Abstract: A frame releasably fixable to a ladder for attaching a mast to the ladder, the frame comprising two sub-frames, each sub-frame comprising two legs, each leg including a stud receiving notch and a support bar at one end thereof, the stud receiving notch for limiting rotation of the sub-frame relative to the ladder, with the frame in place on a ladder and the stud receiving notch engaged with a stud provided on the side of the ladder, the support bar for resting on a surface of the ladder, in use, the two sub-frames releasably attachable to one another at the other end thereof to form a socket for receiving the structural mast.

Abstract: A materials handling system (10) comprising a first (60) and second ladder (70) section connectable together to form a longer ladder, a tensioning system (100) attached to each section for tensioning the connected ladder sections, and a trolley (110) arranged to travel along the connected ladder sections, wherein the system includes a cable (158) and pulley for moving the trolley along the connected ladder sections.

Abstract: A bridging system comprising a bridge (10) and a trolley (70), the bridge comprising a bridge deck (40) having at least two pre-formed bridge sections (42), the trolley including a set of wheels (573) with a track width configured such that in use with the trolley located on the bridge deck, at least one wheel contacts one stringer (443A) and at least one other wheel contacts another stringer (443B), the system further including tracking means for maintaining the at least one wheel in contact with the one stringer and for maintaining the at least one other wheel in contact with the other stringer such that the trolley and bridge deck may remain in contact while moving relative to, or with, one another for the launching of the bridge deck over a space to be bridged, the trolley being configured to carry goods and/or personnel over, and along, the bridge deck after the bridge has been positioned over the space to be bridged.
