LADDER, ROOF
Issue 1
Application
Provides safe access to most roofs with an apex.
General description
Consists of a 12ft. straight section with a semi-circular hook section at one
end. Fitted to the outer curved surface of the hook section is a pair of 6in.
diameter wheels. Resilient faced pressure pads are provided along the straight
section and at the end of the hook to allow adequate foothold and to distribute
the weight to prevent damage to the surface of the roof. The ladder is wheeled
up the roof into position and then turned over so that the remote end of the
hook rests on the far roof slope and the grip does not rely on the ridged tile.
The ladders are constructed of aluminium alloy.
Weight
28lb.
Capital cost
£25.
Remarks
Presents a problem in carrying on gang vehicles. A prototype is being
constructed with a detachable hook section to overcome this transportation
difficulty.
Issue 2
Application
Provides safe access to most roofs with an apex.
General description
Consists of three straight sections, 3ft., 6ft., and 9ft. long respectively and
a hook section, to simplify transportation and to cater for various lengths of
roof. The sections may be connected together as required by means of stile plugs
and sockets that are locked with "pip-pins".
Three resilient faced bearer pads are provided to allow
adequate foothold and to distribute the weight to prevent damage to roof tiles.
One of these bearer pads is fixed to the hook section, but the other two may be
positioned as desired to suit any particular roof.
The ladder is wheeled up the roof into position and then turned over so that the
remote end of the hook engages on the far roof slope.
The ladders are constructed of aluminium alloy.
Weight
38lb.
Capital cost
£25.
Remarks
A few prototypes have been constructed of magnesium alloy in an attempt to
further reduce weight and are fitted with treads in lieu of rungs. Subject to
successful field trial this new type will supersede the roof ladder described
above.
