Crane jacking with the Mega Jack 800, Barcelona, Spain

Overview:

ALE has completed the jacking of an STS crane by 6.3m at the TCB terminal in the Port of Barcelona. The manoeuvre was the first of three twin STS cranes to be heightened and was the first time ALE’s latest innovation, the Mega Jack 800, has been used for a crane jacking in Spain.

 

Services Required:

The upper part of the crane was jacked using the jacking points in the modular beams. The distance between the rails of the crane was 30,480mm and the loads lifted in each leg ranged from 302t to 437t, which amounted to a combined total of 1,433t.

The Mega Jack 800 system was used alongside a gantry support measuring 20.5 x 20.6 x 16.5mm installed on four towers with four integrated hydraulic jacks with 620mm stroke (each) and 800t capacity per tower.

The crane jacking was performed in 12 stages and the crane was raised by 560mm at each stage. The crane reached a total height of 6.3m to allow for the 6m leg extensions to be installed.

Resumen:

ALE ha realizado un recrecido de 6m de la primera de las tres grúas gemelas que se encuentran en la terminal de TCB del Puerto de Barcelona.

 

Servicios Requeridos:

La maniobra se ha llevado a cabo con el nuevo sistema Mega Jack 800, formado por cuatro torres de 800t de capacidad unitaria.
