1. Introduction The Custers® mobile scaffold tower is part of a wide range of aluminium scaffold variants. The Custers® mobile scaffold tower, if assembled according to this manual, complies with the actual standard EN1004-1:2020. Custers Hydraulica B.V. has assessment documentation as well as certificates to proof the conformity of the Custers® mobile scaffold system to the actual standards.
4. Marking of mobile scaffold tower components Each aluminium / plastic / wooden component from the mobile scaffold tower is provided with the Custers’ company name and a two-digit code corresponding to the year of production. 8-rung frames are always provided with a compulsory waterproof label with...

The mobile scaffold tower must be erected flat with a maximum inclination of 1% (a maximum of 1 cm inclination over a length of 1 metre); check this with a spirit level; correction is possible by tightening the spindle nuts of the casters. The casters must always be in locked position, except for relocating the scaffold.

Frame security pin Horizontal braces/guardrails must preferably be positioned on the uprights in such a way that the openings of the claws point outwards.
Page 8
There must always be at least 1 platform with hatch on the working level; the working level must be fitted with: guardrail, knee railing and toe boards all around. There must always be at least one platform with a hatch on the resting level. The resting level must be fitted all around with guardrails and knee railings and must be installed every 2 metres.
6.4. Lifting up components Lifting up components onto higher areas should be done by passing the components from platform to platform. Parts can also be lifted upwards with a sturdy rope. Use a proper knot, loop or hook to secure the components. Hoisting equipment may not be attached to the scaffold.

It is not allowed to make bridges between a mobile scaffold tower, unless specifically calculated applications are used. The maximum workload is 200 kg/m (scaffolding class 3); only one level of maximum load per scaffolding may be used. The maximum uniformly distributed load on a working platform is 275 It is prohibited to jump on the platforms;...

Take care that ladder platforms always have to be applied above a non-ladder platform or the ladder should be supported by the fixed part of the ladder platform underneath . The hatches of these platforms always have to be closed after use of the ladder. The design is as such, that the hatches close automatically.

It is prohibited to work on the scaffolding if the wind force is greater than 6 Beaufort (large branches move, umbrellas fold, the wind speed is 11 - 14 m/s = ± 45 km/h). If the expected wind force is greater than 6 Beaufort the freestanding mobile scaffold tower must be either disassembled, or relocated to a wind-free zone, or be anchored.
Mobile access and working towers are not designed to be sheeted: it is prohibited to attach wind-catching surfaces such as billboards or tarpaulins to freestanding scaffolds. The scaffold must not be exposed to aggressive liquids or gases. Mobile access and working towers in accordance with EN1004-1 are not designed to be used as a means of edge protection.
Reduce the height to 6,3m platform height maximum The maximal permitted slope is 1% (1% = a maximum of 1 cm inclination measured per 1 metre) In the event of wind forces larger than 4 Beaufort the scaffold may no longer be relocated (4 Beaufort: dust, sand and paper will be blown up, small branches will be torn off;...
