The hoisting system guide device installation and removal service is a precision engineering solution for the head sheave (guide wheel) assembly of equipment such as mine hoists, aerial passenger devices, and endless rope winches. The service covers the entire process of old wheel dismantling, bearing replacement, new wheel hoisting and positioning, axial laser alignment, and dynamic tension balancing of multi-rope systems. Utilizing intelligent hydraulic lifting devices, high-precision laser alignment instruments, and wireless tension monitoring systems, it achieves guide wheel installation with radial deviation ≤0.1mm and axial inclination ≤0.05°, while simultaneously completing wheel leveling correction and wire rope groove entry optimization. Compared with traditional methods of hammer alignment and experience-based adjustment, alignment efficiency is increased by four times, and the wheel replacement cycle is shortened by over 50%. It completely eliminates risks of high-altitude heavy component lifting collisions and wire rope eccentric wear, extending wheel train service life by more than 30%. This service is widely applicable to main and auxiliary shafts in coal mines, belt conveyor transfer stations, and various mining transportation systems, and can be extended to the operation and maintenance of heavy-duty guide structures such as port ship unloaders, large cable car ropeways, and tower cranes. With a closed-loop delivery of "dismantling-installation-calibration," it provides customers with long-term, reliable operation of hoisting systems characterized by low vibration, low wear, and high reliability.
