Overview
The disc brake packages are available in 3 models. 3,000 to 30,000 foot depth drilling rigs, workover rigs and tractor hoists. The packages consist of the hydraulically actuated caliper assembly, a hydraulic operators control assembly and a hydraulic power unit. The caliper assembly can include various numbers of service calipers and spring set emergency calipers per side, depending on rig requirements. Discs can be ordered as water cooled by internal water jackets, vane cooled discs or ordinary sold discs. The hydraulic power unit consists of the hydraulic pumps, accumulators and the caliper controls. It provides hydraulic pressure to the service calipers and the emergency calipers, allowing the operator to easily maintain smooth and precise block movement. The Drawworks Disk Brake System has dual oil resources, dual operators control circuits and separate accumulator systems. The service calipers of the left and the right brake discs are pressured by two independent circuits. If one circuit fails the other can still supply enough braking force. The dual control main operation valve controls the braking force of the service calipers. In the event of hydraulic pump failure, the accumulators can supply enough pressure for 5 or 6 brake stops. In addition, a back-up pump can be started to provide system pressure.

Advantages
Compared with traditional band brakes, the hydraulic disc brake system has many advantages. Greater brake moment, stable brake performance, less motion inertia of the brake pairs, consistent brake force under heavy loads, accurate and sensitive control, easier maintenance and greater reliability. Compared to most competitors disc brakes, the replacement and adjustment of the pads is quicker and easier, reducing downtime and reducing costs.

Functional Operations
Service Braking - Using the brake handle of the brake valve, the driller can control the pressure on the service calipers of the disc brake allowing accurate and precise control of the movement of the traveling assembly. Emergency braking - In the event of a failure in the hydraulic control circuit or loss of pressure, the emergency calipers are released, the springs actuate the calipers causing a controlled stop.
Parking Brake - To insure no block movement or if the driller leaves the control area, the parking brake valve can be actuated so that the emergency calipers are applied. This prevents any block movement, regardless of the status of system pressures.

Interface With Other Systems
The Drawworks Disk Brake System can be interfaced with our unique autodrilling system, and/or any of our patented line of block controlling systems. During drilling and tripping, combining a series 7500 disk brake with our autodriller that incorporates our unique "Rig Match" feature and our Traveling Block Controller (U. S. Patent Number 5,342,020) that incorporates "Soft Stop" and "Intelligent Crown - A- Matic" provides a complete solution to safe and accurate block operation during all conditions.
