The double-beam trolley electric hoist is a new type of electric hoist with light weight, modularization, maintenance-free and high-tech content, which is completed by our company on the basis of introducing and digesting foreign technology, using imported configurations, new materials, and new processes. The lifting motor and reducer imported from Germany are adopted. The integrated compact design of lifting motor, reducer, reel and lifting limit switch saves the user’s use space. The modular design effectively reduces maintenance time and cost while enhancing the reliability of the mechanism. It has faster and more lifting speeds and a variety of pulley ratios to choose from.
