A scaffold (10) comprises ledgers (L1-L3), transoms (T1-T6) and standards (S1-S5), where the transoms are spaced apart by a distance 'd', preferably 1200mm, an entrance (18, 20) of width 'd' and a door hingedly mounted to close the entrance and open into the workspace defined by the scaffolding. Preferably the door is biased, by a spring to a closed position and its movement limited to around 90 degrees rotation when it is opened. When the door (34) is in the floor (16) of the workspace the door may be bounded by a frame (30) secured to adjacent transoms which prevents the door from opening downwards. When the entrance is in the sidewall, a ladder (40, Figure 4) may cover part of the distance 'd' of the entrance and the door (46, Figure 4) close the space up to the ladder. |
