First Thing’s First
First, we need to determine what size Crossover Bridge you need. One of the most common mistakes made in ordering many ladders is getting them too large for the available workspace. Here are some things to consider before ordering your new Crossover Bridge:
*SpaceSaver Crossover Bridge shown.
A: Standing Height
The approximate height that a person would stand while on the bridge. You will want to be sure that the user can stand comfortably on the platform without obstruction. We calculate this at 6 feet, but individual standing height will vary.
B: Overall Height
is VERY important. You want to be sure that your ladder will not be too tall to fit into your workspace. This includes being able to fit through any doors that you may need to move it through, or under any ceilings or fixtures that you may have.
C: Platform Height
is the measurement of the top step from the ground. It’s important that this measurement is not too far above or below your desired working height.
D: Base Width
is also very important because as ladders get taller, the base width increases. It is important to be sure that the ladder will not be too wide for your workspace. We offer different tread widths to accommodate most work areas.
E: Overall Length
is the measurement between the floor-mounting brackets. This is dependent upon the height of the bridge. The taller the bridge, the longer the overall length. Lower clim angles also increase overall length..
