Loader

Abstract

The disclosure describes a loader having a loader boom and a tool carrier or a tool arranged on the loader boom. The tool carrier or the tool is connected at a first pivot point to the loader boom and at a second pivot point to a pivot linkage. The pivot linkage has first and second links which are pivotably connected to one another at a first link point. The first link is pivotably connected at a second link point to the loader boom. The second link is pivotably connected at a second link point at the second pivot point to the tool carrier or to the tool. A sensor is provided by means of which a pivot angle between the tool carrier or tool and loader boom can be detected. To protect the sensor in as effective a manner as possible, the sensor is positioned in a cavity on the loader. An actuating device is provided for the sensor, which extends partially through an opening formed on the cavity and connects the sensor to the pivot linkage.

What is claimed is: 
     
         1 . A loader having a loader boom and a tool carrier or tool arranged on the loader boom, wherein the tool carrier or the tool is connected at a first pivot point to the loader boom and at a second pivot point to a pivot linkage, wherein the pivot linkage has a first link and a second link which are pivotably connected to one another at a first link point, and wherein the first link is pivotably connected at a second link point to the loader boom, and the second link is pivotably connected at a second link point at the second pivot point to the tool carrier or to the tool, and wherein a sensor is provided to detected a pivot angle between the tool carrier or tool and loader boom, wherein the sensor is positioned in a cavity on the loader, and an actuating device is provided for the sensor, wherein the actuating device extends partially through an opening formed on the cavity and connects the sensor to the pivot linkage. 
     
     
         2 . The loader according to  claim 1 , wherein the cavity is formed in the loader boom. 
     
     
         3 . The loader according to  claim 1 , wherein the actuating device has a rotary axle which is connected to the sensor, a rotary lever and a control arm, wherein the rotary lever is connected rotationally conjointly to the rotary axle and the control arm pivotably connects the rotary lever to the pivot linkage. 
     
     
         4 . The loader according to  claim 3 , wherein the control arm connects the rotary lever to the first link of the pivot linkage. 
     
     
         5 . The loader according to  claim 3 , wherein a mounting plate is provided to which the sensor is fastened and on which the rotary axle is mounted, wherein the mounting plate is fastened in the region of the opening of the cavity in such a way that the rotary axle extends through the opening. 
     
     
         6 . The loader according to  claim 1 , wherein the loader is one of a front loader, a wheeled loader, a telescopic loader and rear loader.
