Abstract
The arm with two or more hooks 1 comprises: a supporting beam 1) designed to be connected to an operating arm 20 of a telehandler 2 or another self-propelled operating machine and a plurality of hooks 11, 12, 13, distributed along the beam 10, each designed for supporting a respective load. One or more hooks 11, 12, 13 are connected to a load sensor 31, 32, 33.
Claims20
A coupling system comprising an arm (1) comprising a supporting beam (10) designed to be connected to an operating arm (20) of a telehandler (2) or another self-propelled operating machine, the arm comprising a plurality of hooks (11, 12, 13), distributed along said beam (10), each designed for supporting a respective load, characterised in that one or more of the hooks (11, 12, 13) is connected to a load sensor (31, 32, 33) designed to produce a load signal as a function of the weight of the load supported by the respective hook, the load sensors are connected to an electronic processing unit (4) comprising a threshold module (42) configured for checking whether the load carried by the one or more of the hooks (11, 12, 13) exceeds or not a respective risk threshold as a function of the maximum weight value which they are designed to support.
A method for using an arm with several hooks (1) mounted on or to be mounted on an operating arm (20) of a telehandler (2), comprising the following steps:
- suspending one or more loads from one or more hooks (11, 12, 13) of said arm (1);
- detecting the weight of the suspended load or loads;
- checking for one or more hooks (11, 12, 13) whether the load carried by them exceeds or not a respective risk threshold as a function of the maximum weight value which they are designed to support.
