Three Roll Linear Axis Hydro Manual – (Model No. 3R----LAHM)

The machine is most economical model among all plate bending machine and is most useful for small fabrication shop.

Advantages :
  • Specially developed hydraulic circuit requiring minimum maintenance.
  • Since all rolls are mounted in roller bearings the electrical consumption is less by 50% compared to conventional pyramid type machine.
  • Since all roll movement and roll rotation is through hydraulic actuator, only one person is required for operating the machine without efforts.

Special Features

The machine frame is fabricated from all tested steel plate material. A Die Penetration test is carried out on all weld joints to ensure sound weld quality This frame is subjected to stress relieving, sand blasting and epoxy primer painted for corrosion free long lasting machine life.( Primer paint 160 DFT) The complete body frame is machined in CNC machine to achieve built

A tilt able control desk is conveniently located on machine. The main panel start / stop buttons and roll rotation function (Reverse / forward) is provided on the same. The Top roll left side position and right side position are indicated separately by two digital meters

A specially designed & built mechanism allows drop end frame to tilt down in horizontal position without much efforts (one person can perform job). No need to dismantle frame from main body like in conventional machine.

All our machine rolls are mounted in heavy duty roller bearings. Each roller is fitted with two bearing per side (four bearing per roller)

A dual cone bending device can be provided as shown. The attachment provided between bottom rolls is suitable for narrow cone diameter. The attachment to be fitted on a main frame is suitable for cone having wide angle.


An extended rolls can be provided for mounting dies to roll different sections like angle, channel, beam, pipe or flat etc.



Standard Featues
  • All rolls are manufactured in alloy steel material
  • Both the bottom rolls are positively driven by inline mounted planetary gear box and hydraulic motor.
  • Possible to place side roll in inclined position for conical rolling.







Optional Featues
  • A special alloy steel material for Hardened rolls. Hardness up to 52-60 RC.
  • All 3 rolls positively driven
  • A seprate cone bending attachment can be provided for narrow diameter cone forming.
  • Provision for section rolling.
  • Section bending dies.
  • Overhead support.
  • Lateral support.
  • Auto plate squaring reference stopper.
  • Tilt able top roll.
  • Automatic roll speed compensation.
