Yes — we are a manufacturer with our own engineering team. You just need to provide all required specifications and we will design and build a custom crane solution tailored to your needs.

It depends on your practical application, workshop conditions, lifting requirements, and budget. We recommend contacting our sales team with your facility drawings and requirements — they will recommend the most suitable crane type and configuration.

For overhead and gantry cranes: span, lift height, capacity, material to lift, indoor/outdoor use, speeds, environment, usage frequency, and workshop drawings. For jib cranes: arm length, rotation degrees, lift height, and similar factors. The more details you provide, the more accurate your quotation will be.

Yes. If the ground concrete width exceeds 20cm, there is no need to excavate. Simply pave a belt steel plate, bolt it to the cement floor, and weld the rails on top. This avoids structural modifications to your existing facility.

For operations below -20°C, we use Q345 steel plate for enhanced low-temperature toughness. For high-temperature environments, we use H-grade motors, higher-grade insulation cables, and improved ventilation systems to ensure reliable performance.

By changing the connection method between the main beam and end beam, we can reduce the overall crane height. Alternate design configurations can further minimize the crane's profile to fit within limited headroom constraints.

Hoists use an automatic painting line. For large cranes, we apply two coats of epoxy polyamide primer and two coats of top paint, ensuring excellent corrosion resistance and long-term durability.

Yes — as a full manufacturer, we provide all matching spare parts including motors, hoists, drums, wheels, grabs, hooks, rails, travel beams, bus bars, and more.

Three operation methods are available: pendant push button control, wireless remote control, and cabin operation. The choice depends on your application requirements and operator preference.

Our cranes are equipped with comprehensive safety systems including: loss of voltage / phase failure protection, over-voltage / over-current protection, overload limit switch, weight limit monitoring, hoist up/down limit protection, and crane travel limit switches.

Yes — we offer various lifting attachments including clamshell grabs, orange peel grabs, electromagnets, C-hooks, belt slings, and other custom attachments tailored to specific handling needs.
