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.

simplify the understanding of design Glossary
Design and functional development of a user interface. Interface is a part or an act, in which a person makes contact with a machine or a product. The simplest example therefore is a light-switch: it‘s not part of the person, neither part of the machine (light), but an interface between. For being useful and important for persons, the interface should be based on human needs and skills. If you look at it systematically user interface belongs to the „Man Machine System“ (MMS): Man ↔ Man-Machine-Interface ↔ Machine. Different sciences are focused on that theme, e.g. informatics, the Cognitive Science research and psychology. The basic knowledge for user-friendly interface design is developed in design and ergonomics. The specific field of activity is Cognitive Ergonomics, System Ergonomics and Software Ergonomics (usability engineering).
