Abstract
A device for ventilating a burning building that includes, a chassis; and a cutting assembly, mounted on the chassis. The cutting assembly is adapted to cut a ventilation hole in a roof or wall member of a building either autonomously or under remote control by an operator to allow smoke and/or hot gases to escape from the roof space.
Claims1
A method of ventilating a burning building comprising:
- positioning a device on a roof of a burning building for ventilating the burning building, the device comprising:
- a chassis;
- and
- a cutting assembly mounted on the chassis wherein the cutting assembly comprises:
- a platform that rotates so as to define a circle of rotation;
- a first chain saw mounted on the platform at a first side of the platform and mounted for first rotational displacement, as a whole, about a first axis that is substantially perpendicular to the roof so that the first chain saw rotates along the circle of rotation with respect to the chassis, and for first rotational movement of the first chain saw, as a whole, with respect to the platform about a first axis of rotation not related to rotation of the platform;
- a second chain saw mounted on the platform at a second side of the platform opposite to the first side of the platform and mounted for second rotational displacement, as a whole, about the first axis that is substantially perpendicular to the roof so that the second chain saw rotates along the circle of rotation with respect to the chassis, and for second rotational movement of the second chain saw, as a whole, with respect to the platform about a second axis of rotation not related to rotation of the platform;
- and
- the method further comprising causing the first chain saw and the second chain saw to form a hole in the roof of the burning building.
