美国采购需求：真空管升降器

I am looking to source mobile lifting equipment with a maximum safe working load of 80 kg. Specifically, I am interested in lifters suitable for handling sacks and water bottles. It's important that the equipment is versatile and easy to use, as it will be employed in various operational settings. Please provide me with details on your available models that meet these specifications, including pricing, lead times, and any additional features that may enhance functionality. If possible, include information about safety certifications and warranty options. Looking forward to your prompt response!
