Abstract
Abstract Apparatus for stabilizing a civil engineering machine mounted on an uneven surface. Two props are pivotally connected to the chassis of the machine and are arranged for movement relative to each other and to the chassis by jack means connecting the props. Further jack means connecting at least one of the props to the chassis serve to lock the pivotal connection between each such prop and the chassis thereby locking the props relative to each other and to the chassis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
In a civil engineering machine having a chassis and stabilizing means comprising at least one pair of props and pivotal connections between each prop of said pair and the chassis, actuating linkage means connecting said pair of props and extending between points on said props spaced from said pivotal connections between each prop and said chassis and including jack means comprising a portion of the connection between said props operable upon actuation for simultaneously pivoting said props and means for locking said actuating linkage means for preventing movement of said actuating linkage means with respect to said chassis to hold said props in fixed positions with respect to said chassis.
Claim 2
Dependent Claim
110 words
In a civil engineering machine having a chassis and stabilizing means comprising at least one pair of props and pivotal connections between each prop of said pair and the chassis, actuating linkage means connecting said pair of props and extending between points on said props spaced from said pivotal connections between each prop and said chassis and including jack means comprising a portion of the connection between said props operable upon actuation for simultaneously pivoting said props and means for locking said actuating linkage means for preventing movement of said actuating linkage means with respect to said chassis to hold said props in fixed positions with respect to said chassis.
Claim 3
Dependent Claim
47 words
A civil engineering machine according to claim 15 wherein said actuating linkage means include a first hydraulic jack secured between said pair of props, an element rigidly connected to the chassis, and a second jack secured between said element and one of the props of said pair.
Claim 4
Dependent Claim
41 words
A civil engineering machine according to claim 2 including a fixed axle, an axle mounted for rocking movement relative to the chassis in a plane extending laterally of the chassis, and a pair of conventional props disposed near the fixed axle.
Claim 5
Dependent Claim
23 words
A civil engineering machine according to claim 3, wherein said one pair of props is disposed near said axle mounted for rocking movement.
Claim 6
Dependent Claim
93 words
A civil engineering machine having a chassis and stabilizing means comprising at least one pair of props and pivotal connections between each prop of said pair of props and the chassis, the improvement comprising means connecting said pair of props and means for locking at least one of said pivotal connections wherein said means connecting said pair of props includes an arm pivotally connected to the chassis, a first pair of jacks respectively secured between said pair of props and said arm, and a hydraulic jack secured between said arm and the chassis.
Claim 7
Dependent Claim
93 words
A civil engineering machine having a chassis and stabilizing means comprising at least one pair of props and pivotal connections between each prop of said pair of props and the chassis, the improvement comprising means connecting said pair of props and means for locking at least one of said pivotal connections wherein said means connecting said pair of props includes an arm pivotally connected to the chassis, a first pair of jacks respectively secured between said pair of props and said arm, and a hydraulic jack secured between said arm and the chassis.
Claim 8
Dependent Claim
41 words
A civil engineering machine according to claim 5, including a fixed axle, an axle mounted for rocking movement relative to the chassis in a plane extending laterally of the chassis, and a pair of conventional props disposed near the fixed axle.
Claim 9
Dependent Claim
23 words
A civil engineering machine according to claim 6, wherein said one pair of props is disposed near said axle mounted for rocking movement.
Claim 10
Dependent Claim
72 words
A civil engineering machine according to claim 1, wherein said actuating linkage means includes two arms pivotally connected to the chassis, a first pair of jacks secured respectively between one prop of said pair of props and one of said arms and between the other prop of said pair of props and the other of said arms and a pair of hydraulic jacks secured respectively between said two arms and the chassis.
Claim 11
Dependent Claim
41 words
A civil engineering machine according to claim 8, including a fixed axle, an axle mounted for rocking movement relative to the chassis in a plane extending laterally of the chassis, and a pair of conventional props disposed near the fixed axle.
Claim 12
Dependent Claim
23 words
A civil engineering machine according to claim 9, wherein said one pair of props is disposed near said axle mounted for rocking movement.
