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.
During drilling and above all when extracting, the control system monitors that the crowd winch and the Kelly winch run at matched speeds and with the correct distribution of pull forces. The ropes on the winches are always taut so avoiding slack rope.
It also takes the burden of the operator. The automatic control function for both winches is activated by pressing a button on the joystick.
