Pump jacks are a uniquely designed scaffold consisting of a platform supported by moveable brackets on vertical poles. The brackets are designed to be raised and lowered in a manner similar to an automobile jack. Pump jacks are appealing for certain applications because they are easily adjusted to variable heights, and are relatively inexpensive.
NOTE: The requirements on this page are specific to pump jack scaffolds only. For requirements that apply to all types of supported scaffolds, please refer to the Frame or Fabricated module of this eTool.
Poles must be secured to the structure by rigid triangular bracing, or equivalent, at the [29 CFR 1926.452(j)(2)]:
Other points as necessary
When bracing already installed has to be removed so the pump jack can pass, an additional brace must be installed approximately 4 feet above the original brace before it is removed. The additional brace must be left in place until the pump jack has been moved and the original brace reinstalled. [29 CFR 1926.452(j)(2)]
