Abstract
Abstract This invention relates to a method of handling the driver's cab of a public works machine, said cab being mounted to pivot on the frame (turret) of the machine and this machine comprising a working attachment, mounted on said frame, whose form may undergo a modification. The pivoting axis of the cab is substantially perpendicular to the plane of deformation of the working attachment, a zone of the cab distinct from the one where the axis is located is coupled, via a sling, to the working attachment and the deformation of the working attachment is controlled so as to displace said coupling zone thus pivoting the cab as desired. One application of the present invention is the realization of a high power hydraulic shovel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A method of handling the driver's cab of a public works machine, said cab being mounted to pivot on the frame of the machine and said machine comprising a working attachment mounted on said frame whose form may undergo a modification, wherein the pivoting axis of the cab is substantially perpendicular to the plane of deformation of the working attachment, a zone of the cab distinct from the zone where the pivoting axis is located is coupled to the working attachment and the deformation of the working attachment is controlled so as to displace said coupling zone, thus pivoting the cab as desired.
Claim 2
Independent Claim
103 words
A method of handling the driver's cab of a public works machine, said cab being mounted to pivot on the frame of the machine and said machine comprising a working attachment mounted on said frame whose form may undergo a modification, wherein the pivoting axis of the cab is substantially perpendicular to the plane of deformation of the working attachment, a zone of the cab distinct from the zone where the pivoting axis is located is coupled to the working attachment and the deformation of the working attachment is controlled so as to displace said coupling zone, thus pivoting the cab as desired.
Claim 3
Dependent Claim
96 words
A public works machine comprising a frame, an arm mounted to pivot with respect to the frame about a first axis and supporting the working tool, a movable cab, pivot means connecting said cab to said frame for enabling said cab to pivot with respect to the frame about a second axis substantially parallel to the first axis, fastener means connected to the cab at a location spaced from the second axis and tie means connecting said fastener means to said arm for effecting pivotal movement of said cab by pivoting of said arm as desired.
Claim 4
Dependent Claim
96 words
A public works machine comprising a frame, an arm mounted to pivot with respect to the frame about a first axis and supporting the working tool, a movable cab, pivot means connecting said cab to said frame for enabling said cab to pivot with respect to the frame about a second axis substantially parallel to the first axis, fastener means connected to the cab at a location spaced from the second axis and tie means connecting said fastener means to said arm for effecting pivotal movement of said cab by pivoting of said arm as desired.
Claim 5
Dependent Claim
55 words
A public works machine as claimed in claim 2, wherein the tie comprises a flexible connection means and additionally including a member for guiding said connection means mounted to rotate with respect to a frame and cooperate with the connection means in a position disposed substantially near the vertical plane containing the second pivoting axis.
Claim 6
Dependent Claim
25 words
A public works machine as claimed in claim 2 additionally including members for maintaining the cab in its two extreme configurations, viz, pivoted and non-pivoted.
Claim 7
Dependent Claim
25 words
A public works machine as claimed in claim 2 additionally including members for maintaining the cab in its two extreme configuration, viz, pivoted and non-pivoted.
Claim 8
Dependent Claim
24 words
A public works machine as claimed in claim 3, additionally including stop means fixed to the frame for limiting the pivoting of the cab.
Claim 9
Dependent Claim
25 words
A public works machine as claimed in claim 3, additionally including members for maintaining the cab in its two extreme configurations, viz, pivoted and non-pivoted.
Claim 10
Dependent Claim
25 words
A public works machine as claimed in claim 4 additionally including members for maintaining the cab in its two extreme configurations, viz, pivoted and non-pivoted.
