Electric Double Girder Overhead Crane 32ton Span 25m
An industrial lifting system consisting of parallel runway beams supporting a movable bridge with two main girders. Powered by electric motors, it features a trolley and hoist mechanism that travels along the bridge for precise load handling. Designed for heavy-duty applications, it offers higher lifting capacities (>10T), greater span capabilities, and improved hook height compared to single-girder designs. Typical components include end trucks, runway rails, wire rope/chain hoists, and programmable controls. Commonly used in factories, warehouses, and steel mills for efficient material movement with floor-space optimization.
Key features:
-
Dual load-bearing girders for enhanced stability
-
Electric drive systems (AC/DC) with variable speed control
-
Pendant/radio remote operation options
-
Safety devices (limit switches, overload protection)
-
Modular design for customization
1,Main Girder
• The bridge girder of crane girder is designed to the DIN specifications and can be engineered to meet other local codes and regulations.
• Both rolled structural shapes and welded plate box girder designs are used depending on design requirements.
• The span can be divided to several parts when span exceeds 12 meters, which is convenient for container shipment.
2,End Carriage
• The crane end carriages are manufactured from structural sections and are jig assembled to ensure alignment of bearings and axles.
• Dual motor bridge drives are optional. Other drive types are available upon request.
• Bridge to End Carriages connections are bolted.
• Bridge wheels are flanged with anti-friction bearings.
• Rubber bumpers are standard on all end trucks.
3, Control Panel
• Each crane is supplied with a pendant control as standard equipment, radio control are optional.
• Other types of controls such as cabin control, infrared, or pendant control station sliding on independant track are available.
• We supply inverter controls for the trolley and bridge motions.
• The electrical components are housed in electrical cabinets to suit the applicable environment.
4, C-track festoon
C-track and flat cable Festoon Systems suspended as standard equipment,for delivering power &control to mobile equipment in a safe, efficient and maintenance free method. The cable trolleys are well guided inside their C-tracks and protected against humidity, dust and icing. Cable trolleys not only deliver power and control to mobile equipment which has reciprocal motion but also support large quantities of data cables including optic fibres travelling independently from the moble machinery .
5, Lifting Mechanism Electric Hoist
Lifting mechanism: The lifting mechanism adopts European wire rope electric hoist or electric chain hoist, which has lower noise and higher working level. Use pendant control or wireless radio remote control.
