Both DR and HHBB electric hoists are chain-type, but they also differ. DR is an upgraded product based on the HHBB model,
There are seven major advantages.
First, the housing adopts a one-piece cast aluminum structure with a streamlined design, ensuring both aesthetic appeal and an IP55 protection rating, offering superior dustproof and waterproof performance.
Second, DR focuses on high performance, featuring lower noise, reduced vibration, and faster lifting speeds.
Third, it is equipped with an external cooling fan motor and heat sink for better heat dissipation.

    Fourth, the work level reaches M5 (load state + utilization grade), capable of meeting the high-intensity demands for long-term stable operation.
Fifth, equipped with an electromagnetic brake, it can achieve emergency braking to prevent falling hazards and enable the stable hovering of heavy objects at the target height, ensuring precise lifting.
Sixth, the dual-axis connection design paired with a sports car ensures smoother operation of the electric hoist and enhances positioning accuracy.
Seventh, adopt eco-friendly design to achieve lower energy consumption and more cost-effective long-term usage.
