Metallurgical and mining workshops have high dust and load, and equipment needs to hover and lift for a long time. Hydraulic lifting is prone to oil leakage and pollution of workpieces, while screw elevators are purely mechanically driven and have no risk of leakage, making them the preferred choice for heavy-duty lifting. The gap adjustment of the rolling mill in the steel rolling production line, the lifting of the steel coil bracket, and the opening and closing of the heating furnace door all use large tonnage trapezoidal screw rod elevators. Each unit can carry tens of tons of heavy objects, and the fully sealed structure of the box body prevents iron filings and dust from entering, extending the service life of the transmission components. The fine adjustment of the feeding port of the mining crusher, the lifting of the heavy-duty maintenance platform, and the lifting of the discharge gate rely on the self-locking characteristics of the screw rod. After stopping, the load will not slide, eliminating the need for additional braking accessories; The water conservancy channel gate and steel plant dust removal baffle opening and closing mechanism operate in a dusty outdoor environment year-round. The anti-corrosion screw lift can operate stably and continuously, reducing on-site safety hazards
