MC400L  Key Features:

  • High-Torque Motors: Deliver the power required to handle heavy loads with ease.
  • Rigid Arm Structure: Ensures exceptional stability and minimizes deflection during handling.
  • Advanced Control Software: Precisely control movement paths and optimize handling operations.
  • Collision Detection and Avoidance: Protects the robot and surrounding equipment from accidental damage.

MC400L  Ideal Applications:

  • Automotive Manufacturing: Handle car bodies, engine components, and other heavy parts.
  • Metalworking and Foundry: Lift and transport large castings, dies, and molds.
  • Heavy Machinery: Maneuver heavy machinery components and assemblies.
  • General Manufacturing: Automate material handling tasks for various heavy objects.
  • Construction Industry: Handle concrete blocks, steel beams, and other building materials.

1[rad] = 180/π[°], 1[N·m] = 1/9.8[kgf·m]

(*1) This value changes by placement and load conditions of a wrist.
(*2) The Allowable moment of inertia of a wrist changes with load conditions of a wrist.
(*3) This value conforms to “JIS B 8432”.
(*4) The initial setting of the software limit is ±210°. When installing the cables in the hollow hole part of J6, please use the robot in the range of ±210°.
If the cables do not go through the hollow hole of J6, it is possible to widen the operating envelope of J6 up to ±360° considering the condition.
(*5) Permitted height is not higher than 1,000m above sea level. If used in higher place, permitted temperature is affected by height.
