Is synchronous lifting and dropping possible?

Yes, by custom designing the hydraulic pump station. Enhanced flow and power may increase the cost.

How much economical is manual operation?

Compared to hydraulic elevator dams, manual operation saves about 30%-40% of investment.

AI-Powered supplier vetting

SummaryBeijing IWHR Corporation is identified as a China-based state-owned manufacturer/factory and group corporation, with 148 employees and valid import-export licensing. It provides extensive customization, has introduced new products within the past year, and offers an SDK, indicating established development capabilities. ISO 9001 and ISO 14001 certifications, 50 quality-control staff, and documented procedures for supplier assessment, corrective actions, and complaint handling support its quality-management and service processes. The supplier has exported for 30 years and reports that exports represent 41%–50% of total sales. However, it reports no inventory capacity, overseas warehouse, overseas showroom, or ODM service, while environmental assessment, fire-drill status, and trade-volume information are unspecified. No explicit customer cases are provided.

Supplier typeThe supplier is described as a manufacturer/factory and group corporation, with a separate entry also identifying it as a trading company. It is a state-owned limited company based in Beijing, China, with 148 employees and valid import-export licensing; the mixed classification should be clarified during due diligence.

CertificationsThe supplier holds ISO 9001 and ISO 14001 certifications. These explicitly support quality-management and environmental-management system credentials.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints, as well as corrective and preventive actions, and it can provide services through overseas agents or branches. However, it lacks overseas warehouses and showrooms, so its after-sales infrastructure is documented but not comprehensive.

R&D capabilityThe supplier reports new products within the past year, has an available SDK, and has 21–30 years of total R&D-engineer experience. Its described activities also include R&D and system integration, providing explicit evidence of substantial innovation resources.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These repeated listings demonstrate broad customization coverage, although ODM service and OEM service for popular brands are not provided.

Product Q&A

Q:How does the hydraulic elevator dam operate?

Supported by two hydraulic cylinders at a small angle, powered by a hydraulic station using hydraulic oil to move the cylinder rod for blocking and discharging flood.

Q:What is the lift and drop time?

Lifting time is about 1min/m per gate. Lowering time can be adjusted between 30s and 30min.

Q:Can the water be blocked at any height?

Yes, the hydraulic elevator dam can achieve arbitrary dam height for water retention.

Q:How does the dam handle sedimentation over 30 cm?

It is designed to withstand severe mud and sand. It can adjust to a 75-degree vertical angle to wash away sedimentation under normal flow conditions.

Q:What if branches and stones get stuck in the dam?

Floating objects drift away with water flow. Stones stuck between surfaces can be released by adjusting the dam's angle to use gravity and water flow.
