1. Key safety features: multiple protections
Dual brake system: This is one of the most important safety measures. Usually includes:
Mechanical (load) brake: Normally closed design, relying on spring force braking, electric release. Even if the power is off, it can automatically brake the load to prevent falling.
Motor (electromagnetic) brake: Auxiliary braking, providing faster and smoother braking response.
Upper and lower limit switches: Accurately control the limit position of lifting and lowering to prevent the chain from over-rising (topping) or over-falling, protecting equipment and personnel safety.
Overload protection (some models): Some mid-to-high-end models will integrate mechanical or electronic overload protection devices (such as friction clutches or electronic sensors). When the load exceeds the rated tonnage (such as 110%), it can automatically cut off the power supply or slip to protect the core components of the hoist from damage.
Phase sequence protection (three-phase electricity): Prevent the control direction from being wrong due to the reverse phase sequence of the power supply.
Emergency stop button: There is a striking emergency stop button on the flashlight door, which can immediately cut off the power supply in an emergency.
Chain bag/chain guide device: Ensure that the chain is smoothly and orderly retracted and released to prevent the chain from twisting, getting stuck or injuring people.
2. Environmental adaptability:
Protection level: Standard models usually have IP54 protection level (dustproof and splashproof), which can adapt to most indoor industrial environments. There are also higher protection levels (such as IP65/IP67) or explosion-proof models to choose from.
Working level: The common working level of 1-ton chain hoists is M3 or M4 (divided according to the frequency of use and load rate), which is suitable for medium use intensity. When purchasing, you need to choose the appropriate working level according to the actual working conditions (daily use time, number of starts and stops per hour, average load rate).
Lifting Motor:
Power & Performance
Rated Capacity: 1tons (compatible with standard 220V/380V or customized voltage).
Duty Class: S3 (15-40%) – Suitable for intermittent operation with frequent starts/stops.
Insulation Class: F-grade (heat-resistant, ensuring long service life).
Speed Control Options
Single-speed: Standard fixed-speed operation (e.g., 6.6 m/min).
Dual-speed: Dual-winding motor for precision lifting (e.g., 2.2/6.6 m/min).
Optional VFD Control: Smooth acceleration/deceleration for sensitive loads.
