Frequency-controlled Electric Hoist for Smooth Operation at Factory Loading Point

The use of variable frequency electric hoists at factory loading points can give full play to their advantages of precise speed regulation, smooth operation, energy saving and high efficiency. They are especially suitable for the core needs of "heavy object loading and unloading, precise positioning, and frequent starting and stopping" in loading scenarios.

The core advantage of variable frequency electric hoist at loading point：
Precise positioning, reducing cargo loss
The variable frequency system supports stepless speed regulation from 0 to rated speed (such as low speed 0.5m/min, high speed 8m/min). When the cargo approaches the carriage, it can switch to low speed and accurately control the position of the hook (such as placing parts in the corner of the container, aligning the edges when stacking), avoiding collision and falling of cargo due to excessive speed, especially suitable for loading fragile goods, precision parts or high-value goods.
Soft start and stop to reduce the impact of equipment and cargo
Traditional electric hoists will produce mechanical shock when starting and stopping (such as sudden tightening of wire ropes/chains, shaking of cargo), while variable frequency electric hoists can reduce wear on hooks, chains, and tracks through smooth speed transition (gradually accelerating from 0 when starting, and slowly decelerating when stopping), while avoiding displacement or collision of cargo due to shaking, extending the life of the equipment and ensuring the integrity of the cargo.
Adapt to variable loads and improve work efficiency
Frequency conversion technology can automatically adjust the output power according to the load weight (such as speeding up when lightly loaded and maintaining a stable low speed when heavily loaded), avoiding the efficiency waste of "fixed low speed even for light loads". For example: use high speed when returning with an empty hook (saving time), and use medium and low speed when hoisting full boxes of goods (ensuring stability), which improves the loading rhythm as a whole.
Frequent start and stop are more reliable and reduce the failure rate
The loading point operation is frequently started and stopped. The motor and brake of the traditional electric hoist are prone to heating or wear due to excessive instantaneous current. The frequency conversion system reduces the starting current (starting current ≤ 1.2 times the rated current, and the traditional electric hoist can reach 5~7 times), reduces the loss of motors and electrical components, and reduces the probability of failure shutdown. It is suitable for high-intensity loading scenarios (such as loading more than 50 vehicles per day).
Energy saving and safety double guarantee
Energy saving: The motor output power is distributed on demand during variable frequency operation, which can save 10%~30% energy compared with traditional electric hoists (especially under frequent start-stop conditions);
Safety: Equipped with multiple protections (such as overcurrent, overload, overvoltage, and stall protection), and the brake response is smoother during low-speed operation to prevent heavy objects from "slipping the hook", which complies with factory safety regulations.
