The backhoe no longer has to lift the weight of the bucket.īut here’s the most important lesson: because each manufacturer designs their backhoe geometry a little differently, the load charts for different backhoes vary in different ways.
Take extra care to be sure loading the machine closer to the edge of the trench doesn’t collapse the trench wall.Īnother option for improving lift capacity: drop the bucket and rig to the eye on the coupler. You may have to move the machine closer to the trench in order to land the load in the same place you could reach if you were doing the work with the boom. Specifications: Case 580 Super N WT Backhoe Specifications, Lfit ChartĬAUTION: lifting with the dipper will reduce your working radius – as you lower the load into place, it will move toward you. – 37% more than its max boom-lift capacity. above grade with a standard stick, is 5,562 lbs. For example, a Case 580 Super N WT’s least dipper lift capacity, at 8 ft. With a shorter swing radius, the stick has mechanical advantage. When you’re lifting near the backhoe’s capacity out of or into deep excavations, longer rigging keeps the boom up in its most powerful working range.Īnother way to get more lifting power when you bump up against a backhoe boom’s lift capacity is to lift with the dipper-stick cylinder. Pullen recommends keeping a couple of lengths of good rigging with your machine. “But if you try to pick the old box out of the hole using the same chains you stall it out.” “You can lift a septic tank off the truck with no trouble at all,” says Katie Pullen, brand marketing manager for Case backhoe loaders, noting that the boom will be raised high to unload the truck.
below grade can be as much as 15% more than 400 lbs. below grade, and the difference between the backhoe’s capacity at 12 ft. Many are at their lowest lift capacity around 4 ft. above grade, where most of them are at or near the maximum capacity.Īt most other places in their working range, a backhoe’s lift capacity is less than its rated max. But if all you have is a backhoe’s maximum rated lift capacity, you really only know enough to be dangerous.īackhoe lift capacity is most commonly rated based on their boom capacity at 12 ft.
Safe lifting with a backhoe, or any machine, starts with knowing the weight of your load and the capacity of the machine.
