The customization of hydraulic elevators requires consideration of actual usage needs and site conditions. Generally, the following steps can be referred to:

1. Clarify the specific requirements for dimensions (large load capacity, height), operating speed, and climbing time. These factors will directly affect the cost and maintenance cost of elevators. It is recommended to choose experienced designers or design companies for scheme design and consult relevant personnel for guidance on installation and commissioning;

2. Choose the appropriate type of drive mechanism, including turbine worm and gear rack forms, which need to be considered based on factors such as usage environment and load capacity;

3. After confirming that there is no harm, relevant information can be submitted to the manufacturer for filing and discussion on the detailed pricing of the product. This requires considering whether the budget is sufficient and paying attention to maintenance costs in the later stage, which is also one of the factors to be considered;

After passing the acceptance inspection, sign the agreement and ensure that all facilities and equipment meet the standards and are easy to operate.

I hope the above information is helpful to you. You still need to contact personnel or merchants to communicate and understand the specific details of the situation.
