Rotzler Tarvos / snatch block

Dynamic and powerful

The Tarvos snatch block is used to increase the power of winches and doubles their drag force to up to 60 tons. It is used in emergencies or for pulling of heavy machinery in case that the winch itself cannot provide the necessary force.


The dynamic and powerful design of the snatch block underlines both, the strength and lightweight of this new product. The structure protects less robust components from damage in the everyday use. The two identical die-cast aluminium parts saves weight by a smart design and therefore ensure a light weight for all of the block sizes. Due to this design the use of the snatch blocks becomes possible, even for the biggest one with a maximum size of 650mm.

"Graphical user interface (GUI)"

In computing, a graphical user interface (GUI) is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces which require commands to be typed on the keyboard.

The actions in a GUI are usually performed through direct manipulation of the graphical elements. As well as computers, GUIs can be found in hand-held devices such as MP3 players, portable media players, gaming devices and smaller household, office and industry equipment.
