Heald’s Synergy Expansion Joint unit consists of a 5400mm barrier creating a free space of 4000mm between the two bollards as part of the Heald Synergy Bollard System.
Heald’s Synergy Expansion Joint unit was designed to provide capacity for bridge expansion, allowing for lateral movement of up to 150mm. The unique design requires no pinning and no excavation into the carriageway. Alternative barrier lengths are available on request.
Designed as an accessory to work alongside the Synergy Bollard System, and for bridges in particular, the bollard system has been IWA-14 crash tested to halt a 7.2 N3C vehicle (18 tonner) travelling at 48 kph (30 mph). Its unique interlocking design provides shared distribution of the load, while patent protected technology offers additional protection by anchoring the bollards into the ground upon impact.
