When assessing the price of facade cleaning equipment, you must look beyond the sticker price and evaluate load capacity (typically 630kg to 800kg), lifting speed (8-10 m/min), and motor power (usually 1.5kW to 2.2kW). High-end models often feature hot-dip galvanized steel or aluminum alloy platforms which offer superior corrosion resistance, justifying a higher initial investment compared to painted steel. Ensure the equipment includes a reliable hoist system (e.g., LTD series) and a safety lock (e.g., LSF series) to prevent tilting or falling.
