TJ2 Series: Cost-Effective Electromagnetic Safety Drum Brake

TJ2 series electromagnetic drum brake is an economical spring-closed safety braking device driven by AC electromagnet. Unlike electro-hydraulic and pneumatic brakes, it only relies on alternating current power supply to realize braking release, without supporting hydraulic stations, thrusters, air compressors and complex pipelines. With simple structure, low procurement cost and easy electrical control, it is widely matched with small electric hoists, mini overhead cranes, workshop winches and light-duty conveying equipment. When power is cut off, the built-in spring instantly clamps the brake drum to prevent load falling and equipment sliding.

Core Competitive Advantages

Ultra cost-effective, save auxiliary system investment (Core highlight)Integrated electromagnetic drive design removes extra supporting equipment such as hydraulic oil cylinders or air compressors. Lower overall purchasing cost and simplify on-site layout. Perfect choice for small factories and light-load equipment renovation projects with limited budget. Fewer wearing components greatly reduce long-term spare parts replacement expenditure.

Independent electrical drive, no medium auxiliary systemDirectly powered by AC power supply, no hydraulic oil leakage, pipeline blockage, air pressure loss and other common faults of hydraulic/pneumatic brakes. Simplify wiring and installation steps, greatly shorten construction cycle of production lines.

Fail-safe power-off locking safety designSpring-applied structure ensures instant braking once power fails or circuit trips. Reliable static holding torque locks hoist drum firmly to avoid cargo falling, providing essential safety guarantee for light lifting operations.

Fast response & accurate positioningElectromagnet produces strong instantaneous suction after power on, quickly pulling open brake shoes for equipment operation; short braking response time enables precise stop positioning for small workshop handling machinery.

Low daily maintenance workload

Standard equal-clearance linkage mechanism reduces frequent manual gap adjustment;

Snap-in plug-type friction linings can be replaced rapidly without disassembling the whole brake frame;

Self-lubricating hinge bushings eliminate regular greasing maintenance;

Simple integral structure, easy daily inspection and fault troubleshooting.

Flexible matching & customized optionsComplete specifications covering TJ2-100 / TJ2-200 / TJ2-300 to match different light load torque demands. Flameproof electromagnetic versions can be customized for small chemical workshops and underground mine light machinery. Dustproof outer covers are optional for high-dust cement and grain processing plants, vertical mounting as standard configuration.
