Structure of SCD250/250 Building Lifter Description
To serve the increasing demand for highrise construction, we developed the high speed VF hoist, with a max.lifting speed of 96 m/min.
It has the following structure:
1. Adopts the most advanced VF speed control device and microcomputer programmable logic controller.
2. Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process, and ensures automated leveling.
3. Adopts open loop V/F control: the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoids slipping during downward stopping of hoist.
4. The VF system has current-restriction function, ensuring a small current when motor start up and reducing the concussion to power supply. It reduces the energy consumption and mitigates effects to on site electric equipments.
5. The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack,pinion and the brake and prolongs the spare parts'life.
6. The VF system also has the over voltage protection, low voltage protection, overcurrent, overload and anti-stalling protection functions.
7. The System applies the special software for hoists developed by our company, making the operation more safe and reliable.
