QD150T double girder overhead crane

The QD150T double girder overhead crane represents a core product within Chunhua Crane’s heavy-lifting portfolio, engineered for mission-critical material handling in demanding industrial environments. Designed for B2B buyers requiring reliable, high-capacity lifting solutions, this crane delivers a rated capacity of 150 metric tons and is built to withstand continuous operation in steel mills, heavy fabrication shops, power plants, and logistics hubs. Its primary strength lies in a robust, non-standard customizable design that adapts to specific facility constraints while maintaining compliance with international safety and performance standards.

Technically, the QD150T is configured as a double girder bridge crane with a standard span range of 7.5 meters to 31.5 meters, and a lifting height adjustable from 6 meters to 30 meters to accommodate varying building clearances and load requirements. The main structure consists of two main girders fabricated from welded box-section steel, designed in accordance with GB/T 3811 and FEM/DIN standards for fatigue resistance and structural integrity. The trolley is equipped with a heavy-duty hoist mechanism, and the crane can be specified for indoor or outdoor service, with environmental parameters such as ambient temperature range and power supply type indicated at time of order. Control options include pendant handle control, wireless remote control, or a fully enclosed cockpit operation room, with the operation room available in three configurations: separated, closed, or insulated, depending on the working environment. Platform entry to the control room can be arranged from the side, end, or top to suit plant layout. For electrical systems, buyers may specify Schneider or Siemens components as optional upgrades, ensuring compatibility with existing plant automation. Standard safety features include an overload limiter, a large-screen load display, and multiple protection devices such as emergency stop, limit switches, and buffer stops. An added buffer height for the trolley is incorporated to absorb end-of-travel impacts. All units are supplied with CE certification and CCC certification as required, and can be engineered to meet CMAA or other regional standards upon request.

This crane is deployed across a wide range of heavy industries where precise, safe, and repetitive lifting of oversized loads is essential. Typical applications include steel mills for handling molten metal ladles and coil stock, shipyards for moving plate sections and machinery, heavy equipment manufacturing plants for assembling large components, power generation facilities for turbine and generator maintenance, port and terminal operations for container or bulk cargo handling, and warehousing or logistics centers managing heavy palletized goods. The 150-ton capacity combined with customizable span and lift height makes it suitable for both new facility installations and retrofit projects where existing crane runways must be matched.

Chunhua Crane, founded in 2003, offers direct factory pricing that typically undercuts European brands by 30 to 50 percent, providing significant cost savings without compromising on structural quality or safety compliance. As an original manufacturer, we provide full engineering support for non-standard customization, including modifications to span, lifting height, control interface, and environmental sealing. All cranes are manufactured in our Hefei facility under ISO 9001 quality management, and we can supply CE, CCC, and other required certifications to facilitate import clearance. Our engineering team delivers a detailed quotation and preliminary CAD drawing within four hours of receiving a complete inquiry. With sea freight logistics established to over 60 countries, we ensure reliable delivery timelines and offer optional on-site installation supervision by our technical staff.

The ordering process is straightforward and designed for international buyers. Initial contact can be made via WhatsApp or email with your required capacity, span, lifting height, control preference, and any environmental or power supply specifications. Our sales engineering team responds with a firm quotation and preliminary CAD layout within four hours. Upon acceptance, a 30 percent T/T deposit is required to commence production. Standard manufacturing lead time is 30 to 45 days, depending on customization complexity. After production, the remaining 70 percent balance is due prior to sea freight shipment. We coordinate all export documentation and shipping logistics. Optional installation and commissioning services can be arranged at the buyer’s site, with our engineers traveling to provide training and handover.
