Product Description
Industrial hoists, overhead cranes, and mining winches require fail-safe braking mechanisms to protect personnel and heavy cargo. Jiangsu Sanzhong Elastic Technology Co., Ltd. is a leading supplier of heavy-capacity Disc Spring Stack assemblies used in emergency caliper brakes and rail clamps. Our spring stacks act as the primary mechanical energy storage element, instantly engaging the brake pads whenever hydraulic pressure or electrical power is lost.
Because emergency brakes can sit idle for long periods before being called upon to deliver immense force, resistance to stress relaxation (creep) is vital. Our engineering processes ensure that our disc spring stacks retain their stored energy over years of standby operation without losing load capacity. This reliability provides emergency braking systems with the constant force required to bring massive kinetic loads to a safe, controlled stop.
- Overhead Gantry Cranes: Installed in main hoist emergency disc brakes to prevent load drops during power interruptions.
- Port Container Handling Equipment: Integrated into storm brakes and rail clamping systems to secure heavy machinery against high winds.
- Mining & Conveyor Systems: Applied to high-torque drive conveyor systems to facilitate controlled deceleration and emergency braking.
- Material Integrity: Heavy-gauge 51CrV4, 60Si2Mn, and custom alloy formulations optimized for thick-section spring elements.
- Thickness (t) Sizing: Capable of processing thick plates from 2.0 mm up to 50.0 mm per individual disc.
- Max Static Load Capacity: Scalable stack configurations delivering forces exceeding 2,000 kN.
- Corrosion Protection: Advanced surface coatings including Geomet, Dacromet, electro-galvanizing, or epoxy powder coating for outdoor maritime exposure.
- Quality Verification: Each stack undergoes mandatory presets (scragging) to zero out initial setting losses before shipping.
