摘要:
A first front pair (6A) and a second rear pair (6P) of stabilizer devices are associated to the frame (3) of an operating machine (M), to define, in operative position, a resting base, whose length (X) is equal to the longitudinal distance between the same pairs (6A, 6P) and whose width (Y) is equal to the transversal distance between the resting feet of each of the latter. Each of the above mentioned stabilizer devices (161, 162, 261, 262, 361, 362) includes at least a first and a second module (10, 11 ), interconnected with each other, one of which is provided with linear elongation means (12) and the other is provided with compass elongation means (13), with said linear elongation means (12) and compass elongation means (13) being aimed at being operated in phase relation to define a retracted inactive position (R), in which the corresponding resting foot (19, 25) is raised from the ground and the bulk of said stabilizer device (161, 162, 261, 262, 361, 362) is within the above mentioned machine (M) maximum size limits, and a withdrawn operation position (L), in which said resting foot (19, 25) contacts the ground, at a predetermined distance from the longitudinal midline, such that in this resting base the width (Y) distance is at least near to that of the relative length (X).

The aerial work platform C1, C2 is aimed at being associated to a self-moving operating machine and includes: a fixed central body (1 ), rectangular in plan view, provided with two guard sides (2), located at its long sides (LA) and a central platform (3), situated at the bottom; at least one extension module (10), hinged to said central body (1 ) at one of its smaller sides (LB), consisting of a three side structure (21 ), (22), (23), that defines, together with said smaller side (LB), an articulated parallelogram on a horizontal plane, aimed at assuming two configurations, respectively, flattened rest configuration (X), in which said three sides (21), (22), (23) are folded and placed against said fixed central body (1 ), and an open working one (V), in which the same three sides (21 ), (22), (23) are arranged at an angle one to another to define a side body (20), set beside and aligned with said fixed central body (1 ). A side platform (30), positioned in the side body (20), is beside and aligned with said central platform (3). Locking means (40), aimed at stabilizing said open work configuration (V) of said extension module (10), are provided between the side platform (30) and said sides (21 ), (22), (23) of the structure.
摘要:
A self-moving operating machine with an integrated lateral movement and leveling device, including a chassis having a front part and a rear part, to which a fore axle and a rear axle, both provided with wheels, are constrained, respectively, and including an operating arm having one of its ends constrained to the rear part. The front part and the rear part are articulated to each other by a spherical coupling including two linear actuators, consisting of hydraulic cylinders aimed at operating in mostly vertical directions. A third actuator is rod-wise connected to the front and rear parts, and is aimed at operating according to mostly horizontal directions. The actuators are operated independently. There are provided means designed to measure loads weighing on at least one of the two wheels and to control locking of the rear axle to the rear part upon reaching predetermined limits.

1) A self-moving operating machine with an axle having variable wheel gap, includes a chassis (1) to which a first axle (2) and a second axle (3) are bound respectively, and by which an operating arm (4) is supported, which is hinged with its base to the chassis (1) and carries a tool (5) at its free end. The first axle (2) and the second axle (3) are parallel to each other and provided with a pair of wheels (12) and with a pair of wheels (13) respectively. The first axle (2) has a length that varies upon command and includes at least two half-axles (2a, 2b) which are co-aligned and coupled to each other in axially sliding way. At least one of the half-axles (2a, 2b) is coupled in axially sliding way in a seat (10) made in a body (11) integral with the chassis (1) along a direction parallel to that of relative axial sliding between the two half-axles (2a, 2b). An actuator (6) is provided for acting, upon command, between said body (11) and that of said two half-axles (2a, 2b) which is not coupled to the seat (10), in a direction parallel to that of relative axial sliding between the two half-axles (2a, 2b).
摘要:
Stabilizer device for an operating machine, having a chassis with a pair of stabilizer means associated to one of two opposite ends thereof. They include two stabilizer arms constrained to be symmetric with respect to a vertical middle plane and equipped with feet for resting on the ground. Each stabilizer arm includes a first, straight segment bound with one first end to the chassis and one second segment hinged to the second end of the first segment. The first and second segments are aimed at being mutually positioned in a retracted position (R) in which the encumbrance of said stabilizer arm remains within the operating machine maximum size limits, and an extended, in-operation position (L), in which the related resting foot is in contact with the ground. The axes of both first segments of said pair are included in the same plane, that is perpendicular to the middle plane.
摘要:
The quick connection (1 ) allows fastening a tool (X1 ), (X2) to the lifter arm (S) of an operating machine (M) and includes first and second joining means (10), (20), associated respectively to said lifter arm (S) and said tool (X1), (X2), aimed at being reciprocally engaged. The first joining means (10) includes a swivel head (13) that swivels between a raised position (A) and a lowered one (B), and a first gudgeon (15); the second joining means (20) include a shaped body (21) that defines a calibrated inlet opening (25) and support means (22). The swivel head (13), in raised position (A), enters the shaped body (21 ) through the opening (25), then it rotates to its lowered position (B), thus bringing the first gudgeon (15) in engagement with said support means (22). The shaped body (21 ) includes a stop (24) aimed at striking a winglet (18) of the swivel head (13) and at preventing the latter from going out in any succession of movements which are not inversely equal to those carried out for the introduction.
