Abstract: A facade scaffold includes an inner pole, an outer pole and a scaffold cross-bar between the inner and outer poles. A hollow pole portion of the inner pole has a first receiving through-aperture for a coupling for the attachment of a scaffold holder. A maximum distance between the first receiving through-aperture and a top side of the scaffold cross-bar is no more than 300 mm. The first receiving through-aperture is arranged below the top side of the scaffold cross-bar, or is realized above the top side of the scaffold cross-bar as a first elongated hole. The longitudinal axis of the first elongated hole is aligned parallel to the pole longitudinal axis of the hollow pole portion. The invention simplifies and accelerates the operation of assembling a scaffold holder on a scaffold and for a two-pole scaffold holder allows a passage height under the scaffold holder to be increased.

Abstract: A descender (10) comprises a rear or base plate (20), a front plate (22) which is fixedly mounted to the base plate, generally parallel to and spaced from the base plate and an arm (30) which is pivotally mounted to the base plate and/or the front plate for movement between the two plates. The arm (30) defines a generally curved channel (38) through which a rope (14) may pass. The channel is defined between a sheave (34) and a wall (37) of the arm and defines an entrance (38a) and an exit (38b) for the rope. The sheave (34) is pivotable about an axis, the sheave being lightly biased towards a first or rest position. Pivoting of the sheave about the axis in a first direction, away from the rest position, causes an increase in the friction applied to the rope passing through the channel, typically by causing the exit of the channel to narrow.
