A jacking system for jacking a structure, includes a leg having a longitudinal axis and including first engagement parts along the leg, and a guiding frame displaceable along the leg. The guiding frame includes at least a first, second, third and fourth actuator, the actuators each having a first and second actuator part which in operation can displace with respect to one another along the leg, the first actuator part of the actuators coupled to the guiding frame, the second actuator parts of the actuators each coupled to first engagement parts for engaging and disengaging the first engagement parts of the leg for providing abutment in the longitudinal direction of the leg, the second actuator parts of the actuators displaceable along the leg past one another, and the actuators being arranged in pairs opposite one another with respect to a longitudinal plane of the leg.
