Fall Arrest System Design Loads

Rope grab means a deceleration device that travels on a lifeline and automatically by friction engages the lifeline and locks so as to arrest the fall of an employee. Load halt fall arrest equipment load arrestors work on the principle of inertia.

Fall arrest system design loads.

A rope grab usually employs the principle of inertial locking camlever locking or both.
You fill in the project information such as the applicable standard en ansi or csa and the foundation material.
Engineering fall protection and fall arrest systems our staff of in house structural engineers design each fall protection system to specification based on your facility.

Safety factor means the ratio of the design load and the ultimate strength of the material.
Another common system is an hll horizontal life line.
Our specifications include calculating pertinent factors such as dynamic load requirements peak loading soil bearing pressure and structural attachment points.

Fall protection design shall consider prompt rescue procedures in the event an employee is subjected to a fall using a fall arrest system.
The amount of time workers will spend connected to the fall arrest system.
Reason being that fall arrest systems have some type of deceleration device that engages after freefall and reduces the force.

The areas of the roof which need to be accessed eg.
Emergency contact information and rescue procedures shall be laminated and posted at all roof access points.
It matters because the forces incurred during a fall of a 220 lb.

The system allows you to test designs and loads to ensure the right system is chosen for the application.
Then you move on to the system setup.
The frequency of use of the system.

Even with a safety factor of two an engineered system rated for applied loads ranging from 1800 to 2400 pounds is a very different than a 5000 pound anchor point.
Inertia is the same method used in retracting car seat belt systems to sense rapid movement and lock on to arrest the movement.
Odin calculates the dynamic behavior of a complete fall protection system.

With an engineered system it is not uncommon to see applied loads ranging from 900 to 1200 pounds for a single user during fall arrest.
It is essential that the ppe be rated for fall arrest and ppe used with static line include an energy absorber.
While the energy absorbing lanyards hold in excess of 5000 lb 2300 kg when fully absorbed most limit the load during the fall to under 1400 lb 640 kg.

The certified fall arrest system must be marked on the as built drawings with the pe seal.
Worker who is utilizing a fall arrest system could be approximately 900 lbs not 2500 lbs.
The number of workers likely to use the fall protection system at any time.
