can you stand on the platform ladder

Asked by: safety
The platform ladders are designed so that the user may stand on, and work from the platform while being in compliance with OSHA and ANSI standards. The platform provides a large standing area, so that the user may comfortably stand and work at a consistent height.

Is there a user manual for these ladders?

All of the dimensions are published online which is great, but what about a safety fact sheet or user manual that covers all of the safety associated with use and setup of your ladders? Is that available online somewhere that I am not seeing or do I need to call you for a copy?

Why does the platform ladder weigh so much more than the regular single side non platform ladder?

On the 10 ft step ladder, I noticed on the compare section of the aluminum step ladder and the aluminum platform ladder the weight was almost double for the shipping weight. Why such a big difference? I expected it to weigh more but not that much. It doesn't seem like there is that much more material. It is even significantly more weight than the single sided fiberglass ladder.
Asked by: Phillip
The PT310 weighs 58.5lbs (platform twin ladder). The T310 (twin ladder) weighs 43lbs. The 310 weighs 31lbs. The PT ladder not only has the platform but it also has the twin access as well. There is also a safety guardrail that has to be in place as well. Even though all of these ladders are rated at 300lbs, they PT ladder has a 300lb load capacity on each side. Small factors like this can make up the difference in weight.

Different types of ladders are designed to keep you safe and productive when climbing or standing. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.
Height is referring to the actual ladder height. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. The highest standing level is four rungs down from the top. The highest permitted standing level on a stepladder is two steps down from the top.

Reach height is the maximum reach assuming a 5’6” person with a vertical 12” reach.
Ladders are designed to safely hold up to a specific amount of weight. The Werner Performance System defines five different capacities using a color and star rating system. The Duty Rating is defined as the maximum safe load capacity of the ladder. A person’s fully clothed weight plus the weight of any tools and materials that are carried onto the ladder must be less than the load capacity.

Werner offers ladder made from fiberglass and aluminum. Each material has characteristics which make it best for certain applications, or one material may simply fit the personal preferences of the user. For example, if working around electricity users should select fiberglass products due to their non-conductive side rails.
