Abstract

The towable trolley ( 1 ) for the transport of equipment ( 2, 3, 4, 5, 6 ) intended to be mounted on telescopic loaders or the like, comprising a support platform ( 10 ), movement members ( 7 ), for example wheels or the like, and one or more attachment units ( 8, 11, 12, 13, 14, 15, 16, 17, 18, 20 ), mounted on said platform ( 10 ) and adapted to stably secure at least one equipment to the platform ( 10 ) itself.

First claim

The invention claimed is:

1. A towable trolley ( 1 ) for the transport of equipment ( 2 , 3 , 4 , 5 , 6 ) intended to be mounted on a telescopic loader or the like, comprising a support platform ( 10 ) and movement members ( 7 ), for example wheels or the like, characterized by comprising one or more attachment units ( 8 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 20 ), mounted on said support platform ( 10 ) and adapted to stably secure at least one equipment to the platform ( 10 ) itself, in which at least one attachment unit comprises at least one positioning element ( 11 , 12 , 13 , 14 , 20 ), suitable for being mechanically engaged with an equipment, and at least a coupling device ( 15 , 16 , 17 , 18 ) able to allow coupling and release of the equipment which is engaged with said positioning element ( 11 , 12 , 13 , 14 , 20 ), wherein said positioning element ( 12 , 13 , 20 ) comprises a horizontal and/or cantilevered retaining portion.

2. The trolley ( 1 ) according to claim 1 , in which one or more of said attachment units are adapted to secure to the support platform ( 10 ) at least one of the following equipment: a fork ( 4 ), an arm for fixed hook ( 3 ), a load basket ( 2 ), a winch ( 5 ), an horizontal beam ( 6 ) for cranes.

3. The trolley ( 1 ) according to claim 1 , in which at least one attachment unit is suitable for attachment of one or more hollow tubular elements ( 21 , 51 ) thereto, which hollow tubular elements ( 21 , 51 ) exhibit a quadrangular section and are provided on an equipment ( 2 , 5 ).

4. The trolley ( 1 ) according to claim 1 in which at least one attachment unit is adapted to be attached to at least one tubular element ( 31 , 61 ) exhibiting a substantially circular cross section, provided on an equipment ( 3 , 6 ).

5. The trolley ( 1 ) according to claim 1 , in which one or more attachment units are adapted to automatically engage one or more equipment ( 2 , 3 , 4 , 5 , 6 ).

6. The trolley ( 1 ) according to claim 5 ,
wherein said coupling device ( 15 , 16 , 17 ) comprises:
at least one movable element ( 151 , 161 , 171 ); and
at least one elastic contrast element acting on said movable element ( 151 , 161 , 171 ).

7. The trolley ( 1 ) according to claim 6 , wherein said movable element is provided with a rotatable contact member ( 152 , 162 , 171 ).

8. The trolley ( 1 ) according to claim 1 , wherein said positioning element ( 12 , 13 ) comprises a retaining portion which inferiorly defines an undercut ( 19 ).

9. The trolley ( 1 ) according to claim 7 , comprising at least one attachment unit having at least one coupling device ( 15 , 16 , 17 ), the movable element ( 151 , 161 , 171 ) of which is suitable to be displaced between a retracted position and an extended position.

10. The trolley ( 1 ) according to claim 7 , comprising at least one attachment unit provided with at least one coupling device ( 15 , 16 ) having a movable element ( 151 , 161 ), which exhibits a projecting arm provided with a contact roller ( 152 , 162 ).

11. The trolley ( 1 ) according to claim 7 , comprising at least one attachment unit provided with at least one coupling device ( 17 ), provided with a movable element comprising at least a sphere ( 171 ).

12. The trolley ( 1 ) according to claim 1 , wherein the coupling device of at least one attachment unit comprises at least an anchoring pin ( 18 ) provided with a cotter pin and suitable for the manual anchoring of at least one equipment.

13. A towable trolley ( 1 ) for the transport of equipment ( 2 , 3 , 4 , 5 , 6 ) intended to be mounted on a telescopic loader or the like, comprising a support platform ( 10 ) and movement members ( 7 ), for example wheels or the like, characterized by comprising one or more attachment units ( 8 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 20 ), mounted on said support platform ( 10 ) and adapted to stably secure at least one equipment to the platform ( 10 ) itself, in which at least one attachment unit comprises at least one positioning element ( 11 , 12 , 13 , 14 , 20 ), suitable for being mechanically engaged with an equipment, and at least a coupling device ( 15 , 16 , 17 , 18 ) able to allow coupling and release of the equipment which is engaged with said positioning element ( 11 , 12 , 13 , 14 , 20 ), wherein at least one attachment unit comprises a housing structure ( 8 ) provided with two side walls ( 81 , 82 ) between which an equipment ( 3 , 4 , 6 ) can be inserted, said side walls ( 81 , 82 ) being adapted to cooperate functionally with at least one coupling device ( 17 , 18 ) in order to anchor the inserted equipment to the platform ( 10 ).

14. The trolley ( 1 ) according to claim 11 , wherein at least one attachment unit comprises a housing structure ( 8 ) provided with two side walls ( 81 , 82 ) between which an equipment ( 3 , 4 , 6 ) can be inserted, said side walls ( 81 , 82 ) being adapted to cooperate functionally with at least one coupling device ( 17 , 18 ) in order to anchor the inserted equipment to the platform ( 10 ), and wherein each coupling device ( 17 ) is mounted on a respective side wall ( 81 , 82 ) with the respective spheres ( 171 ) which project inwardly the structure ( 8 ).
