Definitions

  • the present invention relates to a running fall arrester for fall protection of persons on a safety rope with a housing, a fastening eye for a man rope, which is attached to the Peron to be secured, and with a pivotally mounted on the housing brake shoe, which in a braking position and a release position for the safety cable running through the housing is pivotable, according to the preamble of claim 1.
  • a fall brake for fall protection is known, which is connected via a short man rope with a person to be secured.
  • This case brake has a housing which can be slidably mounted on a safety line, which is normally vertical, and a plurality of lever-type brake elements arranged in the housing and cooperating with the safety cable.
  • a lever is provided, which is pivoted in the event of a crash with respect. The housing and brings the brake members in a braking position.
  • the invention is based on the object, a fall arrester og. Type with respect to the structure and the tracking characteristics on the safety rope to improve.
  • the housing is U-shaped with two legs and a base body, wherein a pivot axis for the brake shoe at an open end of the housing and the two legs connecting to each other is arranged such that the two legs, the brake shoe and the main body together form a passage guide for the safety rope, wherein the attachment eye for the man rope is arranged on a side facing away from the passage guide of the base body.
  • a particularly small design and simple and cost-effective production of the fall arrester is achieved by the fact that the legs and the base body are integrally formed with each other to the housing.
  • the fastening eye is formed integrally with the main body of the housing.
  • the brake shoe is resiliently biased in the braking position by means of a spring.
  • a follower catcher comprises a U-shaped housing 10 which is integrally formed of two legs 12, 14 and a base body 16.
  • a brake shoe 18 is arranged pivotably on a pivot axis 20 between the legs 12, 14 with respect to the housing 10.
  • the pivot axis 20 is located near an open end of the U-shaped housing 10. The arrangement is made such that the legs 12, 14, the brake shoe 18 and the base 16 between them form an enclosed passage 22 for a safety rope 24.
  • a fastening lug 26 for a man rope 28 On a side facing away from the implementation 22 side of the base body 16 is also integrally formed with the base 16 a fastening lug 26 for a man rope 28.
  • This man rope 28 is used to connect the fall arrester with a safety harness, not shown, which is worn by a person to be secured.
  • a spring 30 is provided on the pivot axis 20, which biases the brake shoe 18 in the illustrated braking position.
  • the safety rope 24 is attached to a high point 32 and pushed through the passage 22 in the direction of arrow 34.
  • the fall arrester In the normal state of the fuse, i. the person to be secured moves slowly relative to the safety rope 24, the fall arrester is located at a geodetically lower point than the person to be secured and at the same time the mounting lug 26 at a geodetically higher point than the safety rope in the implementation 22nd
  • the housing 10 tilts into the in Fig. 1 shown position as soon as no or only small force on the man rope 28 acts.
  • the corresponding high train 44 ( Fig. 3 ) on the man rope 28 together with the friction between the brake shoe 18 and the safety rope 24 causes the housing 10 to tilt and the biased brake shoe 18 and the safety rope 24 to tilt against each other thereby stopping the falling person's fall.
  • the device does not jam immediately, but dampens the impact force by a controlled Nachg cybersecurity.
  • the person to be secured then hangs after a short fall distance on the safety rope 24 and can be recovered without significant time pressure.
  • the attachment lug 26 is arranged eccentrically on the housing 10, so that in the event of a crash, the housing 10 tilts about an axis parallel to and spaced from the pivot axis 20.
  • the safety cable 24 strikes the first end 40 of the brake shoe 18 at a distance from the point 36 and exerts a pivoting force on the brake shoe 18 in the direction of the arrow 46 such that the brake shoe 18 engages a point 36 facing the second end 42 is pressed against the safety rope 24, and the stronger, the stronger the train on the man rope 28 is.
  • the safety rope 24 is determined by friction within the bushing 22 and prevents sliding of the catching device relative to the safety rope 24.
