Cascade: Cascade Cascade with integral die-cast and assembled Cascade categories. ① overall Cascade Die Casting: As shown, the overall cascade system aluminum die-casting, pedals and start casting plate 6.7 has ribs, anti-slip function and role in guiding the adjacent Cascade. This cascade is characterized by light weight (about half the weight of the assembly-Cascade), high escalator design, visual quality, Xiajin County escalators, ease of manufacture, assembly and maintenance. ② assembled cascade: as shown in Figure 6.8, fabricated rung is composed of pedals, start plate, the bracket (above the die casting) with the base plate (stamping), rollers, etc., escalators custom manufacturing process complex cascade size and shape after assembly tolerances identity poor, heavy, not easy assembly and maintenance.
