Feima Lifting has been deeply engaged in the lifting industry for many years, and its dual-luffing electric hoist specially designed for the water conservancy sector was developed precisely to address common challenges in gate operation, such as tilting, jamming, and asynchronous movement.

Unlike conventional hoists that rely on flexible couplings, the Feima dual-point hoist employs a rigid shaft coupling design. The two lifting points are mechanically synchronized via universal drive shafts, completely eliminating lift discrepancies caused by wire rope slippage or delays in the electrical control system. This ensures that gates weighing several to dozens of tons remain perfectly level at all times, thereby fundamentally preventing risks such as gate jamming, deformation, and seal failure.

In response to the humid, dusty, and corrosive conditions typical of hydraulic construction sites, the equipment features a fully enclosed protective design, with key components treated for rust and corrosion resistance. Paired with a high-strength planetary gear reducer and wear-resistant steel wire rope, it delivers maximum impact resistance, ensuring stable power output even under prolonged start–stop cycles and frequent operation, thereby significantly reducing long-term maintenance costs.

Multi-layered protection and a dual-braking system: in the event of a power failure, both brakes engage simultaneously to lock the mechanism, completely eliminating the risk of uncontrolled descent; dual limit switches at the upper and lower travel extremes prevent overtravel and over-discharge; overload protection: when the rated load is exceeded, the system automatically cuts power and shuts down, safeguarding both equipment and personnel. Each layer of protection serves as an additional safety measure to ensure the safe operation of hydraulic engineering projects.
