The 10 Most Frequently Asked Questions About Hydraulic Tools

  1. Why would I use a hydraulic tool over air tools?
    Hydraulic tools are self-lubricating and do not exhaust oil or particulate matter into the operator's work area.
  2. Why would I use a hydraulic tool over an electric tool?
    Electric breakers do not have the blow energy that hydraulic tools have – a 45# Hydraulic breaker is rated for continuous duty operating off a HTMA approved hydraulic circuit and will deliver 54’/# of blow energy at 1,800 blows per minute.
  3. What is the cost difference between air and hydraulic circuits?
    An air circuit will generally cost between $10,000.00 and $12,000.00. The hydraulic circuit can be operated by a self-contained gas engine or PTO driven off a truck circuit costing between $5,000.00 and $7,000.00.
  4. What is the cost difference between air and hydraulic tools?
    The air operated tools will generally cost approximately half that of a hydraulic tool. Based on the cost difference between the air and hydraulic circuit - for the same amount of money you can have a hydraulic circuit and two or three tools vs. an air circuit and one tool.
  5. Do hydraulic tools leak oil when connecting and disconnecting the tool?
    No with the development and use of flush face quick couplers that concern has been addressed.
  6. What can be done should there be a concern over an oil spill or ruptured hose?
    There are many biodegradable oils out there that can be used in Stanley Hydraulic Power Units and all Stanley Hydraulic Tools.
  7. Why would I buy a Hydraulic Cut-Off Saw vs. a gas-powered saw?
    “Power” for every GPM of oil you supply to a hydraulic saw you get approx. 1 HP. Thus your Stanley CO25 saw will deliver 8 HP. Plus you have a direct drive hydraulic motor directly driving the blade vs. a clutch and belt system on a gas driven engine model. No gas/oil mixture issues, No pull start cords breaking or getting hung up!
  8. What are the advantages of a hydraulic driven submersible pump or trash pump over a gasoline driven pump?
    All Stanley pumps are self-priming – they can run dry all day and not damage the pump. Gasoline driven dewatering pumps could be severely damaged should the pump run dry.
  9. Can I operate a hydraulic tool off my skid steer loader?
    Yes, however, we need to look at the tool hydraulic requirements – 7 to 9 GPM hydraulic flow range, 1,800 to 2,000 PSI operating pressure, 2,150 cracking pressure, 2,400 PSI full relief pressure maximum. With a backpressure in the return line of no more than 250 PSI. System requires a hydraulic cooler. Have your dealer flow your circuit and record the engine RPM when you reach 7 to 9 GPM of hydraulic flow on the auxiliary circuit. Since your skid steer has a bi-directional hydraulic circuit that is controlled by the operator, you must have your dealer instruct you so the pressure comes out the male coupler of the auxiliary circuit and to the “IN” port of the tool. Damage to the tool will result if you backflow the tool.
  10. Can I operate a hydraulic tool off my backhoe loader?
    Yes, however, we need to look at the tool hydraulic requirements – 7 to 9 GPM hydraulic flow range, 1,800 to 2,000 PSI operating pressure, 2,150 cracking pressure, 2,400 PSI full relief pressure maximum. With a backpressure in the return line of no more than 250 PSI. System requires a hydraulic cooler. Your backhoe loader should have a priority control valve in the auxiliary circuit. Most priority flow control valves have a manual selector so you can dial on the flow requirements. We want to set that selector to 8 GPM. Then have your dealer flow your circuit to ensure the proper flow is between 7 to 9 GPM of hydraulic flow on the auxiliary circuit. Since your backhoe has a bi-directional hydraulic circuit that is controlled by the operator, you must have your dealer instruct you so the pressure comes out the male coupler of the auxiliary circuit and to the “IN” port of the tool. Damage to the tool will result if you backflow the tool.
