1. Controlled by servo system, the drive motor adopts imported servo motor. 2. Suspension mode: the whole suspension up and down stroke is not less than 2.5 meters. Intelligent lifting device in the suspended state, with the function of self-balancing, the operator does not need to control the device itself and the handle, only need to control the workpiece can be light to achieve the workpiece rise, fall. The system will detect the weight of the workpiece in real time no matter the weight increases or decreases to keep it in balance. 3. Speed: The maximum speed of rising and falling is ≤15m/min, and can be limited below the maximum speed; the actual running speed in floating mode is determined by the continuous longitudinal force applied to the induction handle, the greater the force, the faster the running speed and vice versa. 4. Control: equipped with induction handle, induction handle internal components sealed and equipped with pressure (photoelectric) sensors, can feel the force signal in the vertical direction in real time to control the direction of operation and speed of the system up and down. Operation of the induction handle detects the operator's vertical operating force (≤ 10N); the size of the required operating force can be changed by adjusting the sensitivity of the induction handle. 5. The system provides mechanical limits. 6. The workpiece can be operated directly by hand without touching the handle in hover mode. After the workpiece is finished releasing, no additional switching is needed, the system automatically switches back to the induction handle state to prevent the system from sudden upward movement. 7. Intelligent hoist has power failure protection, when a power failure failure occurs, the equipment will be stopped in place by the fail-safe device, when the power is supplied again, until an operator activates again the equipment can run immediately without any delay, and all the saved settings of the equipment will not be lost. 8. Intelligent hoist has overload protection function, when the equipment in the load exceeds its rated lifting capacity will automatically protect, can not lift. Overload protection will start automatically, the lifting speed control will fail, and only the descending control will be allowed to ensure the work safety. 9. Intelligent hoist has anti-bounce function no matter in handle mode or suspension mode, when the load changes suddenly, the device will not deflect and bounce, thus reducing the potential for injury accidents. 10. The intelligent hoisting device has upper and lower mechanical limit, which can stop unconditionally when running to the highest and lowest point to prevent the heavy load from rushing to the top. 11. Intelligent hoist can be manually mechanical limit, the limit protection point is precise and reliable. 12. Intelligent hoist provides handle sensitivity adjustment (10 level adjustment). 13. The overall industrial protection level of the equipment ≥ IP 54 (waterproof, dustproof), safety certification in line with the European standard ISO 4301/1. 14. LED panel, double button operation, simple and convenient. 15. Intelligent hoist can change the speed at will by changing the operating force of the handle without any presetting, and can also set the rising and falling speed at the same time, so it is not limited by any working conditions. 16. Intelligent hoisting device has the function of personnel in place, when the hand suddenly leaves the control handle, the hoisting device immediately stops rising or falling, and does not allow the situation of continuing to rise and fall. 17. The display of the handle must be able to show the weight of the lifted object for the operator's reference 18. The operating handle can be rotated 360° for the convenience of personnel. 19. Configured with a single-chip integrated circuit control module, the module is installed with a fault indicator, which can quickly determine the cause of the fault when the device is faulty and quickly eliminate the fault.
