A versatile construction hoist system comprises a hoist trolley (2) having a first pair (16, 18) of connection members, and a work platform (32) having a second pair (38, 40) of connection members. The work platform is releasably connectable to the trolley through interconnection of the first and second pairs of connection members with the work platform in a horizontal position in which the work platform floor is situated at the first level (55) relative the trolley. A transport platform (60), which has a third pair (74, 76) of connection members, is releasably connectable to the trolley (2) through interconnection of the first (16, 18) and third pairs (74, 76) of connection members with the transport platform in a horizontal position in which its floor (62) is situated at a second level (80) relative the trolley, said second level being below said first level. An adapter (66) enables use of standard transport platform elements.
