Abstract
Abstract An apparatus comprising a work platform movable inside a vessel and associated with a handling robot for handling and laying bricks is presented. The present invention includes at least two hoists placed next to one another, each hoist comprising several telescopic sections. Carriages move along the hoists in order to raise the bricks individually from a depalletizing station located at the foot of the hoist up to platform level. A depalletizing robot, the action of which is coordinated with that of the handling robot, transfers the bricks from a reserve of several brick pallets onto the carriages of the hoist.
