WANGLI Hand-Crank Study Set – Efficient Classroom Management with Modern Engineering
In a busy classroom, time is of the essence. WANGLI has engineered this hand-crank study set specifically to enhance classroom management efficiency. With its effortless hand-crank lifting system and clean, contemporary Blue & White design, this set allows teachers to adjust student workspaces in seconds, ensuring every child maintains perfect ergonomic posture without interrupting the flow of the lesson.
Features that Streamline Your Classroom:
Effortless Hand-Crank Height Adjustment: The desk (670-790mm) and chair (380-440mm) feature smooth, precision hand-crank mechanisms. A few quick turns are all it takes to perfectly align the furniture to a student's height, making transitions between grades or seating assignments completely painless.
Ventilated and Rugged Steel Storage: The 450*300*150mm storage box is crafted from 0.7mm galvanized steel. It is thoughtfully designed with perforated side holes to maintain airflow, preventing musty smells from developing in stored books. The box features a strong ABS hook and is engineered to handle a heavy 10KG load capacity without sagging.
Enhanced Structural Thickness: We utilize thicker 30*60*1.2mm oval steel tubes for the lower frames of both the desk and chair. This extra thickness provides superior resistance to bending and twisting, guaranteeing a wobble-free writing surface that stands up to even the most energetic students.
Comfort-Driven PE Seating: The 400*370mm seat and 400*220mm backrest are crafted via a single-cycle blow-molding process from high-quality PE. The contoured shape offers firm lumbar support, while the smooth, durable surface wipes clean in seconds.
Wear-Resistant Heavy-Duty Glides: The desk and chair rest on industrial-grade nylon accessories. With an abrasion resistance exceeding 100,000 cycles, these heavy-duty glides allow furniture to slide silently across floors without scuffing surfaces, protecting your long-term investment in quality flooring.
