Well, after years of software development we have finally published a web based software tool that will give you the kind of accurate capacity rating information you are looking for and you don't have to be technically inclined to use it. You will still want to obtain your capacity rating plate from the manufacturer once you actually purchase or install the equipment in the field, but the website was designed by forklift capacity rating engineers and allows you to build up a forklift with drop down menus, add up to three attachments to the front, also with drop down menus, and finally select a load center and hit a button to calculate your capacity. You can change the load center and instantly recalculate the capacity and the program also tells you whether you have too much or too little attachment or fork capacity so you can go back and optimize the configuration to get the best capacity at the lowest cost. We have populated the database with thousands of attachment and forklift models and continue to add to the list daily. You can register for a free trial at lifttruckcapacitycalculator.com or forkliftcapacitycalculator.com. Take a look and give us some feedback on how we can improve it. Enjoy!
