English to Spanish Tech/Engineering Forestry / Wood / Timber roundovers

Hi everyone! can you help me with the translation of "roundover"?
_The text is about safety regarding tree felling.

Context:

2. Use of ladders. Ladders shall be used according to the following:

a. Place feet of ladder parallel with top support and on a solid footing.

b. If the ladder is likely to shift or slip while it is being climbed, it shall be steadied by someone on the ground.

c. The feet of the ladder shall be placed a distance from the tree equal to about 25% of its vertical extended height.

d. A ladder shall not be climbed by one person while it is being held in a vertical position by another.

e. Ladders shall not be leaned against overhead wires or cables.

f. Never leave a ladder in a position from which it may fall.

g. Never leave a ladder where it presents a tripping hazard.

h. A ladder shall not be used to support weight in a horizontal position.

i. A defective ladder shall not be used.

j. Occasionally, as in the case of some roundovers, a ladder must be used in a tree. When this is necessary, the ladder shall be set as solidly as possible and firmly lashed in place. This requires your direct supervision.
