fångstblock

Fångstblock is a term used in Swedish to describe a mechanical device designed to catch, hold, or control a rope, line, or load in rigging, lifting, rescue, and related applications. The word combines the idea of catching or securing with the function of a block or pulley.

A fångstblock typically consists of a housing that encloses a pulley or friction surface, through which a rope or cable runs, and an attachment point for an anchor, hoisting line, or supporting structure. Depending on the design, it can be fixed or movable, manual or automatic, and may incorporate locking mechanisms, clutches, or brakes to prevent uncontrolled movement. Some versions are designed specifically to catch a falling load, while others serve to redirect or change the direction of a rope system.

Common uses include forestry and logging operations where blocks are part of cable systems used to move timber; rescue and rope-access work where a fångstblock helps arrest a fall or secure a line; and industrial lifting or rigging where it contributes to controlled lowering or raising of loads. In all applications, the block functions as part of a rope-and-pulley arrangement that provides mechanical advantage, improved control, or safety by limiting unwanted movement.

Safety and maintenance are essential. Fångstblock must be selected with appropriate load ratings, regularly inspected for wear or damage, and used in accordance with applicable standards and training. Proper rope compatibility and correct installation are crucial to ensure reliable performance and to minimize the risk of failure during operation.
