LOAD-ENGAGING ELEMENTS OR DEVICES FOR CRANES, CAPSTANS, WINCHES, OR TACKLES ({specially adapted for lifting invalids A61G7/10;} rope, cable, or chain winding mechanisms, braking or detent devices therefor B66D; specially adapted for nuclear reactors G21) - E02F: DREDGING; SOIL-SHIFTING (winning peat E21C49/00) ## Abstract Mobile plant stabilizer (2) including an extendible leg (4) and a load distributing foot (12) connected to the extendible leg (4), wherein the foot (12) includes a primary part (14) and an extension part (18) connected to the primary part (14) by a hinge (20) enabling the extension part (18) to rotate relative to the primary part (14) to and from a deployed position in which the extension part (18) extends laterally outwardly from the primary part (14). ## Claims ### Claim 1 A mobile plant stabiliser including an extendible leg and a load distributing foot connected to the extendible leg, wherein the foot includes a primary part and an extension part connected to the primary part by a hinge enabling the extension part to rotate relative to the primary part to and from a deployed position in which the extension part extends laterally outwardly from the primary part, the stabiliser further including a locking mechanism for locking the or each extension part in its deployed position, and wherein the locking mechanism includes a locking member extending radially outwardly from the leg, the foot being rotatable relative to the locking member about a longitudinal axis of the leg such that the or each extension part becomes engaged by the locking member to lock it in its deployed position. ### Claim 2 (depends on 1) The stabiliser of claim 1 wherein, in its deployed position, a downwardly facing sole portion of the extension part forms an extension of a downwardly facing sole portion of the primary part. ### Claim 3 (depends on 1) The stabiliser of claim 1 wherein the foot includes two extension parts arranged on opposite sides of the primary part and each connected to the primary part by a respective hinge. ### Claim 4 (depends on 1) The stabiliser of claim 1 including a retention mechanism that holds the or each extension part in a non-deployed position. ### Claim 5 (depends on 4) The stabiliser of claim 4 wherein the retention mechanism is configured to hold the or each extension part in its non-deployed position when the leg is retracted. ### Claim 6 (depends on 4) The stabiliser of claim 4 wherein the retention mechanism includes at least one retention member and wherein the or each extension part is engageable with one said retention member when the leg is in a retracted state to hold the extension part in its non-deployed position. ### Claim 7 (depends on 6) The stabiliser of claim 6 wherein the or each extension part includes an abutment arranged such that retraction of the leg brings the abutment into contact with one said retention member thereby urging the extension part into its non-deployed position. ### Claim 8 (depends on 4) The stabiliser of claim 4 wherein the retention mechanism includes retention members which define entrapment regions configured to hold the extension parts in their stowed positions when the leg is in a retracted state. ### Claim 9 (depends on 8) The stabiliser of claim 8 configured such that extension of the leg disengages the or each extension part from its associated retention member. ### Claim 10 (depends on 9) The stabiliser of claim 9 configured such that initial extension of the leg disengages an outermost portion of each extension part from the respective retention member. ### Claim 11 (depends on 1) The stabiliser of claim 1 including at least one proximity sensor for sensing a predetermined stage in a deployment sequence of the stabiliser. ### Claim 12 (depends on 11) The stabiliser of claim 11 including a sensor provided to sense when a required rotation of the foot relative to the locking member has occurred. ### Claim 13 (depends on 11) The stabiliser of claim 11 including a proximity sensor arranged to provide a signal to confirm that a respective extension part is in a fully stowed position. ### Claim 14 (depends on 1) The stabiliser of claim 1 further including a stop member which limits rotation of the foot relative to the leg. ### Claim 15 (depends on 1) The stabiliser of claim 1 configured such that rotation of the foot is possible so that a sole of the foot is not perpendicular to the longitudinal or extension axis of the leg.
