Weightanka devices from Solid Dynamics are portable deadweight roof anchors that can be used when installing a permanent anchor device is not possible. Its central pedestal design reduces movement of the Weightanka in the case of a fall arrest event, making it a stable anchorage point on roofs of up to a 5 degree pitch.
The base layer weights are encased in rubber to ensure Weightanka does not damage or penetrate roof surfaces. The device can be safely used in wet or dry conditions and on a number of roof surface types, including single ply membrane, asphalt, concrete, and steel cladding.
The basic system weighs just 250kgs, and has few loose components, none of which weigh more than 25kgs. This makes it an easy system to move and assemble whenever reliable roof anchors are required.
