ABSTRACT:
A work cradle comprising a work platform suspended by ropes from a building. Two guide ropes extend downwardly on either side of the platform and are secured to the building. The work platform is attached to the guide ropes by two further ropes which are slidable along the guide ropes by means of releasable hooks. The ropes pass over respective pulleys attached to an extension projecting from the platform in a direction away from the building. A winch is provided for each rope to apply tension to the ropes by means of which the platform may be prevented from swinging away from the building, and/or may be moved to a different lateral position, at a given suspension height.
Also disclosed is a beam clamp which may be used with the above-described work cradle.
