斯里兰卡采购需求：乘客电梯、安全电梯、家用电梯、货运电梯、高速电梯、观光电梯

I'm looking to gather more information regarding the elevator options you offer. Specifically, I need details on your available models, their specifications, and any unique features that set them apart. It would be helpful to understand their load capacities, speed variations, and the types of control systems used. Additionally, could you provide the pricing structure and lead times for different configurations? If there are any warranties or maintenance services included, that info would be great too. I'm interested in understanding how your products can meet our requirements and any recommendations you might have based on industry standards. Thanks!
