AH developed by the UK dual-purpose steel rail AH rail repair by the British company Acrow in the 70s of this century developed a mainly for the road, can also be used for assembly of heavy rail repair steel beam. The company has mass-produced Bere Beam since the 1940s and has developed AP beams and other bridge equipment.
