  • Patent number: 11466420
    Abstract: A foundation engineering machine and method for producing a trench in the ground include a substantially vertical mast, a diaphragm wall apparatus displaceably supported in a longitudinal direction of the mast for producing the trench, and a bar-shaped holder, at the lower end of which the diaphragm wall apparatus is mounted and with which the diaphragm wall apparatus is linearly displaceable along the mast. An upper first clamping sledge with a first clamp for releasably clamping the bar-shaped holder and a lower second clamping sledge with a second clamp for releasably clamping the bar-shaped holder are movably supported on the mast. The first clamping sledge and the second clamping sledge are movable relative to each other, and the lower second clamping sledge has a connector for mounting an additional lifting device disposed on the ground, with which a force can be applied in the longitudinal direction onto the second sledge.
