Installation with lowering device

The mixer is lowered into the basin using a lowering device. The lowering device’s guide pipe safely guides the mixer to the duty point. The resultant reaction forces are transferred directly into the foundation via the lowering device. The foundation must be designed to bear this load!

CAUTION! Material damage due to incorrect accessories! Due to the high reaction forces, the mixer may only be operated with the manufacturer’s accessories (lowering device and frame). If the mixer is ordered together with a lowering device for installation, the frame comes pre-assembled. If the mixer is delivered without a frame, order the appropriate frame from customer service!

  2. Frame mounted on the mixer.
  3. Lowering device mounted in basin.
  4. Hoisting gear with sufficient bearing capacity provided.
  1. Attach lifting equipment to frame with a shackle.
  2. Version with plastic rollers: Loosen linchpins and dismantle plastic rollers and quick-release axles.
    NOTICE! Prepare components for further installation.
  3. Lay all connection cables and mount cable brackets.
    The cable brackets fix the connection cable to the lifting equipment and prevent uncontrolled floating of the connection cable in the basin.

  1. Preparatory tasks completed.
  1. Lift mixer so that it can be swivelled safely over the railings.
    NOTICE! The mixer must hang horizontal on the hoisting gear. If the mixer hangs at an angle to the hoisting gear, adjust the attachment point on the frame.
  2. Swivel the mixer over the basin.
    NOTICE! The frame must be perpendicular to the guide pipe. If the frame is not perpendicular to the guide pipe, adjust the reach of the hoisting gear.

  2. Insert the guide pipe in the frame without tilting.
    NOTICE! The guide rollers are in contact with the guide pipe.
  3. Version with quick-release axles:
    Lower the mixer until the frame is below the upper holder. Install the quick-release axles and plastic rollers and secure them with linchpins!

  1. Mixer mounted on the lowering device
  1. Slowly lower the mixer.
  2. Hang the connection cable on the lifting equipment using the cable brackets.
    The connection cable is routed safely using the lifting equipment (e.g. wire rope). CAUTION! If no cable brackets are used to route the connection cable, ensure that the connection cable is not pulled into the propeller!
  3. Lower the mixer to the end of the guide pipe or until it reaches the fixed limit stop.
  4. Secure the connection cable to the railing or hoisting gear to prevent it from falling!
  5. Check the swivel range of the lowering device.
    Check the entire swivel range of the lowering device. The mixer must not bump into any structures (fixtures, basin wall). CAUTION! If the full swivel range cannot be used, mechanically limit the swivel range!
  6. Set the desired angle and install a screw to secure the lowering device against further adjustments.
  1. Installation is complete. Lay the connection cable and make the electrical connection.

If a mobile hoisting gear is used, install a cable bollard at the edge of the basin:

  • Remove lifting equipment (e.g. wire rope) from the hoisting gear and secure to the cable bollard.
  • Secure the connection cable edge of the basin to prevent it from falling.

CAUTION! If the connection cable leads over the edge of the basin, beware of potential abrasion. Sharp edges may damage the connection cable. Bevel the basin edge if necessary!
