ALE provided the full engineering scope, including the stability checks, lashing and jacking calculations, saddles proposals, transport arrangements and all civil infrastructure works.

The company jacked-up the cargo using four hydraulic 130t jacks and six man lifts from the ground to the suitable height for the 24 axle lines of SPMTs to drive underneath the saddles of the cargo.

The heavy pieces were transported in convoy through the city centre of Atyrau on conventional trailers and SPMTs under police escort. In order to minimise disruption to the citizens, transportation was conducted only on Sundays and outside of peak hours.

During the convoy, ALE utilised 44 axle lines of conventional trailers in a four file 22 configuration.  The trailers were precisely manoeuvred through the city’s narrow streets. On several turns, the trailer’s axles were lifted to enable fly-over curbs with no damage to equipment or infrastructure.

Marek Lysko, ALE’s operations manager, said: “This project was extremely significant for the region. This is the first time for the client that out-of-gauge units with such dimensions have been transported through the streets of Atyrau. This also required the biggest trailer configuration with the utilisation of almost 70 axle lines of various trailers and transport configurations.”
