- 10 - ABSTRACT. For the assembly of shaft equipment, an erection scaffolding with a first working platform (4), with a second working platform (5), with a third working platform (6) and with a fourth working platform (7) is moved in vertical direction. The first working platform (4) is arranged at the lower end and the second working platform (5) is arranged at the upper end of a cage support frame (8), which is provided for the reception of the lift cage after the erection operations. Above the support frame (8), the erection scaffolding continues with the third working platform (6) and ends with the fourth working platform (7). Serving as suspension of the support frame (8) is a suspension tube (9), a lower deflecting roller (10) arranged at the upper end of the suspension tube (9) and an upper deflecting roller (12) arranged at the shaft support (11), which rollers are connected by way of a cable (13), suspended 3:1, of a hoist tackle (14) anchored at the support frame (8). The shaft support (11) carries a speed limiter (17) as well as a tackle with cable drum (18) which serves for the transport of material. In that case, a tackle cable (20) is led off to the working point by way of a jib crane (21) arranged at the upper end of the suspension tube (9). The working platforms (4; 5; 6; 7), which are accessible by way of ladders (22) and trap doors, are secured by railings (24) and hinged barriers. (Figure 1)
