Application

  • alkitronic® AB – Battery driven 2-speed torque multiplier for torques from 90 Nm to 4,000 Nm (65 to 2,950 lbf.ft)
  • Short fastening cycles: Fast gear for run down and power gear for highest torques and precision.
  • Mobile and always ready for use: Compact design for convenient working in limited spaces or without power supply.
  • Efficient operation: Fast and easy gear-changing, great torque range – you can choose from 22 torque values.

Advantages

  • Low running costs: The low-wear brushless synchronous motor is maintenance free.
  • Health-preserving: Low weight, ergonomically designed, low noise emissions. No noise protection necessary.
  • High performance: Two lithium-ion battery packs ensure up to 360 screw joints in a row. Each battery features a LED charge level indicator.
  • Exact shut-off torque even at low battery levels.

alkitronic® Specials

  • Very low susceptibility to damage and failure: Motor housing made of special polymer: Break-proof, impact-proof and resistent to corrosion.
  • Intelligent energy management and faster workflow: Electronics protects battery cells from overcharging and depth discharge. Cooled
  • battery packs during recharging. This reduces charging times and enhances maximum performance and durability.
  • Proven high-performance gears, produced in a chip-free high-precision proces
