Terms of Use
This website is operated by Hangzhou QSD Technologies Co., Ltd. ("QSD Technologies", "we", "us"). Dr. Elevage and 梯先知 are brands of QSD Technologies. By accessing or using this website you agree to these terms. If you do not agree to them, do not use the website.
Information only, not an offer. Content on this website is general product information. It is not an offer, quotation, warranty or contractual commitment. Specifications, features, compatibility and availability may vary by region and configuration and may change without notice. Binding terms apply only under a written agreement signed with us.
Acceptable use. You may browse and share pages for lawful, non-commercial purposes. You must not use the website for any unlawful purpose; interfere with its operation or security; attempt unauthorized access; or scrape, harvest or copy its content by automated means.
Safety & statutory obligations
Dr. Elevage is a monitoring and decision-support tool. It does not replace statutory periodic inspection, maintenance by a qualified maintenance contractor, emergency rescue arrangements, or any duty owed under applicable law and technical standards by the elevator’s owner, by the party responsible for operating it, or by its maintenance contractor.
Alerts, risk grades and reports are generated from sensor data and models and may be incomplete or inaccurate. Decisions on operating, stopping or repairing an elevator must be made by qualified personnel based on on-site inspection.
Case studies, data & statistics
Case studies describe specific deployments, with the measurements shown as recorded. Customer, site and personnel details are anonymized; some charts are reconstructions and are labeled as such. Results depend on the elevator, its condition and how it is maintained, and are not a guarantee of similar outcomes.
Industry statistics are drawn from the public sources named on the page and are provided as-is. Figures about our own deployments are approximate and may be updated.
