The JM series is mainly designed for heavy-duty lifting and pulling at slow and steady speeds. It is commonly applied in construction projects, bridge and road engineering, mining, factories, and ports for handling heavy materials, installing equipment, and moving large structures.

Low-speed operation provides smoother motion, greater control, and enhanced safety for heavy lifting. It reduces wear on the wire rope, minimizes shock loading, and ensures precise positioning during installation work.

JM winches are equipped with reliable brakes, overload protection, and orderly rope winding systems to prevent accidents. Optional features include limit switches and dual-speed control for added safety and flexibility.

Yes. Users can request specific lifting speeds, rope lengths, drum sizes, and motor power ratings. Custom designs are available to suit different industries and working environments.

Consider factors such as maximum load capacity, rope length requirements, working environment (construction, mining, marine, etc.), and available power supply. For frequent or precise lifting tasks, a variable frequency drive (VFD) can be recommended for better control.

You should consider your crane type (single rope, double rope, four rope, or hydraulic), lifting capacity, material type and density, working environment, and operational frequency. Our engineers can assist you in making the best choice.
