Quick Quote

When arresting a fall, forces between 4 and 6 kN are always produced, even with shock absorbers.

Fatal injuries can result unless these impact forces induced by fall arrest are transferred and distributed to the human body in a functional and ergonomically consistent manner.

Fall Arrest Harness EN 361

Seat Harness EN 813 in combination with the chest harness EN 12277

Catch eye position

Dorsal

Sternal

Sternal

Force Induction

From the rear top into the crotch and pelvis

From the front top, diagonally to the buttocks

From the front top into the thighs

Reactions

Slight kink in the hip, the body slumps into the harness

Buttocks and hips are pushed forward

The thighs are lifted to a position similar to that when seated

Force Distribution

Mainly into the crotch (possible genital injury)

Mainly into the buttocks. Relatively direct force induction into the spin

Mainly unto thighs. Ergonomically consistent, because the thigh is one of the strongest anatomical part of the human body

Suspended position free hanging

Extremely passive bent forward position

Upright position

Upright position, similar to that when seated

Application Criteria

  • Free suspension is not possible (retention)
  • Fall arrester with shock absorber
  • Controlled descender
  • Immediate measures (rescue, lowering to ground) are possibly by other

In conjunction with a fall arrester with shock absorber suitable for all types of safety against falls from limited heights, e.g. climbing with a follower type climbing protection device

In conjunction with a fall damper suitable for all areas of safety against falls from limited heights.

Together with appropriate security measures (dynamic fall arrest at high risks of fall and/or great heights

Suitable for work in vertical positions with climbing and lowering action

The ergonomically safest variant to arrest falls and for free suspension is always the combination seat harness and chest harness

Capability of action when free suspended

  • Highly restricted capability of action
  • Self rescue not possible

Easily reachable attachment point, however the slightly hyper-extended position is very steep entailing a restricted capability of action

The suspension position similar to a seated position guarantees maximum capability of action

Convenience during suspended

Minimum

Medium

Optimum

Duration in the suspended position

As short as possible

Despite of a more favourable suspended position, the duration should not exceed a maximum of 10 minutes

With the correct selection and matching of the harness, the duration in the suspended position can be 15 minutes or more without any problem
