A lifting cradle for use with a modular building system of the type in which pre-fabricated modules constructed off-site are inserted into openings in a support frame constructed on-site to produce a building according to a user's requirements. The lifting cradle has a central loading platform and two safety cages arranged on opposite sides of the platform for operatives to view and/or control installation of the module in the opening. The lifting cradle is temporarily attached to the building during installation of the module and a counterbalance mechanism is provided to maintain stability of the lifting cradle during installation. The lifting cradle may also be employed when removing modules from the building.
