Is it possible to lift and drop the dam at the same time?

Yes, we can custom design the hydraulic pump station to achieve synchronous lifting and dropping. However, enhancing flow and power to accommodate this will increase the cost.

How much more economical is the manual operation option?

Compared to the hydraulic elevator dam, investment will save about 30%-40%.

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?

The back side is supported by two hydraulic cylinders at a small Angle, powered by a hydraulic station. Hydraulic oil moves the cylinder rod to realize blocking and discharging flood.

Q:What is the lift time and drop time?

The lifting time of a single gate is about 1min/m, and the lowering time can be adjusted in 30s-30min.

Q:Can the water be blocked at any height?

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

Q:How does the dam work if sedimentation on top of its surface is more than 30 cm?

It is designed to withstand severe mud and sand sedimentation. The dam can adjust up to a vertical angle of 75 degrees to wash away sedimentation. Any remainder is not significant enough to affect lifting or dropping.

Q:What should be done if branches and stones are stuck in the dam?

For floating objects like branches, regulation of a single dam or coordination with adjacent dams allows them to drift away. If stones are stuck, the dam's angle can be adjusted to release them due to gravity and water flow.
