Product Overview: disc brakes widely used in large and medium-sized cranes, port handling machinery, lifting, tilting mechanism low speed shaft emergency safety brake. Yang is the volume, mine hoist brake safety device indispensable. Product Features: designed by NC, is de-energized - Safe brake design is reasonable, the dish spring force, smooth and reliable hydraulic loose valve, hydraulic braking torque with a manual override device large, responsive friction material international brand names and seals are more than 0.45 coefficient of friction braking force large and stable, long life factory with limit switch interlock and wear tips. In addition to the above characteristics of the brake also has the following: multi-cylinder braking, greater clamping force 500KN can adjust the braking torque of instant noodles, between brake pads and brake disc replacement brake pads convenient distance for both the original use of the brakes customers (including Shanghai Zhenhua Port Machinery) to provide spare parts.
