Structure

Structure

1. Mechanical Brake: A mechanical brake is provided in all Nitchi-Matic models. Used in combination with a solenoid brake, it ensures safe and thorough braking operation.
2. Solenoid Brake: Nitchi’s original direct-current solenoid brake is highly robust, effective, and durable.
3. Motor: Designed exclusively for use in electric chain hoists, this high-performance, high-torque motor can withstand frequent use over a long period of time.
4. Load Sheave and Chain Guide: Manufactured through high-precision machining and advanced heat treatment, the load sheave and chain guide together ensure smooth winding of load chains, thus contributing to their extended service life.
5. Over-Winding Protector: Equipped with a limit switch, the over-winding protector automatically shuts down the control circuit when the lifting or lowering operation has reached its limits.
6. Load Chain: Produced through an integrated manufacturing system under strict quality control, Nitchi’s super-strong and wear-resistant load chains made from special alloy steel achieve a high level of work safety. For work environments requiring highly corrosion-resistant chains, use of NN chains is recommended.
7. Negative Phase Protector: When three-phase power cables are connected in a negative phase, the control circuit is automatically shut off and lifting and lowering are disabled to protect the hoist from damage.
   Note: A negative phase refers to a situation in which two three-phase power cables in an electric chain hoist are reversely connected, thus causing the motor to rotate in the opposite direction.
8. 24V Low-Voltage Control Circuit: The control circuit is designed to run on low voltage to ensure work safety.
9. Oil Bath Lubrication System: By providing increased gear-cooling effect, this system allows a hoist to withstand frequent operation over a long period of time.
10. Bottom Hook: A built-in thrust bearing ensures smooth rotation of the hook.
11. Push-Button Switch: A small, lightweight, and highly insulated rainproof push-button switch is used. Two-speed models employ a dual-stage push switch.
