Abstract (en)
The specification describes a front loader for fitting onto a supporting vehicle, with a quick-change frame for interchangeable tools which is coupled to the free end region and can be swivelled by tipping cylinders, at least one locking pin being mounted on the frame, which pin can be moved at a given unlocking signal from a locked position fixing the tool to the quick-change frame to an unlocked position releasing the tool, by a hydraulic auxiliary force against the force of a resilient element. In order to have a simpler, more favourably priced construction while retaining the advantages of known front loaders, the locking pin (23) can be moved into the unlocked position by an actuating mechanism which becomes active only in response to the unlocking signal, and which responds to the increase in the distance between the locking pin (23) and the front loader (2) which takes place when the tipping cylinders (18) are drawn out. <IMAGE>
