Electric Freight Elevator

Electric Traction for Goods Movement
The DH2000/0.5-VF uses electric traction and is rated for 2000 kg at 0.5 m/s. During repeated transfers between storage and working floors, the drive moves the loaded car through the hoistway without a hydraulic lifting cylinder. There is no hydraulic lifting circuit to refill or drain as part of that drive arrangement.

Machine-room-free Installation
The traction machine and associated control equipment are accommodated within the hoistway arrangement. On a project without a dedicated rooftop machine room, this places the drive equipment within the elevator installation envelope. The building layout therefore does not need a separate machine room for this configuration.

Permanent Magnet Drive
A permanent magnet synchronous motor uses permanent magnets to establish the rotor field. During repeated goods-transfer runs, the motor requires no electrical power to excite a rotor winding. This avoids the associated rotor copper losses while providing traction torque for the loaded car.

Dongao adapts its modular elevator design to the building's shaft drawings and landing arrangement. The project configuration is established from the measured installation space, floor sequence and goods route, then manufactured to the confirmed technical drawings. Car, entrance and control layouts are coordinated as a complete assembly. OEM and ODM production is available for project-specific equipment supply.

Customizable Items

• Car width, depth and height
• Entrance width and height
• Landing positions and floor designations
• Entrance position and opening arrangement

Quality traceability covers incoming materials, manufacturing and dispatch. Acceptance for an electric freight lift focuses on the identity and assembly of the drive and control components, the electrical connections and agreement with the approved wiring documentation. The manufacturer applies self-inspection, mutual inspection and specialist inspection across the work stages.

Every elevator is inspected before packing, and third-party inspection is accepted. The installed equipment undergoes a separate project acceptance stage after connection in the actual building. That stage addresses the completed electrical and mechanical installation before the lift enters normal goods service.
