How the SiloWhip System works

Silo cleaning dates back to the time the first industrial silos were built. After a period of time, the material inside the silo tends to bond or harden due to the presence of moisture or contact with “foreign” environmental elements. It then starts forming a build-up along the sidewalls and at the base of the silo. This build-up continues to propagate, and as the years progress without proper maintenance, the situation leads to significant problems:

  • The layer of build-up that is formed over the prolonged period reduces the actual capacity of the silo. There are two specific areas where the build-up generally occurs:

    1. Sidewall of the silo – The layer of build-up, which bonds onto the sidewalls of the silo, begins to thicken. This symptom is known as coating or overhang if the layer becomes too massive.

    2. Base of the silo – The build-up forms at the base of the silo along the cone and sidewalls. The build-up becomes more compact and harder at the bottom as it stacks up higher. This is known as a hill formation. When a hill formation becomes too high and starts to join other hills, the effect known as bridging occurs.

The SiloWhip System is powered by hydraulics and controlled from the top of and outside the silo, which eliminates the need for people to enter the silo. With Health and Safety in mind, this method is the a safe alternative when performing silo cleaning without entering the silo.

The whipping head is suspended inside the silo, but operated remotely from the silo top, the silo whip efficiently clears build-up using an air-driven or hydraulic rotary cutter, with a 360 degree rotation and an operating depth of up to 50 meters. A range of cutters are used depending on the type of material to be cleaned. Cleared material simply falls to the base of the silo for extraction.


SiloWhip System - The most powerful whip in the world.

The SiloWhip System was purposely build for the Cement Industry. While it is well capable of handling build-ups in silos containing other material, nothing is more challenging than breaking down the hardened material found commonly in cement or clinker silos.

  • Pure Power

    The SiloWhip System is a FULLY HYDRAULIC system conveniently powered by a 3-phase, 380V electrical supply. It is all TORQUE and PURE POWER that sets the SiloWhip System apart from conventional air-powered whips.


  • Super Strength

    The key components of the SiloWhip System is made from a special grade of aluminum. This high-strength, light-weight material ensures that the SiloWhip is both durable and capable of any challenge inside a silo.


  • Work Remotely, Work Safely

    Once the SiloWhip System is fully assembled, it is operated safely at the top of the silo by using the Remote Control Unit (RCU). The RCU manages functions such as lowering and lifting the boom and whip unit, changing the direction of the whip rotation as well as adjusting the speed of the rotating whip.


  • Modular Design

    The SiloWhip System is designed to be extremely portable and easy to setup. It takes minutes for the SiloWhip System to be ready and equally fast for it to be packed and stored.


  • Ease of Maintenance

    Very little maintenance is required as the SiloWhip System is build to industry standard requirements. Proper care and handling will ensure that the whip works for you every time.


  • Wide Industry Applications

The SiloWhip System is built to breakdown materials ranging from a wide scope of industries such as:

  • Cement
  • Agriculture
  • Lime
  • Pulp & Paper
  • Power & Gas
  • Metal & Mineral
