Features

1.Dual Trolley Design: Equipped with two independent trolleys (configurable with the same or different lifting capacities) that can operate separately or synchronously. It is especially suitable for lifting long, large, or irregular workpieces, avoiding tilting and ensuring stable lifting. 2.High Customization: Fully customizable according to customer needs, including lifting capacity, span, lifting height, running speed, control method, power supply, and working environment. It can be tailored to match the specific layout and production requirements of the workshop. 3.Stable & Reliable Performance: Adopts double-girder structure, which has strong bearing capacity, good rigidity, and small deformation during operation. The core components (hoist, reducer, motor) are of high-quality brand, ensuring long service life and low failure rate. 4.Multiple Control Modes: Optional pendant control, wireless remote control, or cab control, adapting to different operation scenarios. Wireless remote control supports long-distance operation, improving safety and operational convenience; cab control provides a clear view for precise operation.
