How to determine the maximum number of cabinets in an array
The allowed number of cabinets in an array is determined by the following factors:
1.
The allowable loads on the supporting construction (e.g. roof, crane, trussing framework
etc.).
2.
The Weight Load Limit (WLL) of the hoisting motors.
3.
The WLL of the flying frame
4.
Local rigging legislation on safety factors etc.
5.
The configuration of the array !
Note: A chain is as strong as its weakest link! Therefore all of the above criteria should be
determined and should NEVER be exceeded!
1. Supporting construction
At public facilities the allowable loads on a roof construction or support is available at its
authorized engineering office.
2. WLL of (motor)hoist
Refer to manual of the hoist manufacturer
3. Flying frame WLL
Never exceed the safe Work Load Limit indicated on the
S
asy-rig™ Flying frame or as indicated
by the software SPArC™.
4. Local rigging legislation
All
S
asy-rig™ rigging hardware is designed with a safety factor 10. This is well above the
European safety standards as stated in the Guidelines for Machines. Local laws, however, may
enforce higher safety factors and/or restrictions or demand other safety precautions.
