Single Girder Crane main components including: bridge frame, electric hoist, and electric control system. According to single girder crane operation site actual situation, its operation mode can be selected as ground pedant operation, wireless remote operation or driver’s cabin. Single Girder Crane main traveling mechanism adopt soft start motor, smooth and quiet operation, its traveling speed can be designed double speed and frequency control or other types of speed.

Single Girder Crane Bridge Steel Structure Part
Electric Single Girder Crane bridge frame consisted of main girder and end girder. End girder mechanism including traveling motor, reducer, wheel set, rubber buffers and so on.

Single Girder Crane Main Girder
Single girder crane main beam is the main carrier structure; 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 set with board connections. Main girder made ​​into upper camber as required, camber degree not less than horizontal level under the rated capacity, main without permanent deformation during normal working.

Single Girder Crane Driving Unit
Single Girder Crane 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, heat treatment hardness is 235-269HB.
Single Girder Crane Motor
Single Girder Crane Motor adopt soft start motor, to achieve start from slow speed to normal speed finally reach stability; which solved impact operation compared to the normal motor and applicable to frequent start, energy saving and environmental protection situation. Standard Motor insulation class is B, protection class IP44, also can made ​​to F, H insulation class, IP54, IP55 protection class according to working condition requires.

Single Girder Crane Wheel Set
Single Girder Crane Wheel set made ​​of 45 # steel, made after ​​precision machining and heat treatment, heat treatment hardness 300-380HB, hardened layer not less than 260HB at a depth of 15mm.
Single Girder Crane Electrical generally use Mitsubishi, Yaskawa, Siemens, Schneider and related brands.
Single Girder Crane Electrical Protection Systems
Single Girder Crane Emergency power-off switch
Single Girder Crane set with red mushroom head type rotary reset emergency power off switch for emergency situations quickly cut off main power and control circuit of the single girder crane. Emergency power off switch mounted in the place convenient for worker operation.
Single Girder Crane Overload Limiter
When Single Girder Crane load reaches 90% of its rated load, single girder crane overload limiter issued suggestive alarm signal; when the load reaches 110% of its rated load, single girder crane limit switch immediately cut off the lifting power source and issued prohibitive alarm signal.
Single Girder Crane Travel limit
Single Girder Crane Lifting mechanism equipped with up and down fire stopper, as the limit switch of lifting mechanism, it also has protective effect against the controller adhesions.
Single Girder Crane travel limit including common limit switch, and higher performance, smaller size, more accurate limit space photoelectric switch or laser anti-collision device.
