This is one of those questions that no one will will tackle because there are other factors that weigh into this type construction: Angle of lift, How will the new beam be supported, Is the foundation sufficent, indoors vs outdoor ect. I'm afraid we do not have enough information to safely answer your question.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
Purlins are used on double roofs. They effectively reduce the span of the rafters and limit their size to ecenomical sections.
use 400x400mm with a rebars of 8-16mm dia. for 4-5m span.
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span
We may suggest 20ft (6m) to be the criteria but i insist this is practically too short. Bridge span of 20meters or less may be a good standpoint reference of "short span".

It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati

Tell us the size of the span, and what it is made from, and we may be able to get you an estimate. A single 6 foot board is 5 seconds, a 300 foot long concrete and steel span takes a little longer.

A DLH will work.
2X8 set 16 inch on center.
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.
For a standard size poodle, the life span is about 12 years.
That can't be answered without seeing the details of your plans.
You can reinforce steel by either decreasing the span length or increasing the stiffness of the steel. Reinforcing steel improves safety and design effectiveness and decreases deflection.
