I'm looking for a lift system with specific dimensions and capacity requirements. Ideally, the shaft dimensions should be 1800mm in width and 1500mm in depth. The floor and overhead height should both be 2850mm, with an additional pit depth of 1500mm. The capacity needs to support up to 480kg, accommodating a 5-stop design with 5 openings. Please provide details on the available options that meet these specifications, including lead times, pricing, and any additional features or configurations that may be beneficial. Your prompt response will be appreciated.
