The entertainment facility part of the project is a 12-meter diameter large steel structure lifting stage, and the banquet hall of a five-star hotel is a multi-point and single-point crane equipment, which requires fixed-point positioning and precise positioning of all single-point cranes and integrated control of variable frequency speed regulation. The overall integrated control of the equipment is highly required. All the equipment has been in use since its opening at the end of 2016. No abnormal situation has occurred. The customer is very satisfied and firmly recognizes our product quality and service.
