The UNI-S550-L series integrated construction hoisting machine is a newly developed, industry-specific solution. It is designed for use in construction hoists and the lifting and hoisting industries. Featuring frequency conversion speed regulation technology, this system enables stepless speed control during the starting, acceleration, deceleration, and braking phases of the construction hoist. This reduces the impact on the mechanical system during startup and shutdown, improves the stability and comfort of the hoist during operation, extends its service life, and significantly enhances work efficiency.
