rated capacity vs. lifting capacity ? 743 specs
Posted: 03/24/2009 04:31 PM
As you can see the Rated Operating Capacity below says 1300lbs. The Tipping Load says 2600lbs. I need to lift a pallet of plywood that has 35 sheets that I estimate to be about 1600lbs total off of a semi and bring it to my rear yeard. Is it safe to do. What is the different between tipping load and Rated Operating Capacity? 743 Engine Cooling Liquid Emissions Tier (EPA) N/A Engine Fuel Diesel Horsepower 36 HP Turbocharged Engine N/A Rated Operating Capacity (SAE) 1300 lbs ROC with Counterweight Option N/A Tipping Load 2600 lbs Operating Weight 4720 lbs Travel Speed N/A Travel Speed (2-speed option) N/A Fuel Tank N/A Pump Capacity 11 GPM Auxiliary Std Flow 11 GPM Auxiliary High Flow N/A Length 120.4 in Length with Standard Bucket N/A Width 55.1 in Width (with bucket) N/A Height 75.8 in Height with Operator Cab N/A Height to Bucket Hinge Pin 109 in Reach @ Maximum Height 21.8 in Turning Radius N/A Wheelbase 35.4 in Joystick Control N/A Air Conditioning N/A Backup Alarm N/A BICS System (Interlock) n/a Cab Enclosure N/A Cab Heater N/A Suspension Seat N/A Deluxe Instrumentation N/A Engine Shutdown N/A Hydraulic Bucket Positioning N/A High Flow Option N/A Auxiliary Hydraulics std Bob-Tach Attachment System std Power Bob-Tach N/A Ride Control N/A Horn N/A Chain Size Final N/A

hmmmmm usually I would have a feel of wheather it's gonna try to tip when you get the arms level. your load center is 24" away from your tach. you should get a good feel of it when you pick it.

It has a safety margin built in there, not sure on the sums but its there all the same. Its rated at X amount, it can lift this all day every day and is called the ROC (rated operating capacity). Now as stated, this has a safety margin so its totally safe lifting this much weight at the base of the bobtach.

Now, i have lifted rather large objects that were way over the ROC of my machine, it was very light on its rear wheels but managed to get the job done. The biggest issue you will have is the measurements i believe are taken at the bobtach, the further out you get the less you can lift. I assume your ply wood is full sheets so around 1.2m wide x 2.4m long. Hopefully that isn't too far out to cause an issue of tipping the machine, but something you need to look out for.

well if i was coming from the ground I wouldnt be so worried but lifting from a semi once you back off well you are along for the ride. If the tipping load is 2600lbs then i should be ok just not sure why they put the 1300 lbs on there

The plus side is I do not need to keep them high for long. pretty much lift and lower close to the ground and roll. Only traveling a total of 100 feet once i get to the ground.

The problem is the 1300 lb roc is not valid becase the loads center of gaveity is extended out is front of the loader, below is a pic from Bobcats pallet frorks with ratings for loads who center of gravity is 24” out on the forks, which yours are.

They are saying the roc in this situation is 690 lbs, your tipping load is likely (my best guess) double this, say 1380lbs.

Also park the truck some place where you can back downhill or level away from the truck, if you must back uphill the capacity is further reduced by the torque on the drive wheels.

My “guess” is 30 sheets max

so to play it safe 100% i should really have anymore than 15 sheets at a time. Thats sucks. They advertise forks that have a capacity of 4000lbs but that doesnt make much sense if the best they can get is half of that with counter weights.

Try and pick the load and see what it does.You can sense if it's too much you can let it down.Like the previous post reccomend being on the downhill side makes a big difference. Scott

Lucky for me I found out the trailer has a lift gate. So it will just be a matter of picking it up off the ground a few inches to move it instead of having to lift it off the trailer.
