Heightsafe’s Rope Access Dead Weight Trolley Systems provide an adaptable, flexible and cost-effective alternative to fixed suspended abseil access systems such as davit arms. This ensures that the system is suitable for buildings and projects with irregular façade maintenance requirements.
The dead weight trolley is an effective system for enabling rope access cleaning and maintenance on listed buildings as it is portable and does not need to be permanently fixed to the roof. This standalone unit offers a non-destructive alternative to a davit arm system – the installation of which would require the roofs’ structure to be penetrated and the building’s exterior envelope aesthetics to be altered.
The system is particularly effective when a parapet wall features as part of the building’s structure (not including Collective Edge Protection systems). The temporary dead weight trolleys can be adjusted to the height of the wall, ensuring that the top bar is just higher than the copings – 450mm minimum and 1,200mm maximum upstands.
Each component of the system weighs no more than 25kg, meaning it is easy to assemble and manoeuvr to different access points on the roof. It is also ideal for working in confined spaces.
This system has been approved by IRATA in line with the trade association’s International Code of Practice.
