Key Components for Reliable Performance
Motor: The hoist motor features a taper-type rotor with integrated braking, offering high torque and enabling frequent operations without loss of performance.
Trolley: Assembled with top-class sealed ball bearings, the trolley's running wheels provide smooth horizontal travel and ensure durability even under heavy usage.
Gear Box: Specially treated gears in the hoist gear box offer superior wear resistance. Each geared shaft assembly is supported on ball or roller bearings to guarantee smooth, low-friction operation.
Wire Rope: The hoisting rope meets ISO export standards and is designed to prevent lateral slipping on the drum. With a safety factor of six on nominal breaking strength, it ensures reliable load handling.
Rope Drum: The grooved, seamless drum accommodates a single-layer winding of the rope and is mounted on ball bearings to minimize abrasion and ensure smooth operation.
Electric Control System: The system includes a contactor box, controlling switch, and cut-off limiter. Working voltages are available in 380V, 36V, or 24V for enhanced safety.
Rope Guide: The two-part rope guide fully encircles the drum, preventing the rope from uncoiling, even under no-load conditions.
Hook: The hook block is tested to 150% of full load before assembly, and the rope sheaves are protected with steel casting to enhance safety.
Testing and Quality Assurance
All CD Model hoists are tested at 125% of rated load, ensuring safety, reliability, and compliance with industrial standards. Each hoist is delivered with a test certificate, guaranteeing that it meets performance and safety requirements.
