TRACTEL BLOCFOR B10ESD - 070572

Tractel BLOCFOR 070572 is a retractable fall arrest device is suitable for use both vertically or with a deviation of 20 ° from the vertical, and for use horizontally without the use of a lanyard between the end of the strap and the harness.

Equipped with an ESD energy absorber that reduces the impact force even when the fall occurs with the rope completely extracted. The BLOCFOR 10 ESD is also ideal for users up to 150 kg, and guarantees an intervention distance of 80 cm.
Comes with steel M10 screw-lock carabiner and M47 triple-movement connector.

Features:
- Rope: 4.9mm metal strand.
- Carcass: ABS
- Effective length: 10m.
- Weight: 4.9 Kg.

How does an energy absorber work when and if you fall?

When an operator falls, due to the force of gravity, he begins to accelerate and then picks up speed.
The function of the energy absorber is to disperse the falling energy (produced by the acceleration) and it does so by “increasing” the stopping time (ie slowing down the acceleration due to the fall into a vacuum). In this way it does not allow the force generated by the fall to normally exceed 6 kN (about 600 kg).
Why 600 Kg? Roughly speaking, 600 Kg is the maximum that the human body can bear before the internal organs suffer from irreparable damage.

Under the action of the stop force, the stitches of the heatsink begin to tear progressively and the heatsink begins to stretch. Each stitch that tears dissipates some of the energy from the fall. Obviously the stitches are not all the same: the first, let's call them weak stitches, are affixed to yield around 250 kg and dissipate energy even in the event of a fall of slender people, otherwise the following ones will be suitable to compensate for weights and heavier energies.

Therefore the energy absorber limits the force transmitted to the operator, with the aim of preventing the exceeding of the 600 kg of energy on the operator's body on the anchor. How does all this happen? Extending the stopping time and consequently the stopping space.
