Abstract

Loader The invention describes a loader (10). The loader (10) comprises a loader boom (12) and a tool carrier (26) or a tool arranged on the loader boom (12), wherein the tool carrier (26) or the tool is connected at a first pivot point (42, 44) to the loader boom (12) and at a second pivot point (46, 48) to a pivot linkage (24) , wherein the pivot linkage (24) comprises a first and a second link (30, 32, 34, 36) which are pivotably connected to one - another at a first link point (38, 40), and wherein the first link (30, 32) is pivotably connected at a second link point (54, 56) to the loader boom (12) , and the second link (34, 36) is pivotably connected at a second link point (50, 52) at the second pivot point (46, 48) to the tool carrier (26) or to the tool, and furthermore a sensor (58) is provided by means of which a pivot angle between the tool carrier (26) or tool and loader boom (12) can be detected. To protect the sensor in as effective a manner as possible, it is proposed that the sensor (58) is positioned in a cavity (76) on the loader (10), and an actuating device (60) is provided which is connected to the sensor (58) and which extends in the cavity and which is connected to a pivot pin, arranged at the second link point (54) , of the first link (30, 32) , wherein the pivot pin is connected rotationally conjointly to the first link (30, 32) .
