Fall arrest blocks are used to protect against falls. They have an automatically retractable steel rope or belt strap, which keeps the connection taut at all times. In the event of a fall or if maximum work velocity is exceeded (approx. 1.5 m/s), centrifugal force engages the stopping blades, preventing the fall. The required stopping power is sup- plied by an integrated braking system. (...) We offer fall arrest blocks in the following variants: with swirl-, or hanging suspension, in plastic or aluminium housing, with belt strap or steel rope, (galvanised as standard, also available in stainless steel for an extra charge). We can also supply fall arrest blocks with an additional rescue lifting device, which makes it possible to lift or lower an accident victim using the appropriate hand crank. Especially for climbing parks and sports facilities, we offer a fall arrest block/rescue device with digital counter. The counter shows exactly the number of descent trans- actions.With this device are 12,000 descent-meter possible without an Expert testing.The device is equipped with a specially developed backup system which is used in the case of brake failure by overstressing the device.
