All kinds of single girder bridge crane
Bridge Steel Structure Part

Single girder overhead crane bridge frame consisted of main girder and end girder. End girder device including traveling motor, reducer, driving wheel set, rubber buffers and other components.
Main Girder
Main beam is the main carrier member of Single Girder Overhead Crane; the lower flange is hoist traveling track. Its structure made by steel rolling into U-shaped groove, oblique cover plate, ribs and I-beam welding into plain girder or with steel plate welding into box girder, two ends of the beams have board connections. Main girder made ​​into upper arched as required, arch degree not less than horizontal under the rated weight, without permanent deformation during normal working.

End beam device
End beam is located in Single Girder Overhead Crane main beam ends, bolted by clevis and main girder, Its structure made by steel rolling into U-shaped groove, oblique cover plate, ribs and I-beam welding into plain girder or with steel plate welding into box girder.
Single Girder Overhead Crane End Beam and Main Girder
 A one-time processing the wheels axle hole and the gear output shaft hole via a special purpose machine, fully guarantee the machining accuracy. Both bottom sides of the beam middle clevis settled hand hole peg board for easy removal and installation of the main or side beams. Both ends of the side beams mounted rubber buffers, can avoid the structure due to collision damage. Between end and main beams using high-strength bolts with shear hanging connecting structure, it is simple, easy to install, easy transportation and installation. When loading weight or span is large, the main end beam adopt seat structure to connect, part of the main beam ends is mounted on the end beam, main beam end with vertical plate and horizontal connect plate fixed connected integrally by bolts and end girder.

Driving Unit
Driving box and cover is cast from good anti-vibration performance gray iron HT200; after aging treatment through special fixture processing and manufacturing on the lathe.Gears and gear shaft material is 40Cr, after a series of precision machining by machine tool, heat treatment hardness is 235-269HB.
Single Girder Overhead Crane Driving Unit

Motor adopt soft start motor, can start with stability from slow speed to normal speed, solved impact operation compared to the normal motor, it is for frequent start, energy saving and environmental protection. Standard Motor insulation class is B, protection class IP44, also can made ​​to F, H insulation class, IP54, IP55 protection class according to working conditions requires.
Single Girder Overhead Crane soft start motor                    Single Girder Overhead Crane Wheel set
Wheel set made ​​of 45 # steel, made after ​​precision machining by the machine tool and heat treatment, heat treatment hardness 300-380HB, hardened layer not less than 260HB at a depth of 15mm.
Wire and Cable
The crane all use copper, stranded, insulated wires and cables with sheath.
The crane cable laying at trunking or steel pipe with wall thickness of 1.5-2mm. Installed with protective devices in the part of mechanical damage, chemical corrosion or oil erosion.
Electrical generally use CHNT Electric, Mitsubishi, Yaskawa, Siemens, Schneider and other brands.
Single Girder Overhead Crane Electrical Systems
Electrical Protection Systems
Short circuit protection
The total power circuit set up automatic air switch to protect crane short-circuit; Control circuit setting small capacity automatic air switch as short-circuit protection.
Emergency power-off switch
Crane set with red mushroom head type rotary reset emergency power off switch for emergency situations quickly cut off the main power and control circuit of the crane. Emergency off switch mounted in place convenient for personnel operation.
Overload Limiter
When overload limiter load reaches 90% of its rated load, issued a suggestive alarm signal, when the load reaches 110% of its rated load, immediately cut off the lifting power source and issued prohibitive alarm signal.
Travel limit
Crane limit limiter including ordinary limit switch, and higher performance, smaller size, more accurate limit space photoelectric switch or laser anti-collision device.
Off phase, wrong phase, overvoltage, low voltage protection
Crane circuit system integrated protection with off phase, wrong phase, over voltage, low voltage protection, and will automatically cut off crane total power when the above four cases occurred to prevent personal injury and equipment damage.
Ground Connection
Crane’s metal body and metal casing, ducts, low voltage side of the transformer of all electrical equipment are equipped with reliable ground connection protection.
