I-beam dimensions for 1t capacity N(RM) Electric Chain Hoist (With Electric Trolley)

Good Morning

I have a query about 1t capacity N(RM) Electric Chain Hoist (With Electric Trolley)

The brochure extract below suggests a 80-160mm limit for the I-beam.

Is this the width of the I-beam flange? i.e. dimension “b” shown below?

If so, we were proposing to use a steel beam 305x165 UB 54. For this beam the width b=167mm.

Would this be acceptable for use with the 1t hoist? or is it strictly <160mm?

Extract from technical brochure:

RAMHOIST: 80-160mm is the standard width of the I-beam flange, we can make the 1t hoist to suit your width b=167mm
