INTRODUCTION
1. Connected in series to a motor circuit, a Current Driven
Electromagnetic Brake does not release unless the motor is
energized. This concurrent drive increases safety of the circuit
compared to separate circuits for the motor and the brake.
2. Uniquely-structured Chain Guide for smooth chain-feeding.
3. Tough body is made by Die-Cast Aluminum to keep dimension
precision & outlook smooth..
4. External motor fan.
5. Thermal Protector Sensor overheating to shut off the current.
6. Friction Clutch Emergency overload protection to slip the force from
the motor when subjected to an excessive load over the rated
capacity. It is not easily compromised with changes in the
surrounding temperature. In the case of irregular loading, this
operates in advance to prevent the hoist body or load chain from
being damaged.
7. Grind Helical Gears reduces operating noise.
8. IP55 Enclosure Dust-protected and jet protected.
9. Absolute Safety Hook Equipped with a bearing & characterized by
gradual elongation, not sudden breakage under overload conditions.
The notched latch for firm contact improves resistance against lateral
force.
10. Rubber Cushion Buffer.
