Product DescriptionHigh-Performance General purpose overhead craneGeneral Purpose Overhead Crane is a versatile bridge - type lifting equipment. It integrates a bridge structure (composed of main and end girders), a trolley, operation mechanisms, and an electrical control system. Capable of handling diverse loads via attachments like hooks, grabs, or magnetic chucks, it covers lifting capacities from 3.2t to over 320t, spans 7.5 - 31.5m, and offers lifting heights of 6 - 30m. With precise variable - frequency speed regulation, multiple safety protections (overload limiters, stroke limiters, etc.), and a durable steel structure, it suits manufacturing, metallurgy, and warehousing. It supports high - frequency material handling, can be customized for explosion - proof, intelligent, or special - environment applications, ensuring efficient and safe material transfer in industrial production.SpecificationApplicationsIndustrial Handling: Heavy machinery lifting, equipment installation, component transportation.Warehousing: Palletized goods handling, inventory stacking, storage retrieval.Construction Material Handling: Steel beam hoisting, precast concrete lifting, building material transfer.Port Operations: Container handling, cargo loading and unloading from ships.Manufacturing: Assembly line material transfer, large part positioning, production equipment movement.Power Plants: Turbine component installation, boiler part handling, coal - fired power plant material transportation.Shipyards: Hull section lifting, ship machinery installation, vessel component assembly.Recycling Facilities: Scrap metal handling, large waste item sorting, recycling material transportation.Metalworking Industry: Heavy metal billet and ingot handling, finished metal product movement, stamping press material feeding.Railways: Locomotive and railway car component handling, track laying equipment movement, railway bridge construction material hoisting.Key ConfigurationsEngine (if applicable): Electric motor drive system with variable frequency control for energy - efficient and precise speed regulationLifting Mechanism: High - strength wire ropes and durable hoist drums for reliable load liftingBridge Structure: Robust steel construction with optimized load - bearing capacity and stabilityTrolley System: Smooth - running trolleys with adjustable travel speeds for horizontal movementControl System: Advanced remote control or cabin - based control panel with load - weighing and anti - sway functionsSafety Features: Overload protection devices, emergency stop buttons, and limit switches for enhanced operation safetyDrawings & DimensionsOur engineering team can provide tailored designs to meet specific project requirements.Detailed Technical SpecificationsCustom configurations available upon request for tailored solutions.ItemQD Double-Girder Overhead CraneLD Single-Girder Overhead CraneTechnical Notes / Application SuggestionsApplicable ScenariosHeavy industry, metallurgy, large assembly lines, energy equipmentWorkshops, warehousing, auxiliary lifting, light-duty material handlingQD is suitable for frequent, heavy-duty, high-intensity usageRated Lifting Capacity5t ~ 320t (customizable)1t ~ 20t (customizable)QD supports a wider capacity range for large loadsSpan Range7.5m ~ 40m7.5m ~ 31.5mBoth support customization to match workshop layoutLifting Height6m ~ 30m (extendable)6m ~ 20m(extendable)Customized based on lifting requirementsLifting Speed5~15 m/min (based on capacity and hoisting type)8/0.8 m/min or 7/0.7 m/min (dual-speed CD/MD hoists)QD adopts rope drum hoists with customizable speed controlTrolley Speed20~40 m/min (VFD optional)20 m/min (standard)QD has independent trolley drive for smoother travelCrane Travel Speed40~100 m/min (often VFD-equipped)20~30 m/minQD supports higher speed and large-span transfer efficiencySpeed ControlVFD / fixed-speed options, soft start supportedMostly fixed speed, some dual-speed or basic VFDQD supports precise control;
