SZZ (SZB) series scraper loader creatively replaces conventional welding and casting welding chutes with integral casting non-welding chutes, which doubles the overall service life, greatly reduces production and use costs, and improves working face transportation efficiency.
The tensile strength of the whole casting chute in the conveying part is ≥1200MPa, the hardness is ≥40HRC, and the wear resistance is twice that of the imported NM400 wear-resistant plate. Compared with the welded structure loader, the use efficiency and life of the product are greatly improved.
Technical Features
High strength, high wear resistance
The conveying chute adopts new materials and new technology, with high overall strength and high wear resistance.
Energy saving
The middle plate of the conveying chute adopts a corrugated structure design to reduce frictional resistance and save energy and reduce consumption.
low failure rate
Since the conveying chute completely adopts the integral casting technology, the problems of welding, falling off of the middle and bottom plates, and inconsistent wear resistance between the groove and the middle plate are avoided during use. , improve production efficiency and reduce production costs.
Production characteristics
Customized according to customer requirements.
Delivery period
The traditional manufacturing takes 2 months, and the whole casting production takes 40 days. The quality is reliable, the supply is timely, and the demand is met.
