Crowd Booster

Higher tensile forces through synchronization of several winches - the principle is simple: the main winch (Kelly winch) is switched to support the crowd winch. The rope from the Kelly winch is attached to the multi-sledge. This produces almost double the amount of pull force.

Parallel operation for single pass method

For continuous flight auger, double rotary and full displacement drilling, the Kelly rope is reeved through an extraction device at the rotary drive in addition to the crowd rope. The Kelly winch runs together with the multi-sledge.

Your benefits:

  • The rope crowd system receives more pull force.
  • More even distribution of the load on the multi-sledge, and so higher protection for its guides.
  • Less wear and tear on the ropes.
