Operating on the significant infrastructure project that aims to enhance the traffic flow and safety in Erpe-Mere, the E40 highway was initially planned on being closed from 10pm through to 10am the following morning. Sarens, however, conducted the six lifts three hours ahead of the scheduled reopening time, allowing the highway to be accessible via traffic by 7am the next morning.
Each of the six precast concrete beams lifted by Sarens measured in at 44m in length and weighed approximately 110 tonnes. In order to complete its scope of work, Sarens deployed its Demag AC700-HA configured with a boom length of 35.5m and a counterweight of 140 tonnes, and an LTM 1450-8.1 set up with a 26.6m boom and 134 tonnes of counterweight.

The nine-axle 700-tonne capacity Demag AC700-HA features a 60m main boom that can be extended with different luffing and fly jib configurations. Recently, the crane was upgraded by Tadano to the AC 9.700-1, with the crane still possessing a 60m main boom – the longest for any nine-axle crane – and now featuring a maximum tip height of 147m, a maximum load radius of 110m, as well as a maximum counterweight of 160 tonnes.
The 450-tonne capacity Liebherr LTM 1450-8.1, on the other hand, features a maximum lifting height of 132m and a maximum lifting radius of 103m. A standout feature of the machine is the crane’s ability to carry its complete, seven-section, 85m telescopic boom on public roads while complying with the 12-tonne axle load limit.
Sarens delivered the project for client Jan de Nul as part of a broader initiative to renovate and repair vital transport structures across Belgium’s northern region, Flanders.
