Pines #1 Hydraulic Tube Bender Rebuild Sample

CONDITION: Refurbished

Rebuilt PINES #1 RH Hydraulic Tube Bender To Include:


  • Bender is upgraded with a COMPTROL digital controller. The controller is by Sierra Controllers. See for detailed information. The controller is has a quick disconnect to the main electrical box. We use the orange anaconda non-metallic not the gray metallic. This way if you step on it or happen to drive the forklift on it, it will not crush it and damage the internal wiring. Specifications are listed below.


    1. Intuitive menu driven part & setup screens
    2. Each bend parameter can be programmed specifically for each bend
    3. Alpa-numeric part names
    4. Massive Part Storage & bends per part
    5. Integrated manual & automatic controls
    6. Programmable mandrel oscillation
    7. Early Mandrel Extraction
    8. (3) Return Modes (manual, semi-automatic, & automatic)
    9. Pressure Die Assist (Boost) delay
    10. Bend Arm deceleration (If bender is equipped hydraulically)
    11. Automatic parts counter
    12. Status line for the run mode
    13. Display of Bend arm angle & current part bend data
    14. Easy enabling & disabling of bender devices
    15. Easy toggling of bender inputs
    16. Two mandrel extractor sequences
    17. Automatic Mandrel lube intervals (If bender is equipped)
    18. (4) Line x (20) character Vacuum Fluorescent Display
    19. Controller board cover by (2) year warranty
  • Machine cleaned, sanded & painted. Color Blue & Safety Yellow unless other specified.


  • “”NEW” Swing Arm – Custom To Accommodate (50” Diameter):
    1. Removed original swing arm assembly
    2. Design & Manufacture New Swing Arm – Slide Length Approximately 31” Long (Tee Slots machine thru & add extension block for adjustment screw) (A spare extension block will be provided with and extra back up screw & nut)
    3. New Safety Plate
    4. Remove & replace Timken cup & cone bearings
    5. Replace spanner nuts
    6. Replace spindle key


  • “NEW” Stationary Arm– Custom To Accommodate (50” Diameter):
    1. Design & Manufacture New Swing Arm – Slide Length Approximately 31” Long (Tee Slots machine thru & add extension block for adjustment screw) (A spare extension block will be provided with and extra back up screw & nut)


  • Manufacture NEW top sections for the Swing and & Stationary arms for the larger CLR’s up to 50” Diameter. These will mount to the slides similar to what is existing. Roller Bearing Style with wear plate under so the bearings will not contact the 60-1/2” Diameter Plate
  • Hydraulic cylinders:
    1. Rebuilt Bend Cylinder or New
    2. Rebuilt Clamp & Pressure Die Cylinders or New
    3. Rebuilt Mandrel Cylinder or New


  • Hydraulics All New:
    1. New Manifold
    2. Bend Valve & Flow Control
    3. Clamp Valve & Flow Control
    4. Pressure Valve & Flow Control
    5. Mandrel Valve
    6. Decel Circuit (Will not need – customer running machine cycle slow and speed of arm can be slowed down by the flow control behind the bend valve)
    7. Piston Pump
    8. The suction strainer, oil sight glass & pressure gauges are replaced
    9. New hydraulic hoses
    10. New Hydraulic fittings


  • New gaskets on side oil tank covers
  • New Lube USA electronic slide lubricator. Includes new junctions, meters, line, ferrules, & fittings
  •  New main electric motor (TEFC) Totally Enclosed Fan Cooled C-Faced Adapted w/New Coupling



  • Electrical:
    1. New disconnect box (Machine VOLTAGE 460/480)
    2. New fused disconnect switch
    3. New motor starter
    4. New transformer
    5. New wiring
    6. New switches
    7. New fittings
    8. New Fuses
    9. Switch added for clamp close


  • New Rear Sprocket pin & bushing


  • New Front & Rear bend chain & connecting links


  • New Pressure Die Holder Assembly – Linear Rail & Bearing Style


  • Master Bar Assembly:
    1. New master bar face plate
    2. New master bar middle plate
    3. Add adapter for old style pressure die tooling


  • New Clamp Die holder assembly. Adjustable t-slot face


  • Machine cycled & tested. Sample material & a set of tooling are required to be provided by customer.


  • New Base Extensions with Legs included extending the machine length for the mandrel extractor to the same length as the existing length. Will require (2) 10’ extensions that will be bolted and approximate 3’ extension welded to the machine base. Extensions could vary depending on the exact machine length we purchase.


  • Manufacture new tube clamping assembly. Will have shut off flow controls so it does not cycle when not needed. This assembly is used to clamp onto the tube and keep it in position while the tooling wraps the material around the radius die/chains. Adjustable to the 50” Diameter / 25” CLR.


  •  Controller Key Pad
    • Controller Power Supply
