Limits that apply
- OSHA 29 CFR 1926.451(c)(1) and 1926.452(w): the height is at most four times the least base dimension unless the tower is restrained; nobody rides a moving tower unless 1926.452(w)(6) is met; castors are locked while in use.
- Load as the manufacturer states it: 6' length: 1,000 lb distributed; 8' and 10': 500 lb
- ScaFix lists the parts from the manufacturer's tables. It is not a structural approval: the assembly and use instructions on site govern, and a competent person inspects the tower.
