Backhoe Loader Hydraulic: The Heart of Machine

May 14, 2017 The above mentioned simple system however isnt good enough for a backhoe loader since the pistons need to be able to both push and pull. A piston system called a hydraulic ram is used in a backhoe loader. The ram is fed by hose on both ends letting the piston move in both directions as required by applying pressure from the required end.

Hydraulic Power How Caterpillar Backhoe Loaders Work

Mar 05, 2001 In the backhoe loader shown above, the hydraulic system pumps oil at up to 3,300 pounds per square inch, and the cylinder pistons in the backhoe arm have a diameter of up to 5.25 inches. This gives each cylinder piston a force of 70,000 pounds!

Hydraulics in the Backhoe How Caterpillar Backhoe

Mar 05, 2001 Backhoes also have stick lift and boom lift ratings, which tell you the maximum weight the stick and the boom can lift individually when the hydraulic rams are pushing with full force. This is another measure of a backhoe's general capacity, and is especially useful for contractors who plan to use the backhoe as a sort of crane for lifting
