Mountain support
The mountain support is a component from the early days of the automobile to prevent the vehicle from rolling away on the mountain. The support could be operated from the driver's seat and could also be used as a starting aid.
It was a long iron claw that was lowered when parking on inclines and anchored in the ground. Later it became a lowerable shield , now mostly hydraulic , which is used on work vehicles with a winch on the back of the wood as a support for the strong ends of the logs to be pulled. At the same time, the mountain support prevents the vehicle from being pulled towards the object to be pulled.
In the form of a stick, the mountain support was already on travel carriages from around 1830.
