MATTCO Bear Cat Twin-stop

The Bear Cat Twin-Stop is the premier safety device that sets the brake to stop the drawworks motion in both directions. It engages the drawwork’s brake automatically, in either direction, at pre-set points. As a result, it protects both the rotary floor and the crown block. The Twin-Stop also incorporates a brake set valve which sets the brake and disengages the clutches immediately on command, regardless of the position of the traveling block.

FEATURES:
• A check valve is used to prevent the brakes from releasing due to loss of rig air supply
• The brake override valve, operated from the drilling console, permits the traveling block to move beyond the preset stops for special operations such as resetting the system or making a connection
• It is the only system that provides positive, reliable, automatic protection against equipment damage by the drawworks.
