe work area.聽 Using the OSS system, the outrigger width was reduced from nine metres to less than seven metres.聽
Although the pump has an output capacity of 160m3 per hour, this was not required; only small volumes of concrete were needed and it had to be pumped at a slow speed to allow the SBS concreting team to place and finish the concrete.聽 The pump鈥檚 radio remote control, proportional output valve and end hose shut-off valve allowed the pump operator to work alongside the placing gang, pump at slow speed and minimise the spillage from the end hose when moving the boom.
