| The main bearing force mechanisms of QLH series fabricated gantry crane are triangle truss which of dual stations hang weight, also hang weight as single machine, It is equipped self-walking and hoisting equipment and achieve omnidirectional mechanization action, It is used for shifting beam in beam fabricating yard and erecting high pier bridge. FEATURES: 1. Convenient dismounting of whole machine, low freight, secure and highly available, nice appearance. 2. The main hoisting mechanisms design reasonably, drive dynamic adopts closed design, reducer output shaft special machined are quipped hoisting upper or lower limit device to ensure safe and reliable in process. 3. QLH series gantry crane adopts triangle truss separation type pin-connected girder which is performed fixture making, no pre-supplying degrees, compared to tetragonal truss, its steel girder is more stability and stronger steel degrees. 4. The girder is equipped crown block walking rail to save acquisition cost and human resource foe clients. 5. Walking cart has some features of nice appearance, long service life, small noise, more safe and reliable. 6. Operation control device implement concentrated electronic button operation which is controlled by single machine and concatenated machine.
